Description

Technical Field

[0001] The present invention relates to the field of electrical testing technology, and in particular to a product electrical safety testing system and method. Background Art

[0002] Electrical safety test and operation test are the two most important steps to determine whether the air conditioner outdoor unit is qualified or not. After the basic components of the air conditioner outdoor unit are assembled, it needs to undergo electrical safety test and operation test. At present, most of the testing methods are to first conduct electrical safety test, that is, withstand voltage test, and then send the air conditioner outdoor unit to the operation room for operation test. During the test process, manual control of the test is required, and the air conditioner outdoor unit is prone to stagnation and accumulation between the two different processes, which prolongs the transportation time of the product between the online processes, resulting in a decrease in equipment utilization, an increase in production costs, and a decrease in overall production efficiency.

[0003] For the electrical safety test of the air conditioner outdoor unit, most of the existing testing methods use industrial robots to replace the electrical safety test, and the industrial robots are used to improve the inspection efficiency. However, this testing method has the following problems: (1) The voltage test and the operation test are two serial processes, that is, the voltage test is performed first, and then the operation test is performed. When a problem occurs in the voltage test, the operation test cannot be performed, which may cause an interruption between the two processes, resulting in line stagnation. (2) When multiple air conditioner outdoor units are tested in a certain order, an abnormality in the electrical safety test of one of the air conditioner outdoor units will cause a line stoppage problem.

[0004] Therefore, there is a need for a testing system that can perform electrical safety tests on multiple air-conditioning outdoor units in parallel, and the testing processes of each air-conditioning outdoor unit are independent of each other.

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0042] Example 1

[0043] like Figure 1 As shown, this embodiment provides a product electrical safety testing system, including a control device, wherein the control device is electrically connected to a withstand voltage instrument 1, and the withstand voltage instrument 1 is electrically connected to N products; the N products are connected in parallel with each other, and the control device and the withstand voltage instrument 1 are both electrically connected to a host computer 3, and the host computer 3 is used to receive a start signal from the control device, and control the withstand voltage instrument 1 to perform electrical safety tests on different products in turn; wherein N≥1.

[0044] Communication methods are divided into serial communication and parallel communication. Serial communication uses one data line to transmit data bit by bit in bytes; parallel communication uses multiple data lines to transmit each bit of data at the same time. The communication line of serial communication is simple and the cost is low. Serial communication is suitable for long-distance transmission. The characteristic of parallel communication is that the data transmission speed is fast, and parallel communication is suitable for short-distance transmission.

[0045] This embodiment takes the serial communication between the control device and the withstand voltage instrument 1 as an example, and the serial communication adopts the RS232 protocol. Two data lines are used to electrically connect the control device and the withstand voltage instrument 1, one of which sends the command signal issued by the control device to the withstand voltage instrument 1, and the other data line sends the feedback signal of the withstand voltage instrument 1 to the control device.

[0046] The product in this embodiment is an air conditioner outdoor unit, N=8, 8 installation stations 10 are set, and the 8 air conditioner outdoor units are placed on the corresponding installation stations 10.

After receiving the start signal, the host computer 3 controls the withstand voltage instrument 1 to perform an electrical safety test on the air conditioner outdoor unit, and the withstand voltage instrument 1 feeds back the test result to the host computer 3.

[0047] Electrical safety tests include AC withstand voltage test, DC withstand voltage test, insulation resistance test and ground resistance test. The AC withstand voltage test is to apply AC high voltage between the live parts and non-live parts of the appliance, such as the casing, to check the withstand voltage capacity of the insulation material of the appliance; the DC withstand voltage test is to apply DC voltage to the insulation structure of the device under test and increase the voltage amplitude until the test time ends.

[0048] Insulation resistance test is a common method to detect the grounding condition of electrical equipment. It determines the grounding condition of the equipment by measuring the resistance value between the insulation materials of the equipment. If the insulation resistance value is lower than the specified value, it means that the equipment may have a grounding fault. Usually, an insulation resistance tester is used to test the insulation resistance value. The grounding resistance test is a method specifically used to detect the quality of the grounding system. It evaluates the performance of the grounding system by measuring the resistance value between the grounding body and the earth. Generally, a grounding resistance tester is used to test the resistance value of the grounding resistance. The resistance value of the grounding resistance should meet the requirements of relevant standards. It is usually required that the resistance value of the grounding resistance is lower than a certain limit, such as 4Ω.

[0049] Preferably, after receiving the test result, the host computer 3 determines whether the test result is qualified and displays the determination result on a display screen.

After the test is completed, the withstand voltage instrument 1 sends the test result to the host computer 3, and the host computer 3 receives the start signal of the next product sent by the control device, and controls the withstand voltage instrument 1 to perform electrical safety tests on the next product until all N products have passed the electrical safety test. The N products are connected in parallel, so that the electrical safety test process of each product is parallel and independent of each other, and the test result of each product is uploaded to the host computer 3 after the test is completed.
