Description

Technical Field

[0001] This invention relates to the field of electrical testing technology, and in particular to a product electrical safety testing system. Background Technology

[0002] Electrical safety testing and operational testing are the two most crucial steps in determining the quality of an air conditioner's outdoor unit. After the basic components are assembled, the outdoor unit must undergo electrical safety and operational testing. Currently, most testing methods involve first conducting an electrical safety test (withstand voltage test), and then placing the outdoor unit in an operating room for operational testing. This process requires manual supervision, and the two separate steps can easily lead to stagnation and accumulation of outdoor units, prolonging the transportation time between production lines, resulting in decreased equipment utilization, increased production costs, and reduced overall production efficiency.

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

[0004] Therefore, there is a need for a testing system that can perform parallel electrical safety tests on multiple air conditioner outdoor units, with each unit's testing process being independent of the others, and that will not cause a shutdown when the electrical safety test result of one of the air conditioner outdoor units is abnormal. Summary of the Invention

[0027] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0028] Example 1

[0029] like Figure 1As shown, this embodiment provides a product electrical safety testing system, including a control device. The control device is electrically connected to a withstand voltage tester 1, which is electrically connected to N products. The N products are connected in parallel. Both the control device and the withstand voltage tester 1 are electrically connected to a host computer 3. The host computer 3 is used to receive the start signal from the control device and control the withstand voltage tester 1 to perform electrical safety tests on different products in sequence. Wherein, N≥1.

[0030] Communication methods are divided into serial communication and parallel communication. Serial communication uses a single data line to transmit data bit by bit, in units of bytes; parallel communication uses multiple data lines to transmit each bit of data simultaneously. Serial communication has simpler communication lines and lower cost, making it suitable for long-distance transmission. Parallel communication is characterized by its faster data transmission speed, making it suitable for short-distance transmission.

[0031] This embodiment takes serial communication between the control device and the withstand voltage tester 1 as an example. The serial communication adopts the RS232 protocol. Two data lines are used to electrically connect the control device and the withstand voltage tester 1. One data line sends the command signal issued by the control device to the withstand voltage tester 1, and the other data line sends the feedback signal of the withstand voltage tester 1 to the control device.

[0032] In this embodiment, the product is an air conditioner outdoor unit, N=8, and 8 installation stations 10 are set up, with each of the 8 air conditioner outdoor units placed on its corresponding installation station 10. The control module is connected to a scanning device, which scans the QR code on the air conditioner outdoor unit. The scanning device then sends the scan result to the control module. The control module sends the scan result and a start signal to the host computer 3. Upon receiving the start signal, the host computer 3 controls the withstand voltage tester 1 to perform an electrical safety test on the air conditioner outdoor unit, and the withstand voltage tester 1 feeds back the test result to the host computer 3.

[0033] Electrical safety testing includes AC withstand voltage testing, DC withstand voltage testing, insulation resistance testing, and grounding resistance testing. AC withstand voltage testing involves applying high AC voltage between the live and non-live parts of an electrical appliance, such as the casing, to check the withstand voltage capability of the appliance's insulation material. DC withstand voltage testing involves applying DC voltage to the insulation structure of the device under test, increasing the voltage amplitude until the test time ends.

[0034] Insulation resistance testing is a common method for detecting the grounding condition of electrical equipment. It determines the grounding status of the equipment by measuring the resistance between the insulating materials. If the insulation resistance value is lower than the specified value, it indicates a possible grounding fault. An insulation resistance tester is typically used to measure the insulation resistance. Grounding resistance testing is a method specifically used to detect the quality of a grounding system. It evaluates the performance of the grounding system by measuring the resistance between the grounding electrode and the earth. A grounding resistance tester is generally used to measure the grounding resistance. The grounding resistance value should meet relevant standards, typically requiring it to be below a certain limit, such as 4Ω.

[0035] Preferably, after receiving the test results, the host computer 3 determines whether the test results are qualified and displays the determination results on the display screen.

[0036] This embodiment provides a product electrical safety testing system, including a control device electrically connected to a withstand voltage tester 1. The withstand voltage tester 1 is electrically connected to N products; the N products are connected in parallel. Both the control device and the withstand voltage tester 1 are electrically connected to a host computer 3. The host computer 3 receives the start signal from the control device and controls the withstand voltage tester 1 to perform electrical safety tests on different products; where N ≥ 1. After the control module selects the product to be tested, such as an air conditioner outdoor unit, it sends a start signal to the host computer 3. The host computer 3 receives the start signal and controls the withstand voltage tester 1 to perform electrical safety tests on the product to be tested according to the start signal. After the test is completed, the withstand voltage tester 1 sends the test result to the host computer 3. The host computer 3 then receives the start signal from the control device for the next product and controls the withstand voltage tester 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 for each product is parallel and independent. After the test is completed, the test result of each product is uploaded to the host computer 3. When the electrical safety test result of a product is abnormal, there will be no line stoppage.

[0037] Example 2

[0038] like Figure 1 As shown, this embodiment provides a product electrical safety testing system, including a control device. The control device is electrically connected to a withstand voltage tester 1, which is electrically connected to N products. The N products are connected in parallel. Both the control device and the withstand voltage tester 1 are electrically connected to a host computer 3. The host computer 3 is used to receive the start signal from the control device and control the withstand voltage tester 1 to perform electrical safety tests on different products in sequence. Wherein, N≥1.

[0039] like Figure 2As shown, the control device includes an industrial computer 2, which includes a first data transmitting end 4 and a first data receiving end 5. The withstand voltage tester 1 includes a second data transmitting end 6 and a second data receiving end 7. The first data transmitting end 4 is electrically connected to the second data receiving end 7, and the first data receiving end 5 is electrically connected to the second data transmitting end 6.

[0040] The communication between the industrial computer 2 and the withstand voltage tester 1 uses the RS232 protocol. The first data transmitter 4, the first data receiver 5, the second data transmitter 6, and the second data receiver 7 all use RS232 ports. Two data cables are used to electrically connect the industrial computer 2 and the withstand voltage tester 1. One data cable is electrically connected to the first data transmitter 4 and the second data receiver 7 at both ends, and the other data cable is electrically connected to the first data receiver 5 and the second data transmitter 6 at both ends. The data cables are two-core shielded cables, which reduce interference from external electromagnetic fields on the communication lines.

[0041] The product electrical safety testing system also includes a barcode scanner 9, which is electrically connected to the control device and is used to scan the QR code of the product to be tested.

[0042] This embodiment uses eight installation stations 10 as a test group, with each test group equipped with an industrial control computer 2 and a barcode scanner 9, and the barcode scanner 9 electrically connected to the industrial control computer 2 as an example. The barcode scanner 9 includes a light source, a photoelectric receiver, a photoelectric converter, a decoding circuit, and a computer interface. The basic working principle of the scanner is as follows: light emitted from the light source shines onto the QR code through an optical system. The reflected light is imaged onto the photoelectric converter through the optical system, and the optical signal is converted into a digital signal that can be directly read by the computer through the decoding circuit. The computer interface then sends the digital signal to the control device.

[0043] Communication between the host computer 3 and the withstand voltage tester 1 uses the RS485 protocol. The industrial computer 2 controls the barcode scanner 9 to scan the QR code on the outdoor unit of the air conditioner to be tested, and the barcode scanner 9 sends the scanning result to the industrial computer 2. The industrial computer 2 sends the scanning result and a start signal to the host computer 3. After receiving the start signal, the host computer 3 sends a test signal to the withstand voltage tester 1. After receiving the test signal, the withstand voltage tester 1 performs electrical safety tests on the outdoor unit of the air conditioner corresponding to the QR code and obtains the test results. The electrical safety tests include AC withstand voltage test, DC withstand voltage test, insulation resistance test, and grounding resistance test.

[0044] The withstand voltage tester 1 sends the test results to the host computer 3. The host computer 3 compares the test results with the upper and lower limits of the test value. If the test result is within the range formed by the upper and lower limits of the test value, the test result is considered qualified; if the test result is outside the range formed by the upper and lower limits of the test value, the test result is considered unqualified. The host computer 3 displays the test results and judgment results on the test interface of the display screen. The industrial control computer 2 then controls the barcode scanner 9 to scan the barcode of the next air conditioner outdoor unit, and repeats the above test process until all 8 air conditioner outdoor units in a test group have been tested.

[0045] The control device in this embodiment includes an industrial computer 2, which includes a first data transmitting end 4 and a first data receiving end 5. The withstand voltage tester 1 includes a second data transmitting end 6 and a second data receiving end 7. The first data transmitting end 4 is electrically connected to the second data receiving end 7, and the first data receiving end 5 is electrically connected to the second data transmitting end 6. The product electrical safety testing system also includes a barcode scanner 9, which is electrically connected to the control device. The barcode scanner 9 is used to scan the QR code of the product to be tested. The barcode scanner 9 converts the QR code on the surface of the air conditioner outdoor unit into a digital signal and sends the digital signal to the industrial computer 2. The industrial computer 2 assigns a number to the air conditioner outdoor unit to be tested, generates a start signal according to the number, and sends the scanning result and the start signal to the host computer 3. After receiving the start signal and the scanning result, the host computer 3 controls the withstand voltage tester 1 to perform an electrical safety test on the air conditioner outdoor unit corresponding to the scanning result.

[0046] Example 3

[0047] like Figure 1 As shown, this embodiment provides a product electrical safety testing system, including a control device. The control device is electrically connected to a withstand voltage tester 1, which is electrically connected to N products. The N products are connected in parallel. Both the control device and the withstand voltage tester 1 are electrically connected to a host computer 3. The host computer 3 is used to receive the start signal from the control device and control the withstand voltage tester 1 to perform electrical safety tests on different products in sequence. Wherein, N≥1.

[0048] like Figure 2 As shown, the control device includes an industrial computer 2, which includes a first data transmitting end 4 and a first data receiving end 5. The withstand voltage tester 1 includes a second data transmitting end 6 and a second data receiving end 7. The first data transmitting end 4 is electrically connected to the second data receiving end 7, and the first data receiving end 5 is electrically connected to the second data transmitting end 6.

[0049] The product electrical safety testing system also includes a switch 8, the input of which is electrically connected to the industrial control computer 2, and the output of which is electrically connected to N products; wherein, the industrial control computer 2 controls the switch 8 to select the product to be tested.

[0050] In this embodiment, eight installation stations 10 are used as a test group. Each test group is equipped with an industrial control computer 2 and a barcode scanner 9. The barcode scanner 9 is electrically connected to the industrial control computer 2. Each test group is also equipped with a switch.

[0051] The input terminals of switch 8 are electrically connected to the location selection terminals of industrial control computer 2 via shielded network cables, and the output terminals of switch 8 are electrically connected to eight installation stations 10. The location selection terminals of industrial control computer 2 send location selection signals to switch 8. Switch 8 selects the corresponding installation station 10 based on the location selection signals, and uses switch 8 to transmit data between industrial control computer 2 and the corresponding installation station 10. Through switch 8, industrial control computer 2 can be electrically connected to any installation station 10, allowing the selection of the next air conditioner outdoor unit after testing the current one, and then testing the next air conditioner outdoor unit.

[0052] like Figure 3 As shown, the third data receiving end 12 of the host computer 3 is electrically connected to the control device, and the third data sending end 13 of the host computer 3 is electrically connected to the withstand voltage meter 1.

[0053] The industrial computer 2 sends the scanning result and start signal to the third data receiving terminal 12 of the host computer 3. After receiving the scanning result and start signal, the third data sending terminal 13 of the host computer 3 sends the scanning result and start signal to the withstand voltage tester 1 to control the withstand voltage tester 1 to perform electrical safety testing on the selected air conditioner outdoor unit.

[0054] The industrial control computer 2 can be directly electrically connected to the host computer 3, or it can be electrically connected to the host computer 3 through the switch 8. There is no limitation here. In this embodiment, the industrial control computer 2 is directly electrically connected to the host computer 3 as an example.

[0055] The product electrical safety testing system in this embodiment also includes a switch 8. The input terminal of the switch 8 is electrically connected to the bit selection terminal of the industrial control computer 2, and the output terminal of the switch 8 is connected to N products. The industrial control computer 2 controls the switch 8 to select the product to be tested. The bit selection terminal of the industrial control computer 2 sends a bit selection signal to the switch 8. The switch 8 selects the corresponding installation station 10 based on the bit selection signal, and uses the switch 8 to transmit data between the industrial control computer 2 and the corresponding installation station 10. Through the switch 8, the industrial control computer 2 can be electrically connected to any installation station 10, so that after testing the current air conditioner outdoor unit, the next air conditioner outdoor unit can be selected and tested.

[0056] Example 4

[0057] like Figure 1 As shown, this embodiment provides a product electrical safety testing system, including a control device. The control device is electrically connected to a withstand voltage tester 1, which is electrically connected to N products. The N products are connected in parallel. Both the control device and the withstand voltage tester 1 are electrically connected to a host computer 3. The host computer 3 is used to receive the start signal from the control device and control the withstand voltage tester 1 to perform electrical safety tests on different products in sequence. Wherein, N≥1.

[0058] like Figure 2 As shown, the control device includes an industrial computer 2, which includes a first data transmitting end 4 and a first data receiving end 5. The withstand voltage tester 1 includes a second data transmitting end 6 and a second data receiving end 7. The first data transmitting end 4 is electrically connected to the second data receiving end 7, and the first data receiving end 5 is electrically connected to the second data transmitting end 6.

[0059] The product electrical safety testing system also includes a switch 8, the input of which is electrically connected to the selection terminal of the industrial control computer 2, and the output of which is electrically connected to N products; wherein, the industrial control computer 2 controls the switch 8 to select the product to be tested, and in this embodiment, the product is an air conditioner outdoor unit.

[0060] The product electrical safety testing system also includes N installation stations 10, one of which is equipped with the withstand voltage tester 1.

[0062] In this embodiment, eight installation stations 10 are used as a test group, i.e., N=8. Each installation station 10 is equipped with a housing 11. One housing 11 contains a withstand voltage tester 1, and the other housing 11 contains a switch 8. The withstand voltage tester 1 and the switch 8 are respectively located in two different housings 11, i.e., the withstand voltage tester 1 is located in the i-th housing 11, and the switch 8 is located in the j-th housing 11, where i≠j.

[0063] As an example, the distance from the host computer 3 to the pressure tester 1 is 10 meters, and the distance from the host computer 3 to the enclosure 11 is 8 meters.

[0064] Preferably, each installation station 10 is equipped with an indicator light, which is electrically connected to the industrial control computer 2. When an air conditioner outdoor unit enters the installation station 10, the barcode scanner 9 scans the QR code on the air conditioner outdoor unit to obtain the scanning result. The industrial control computer 2 sends the scanning result and start signal to the host computer 3 in sequence. The host computer 3 controls the withstand voltage tester 1 to perform electrical safety tests on each air conditioner outdoor unit in sequence. The test results in the middle do not affect the subsequent tests; that is, if the i-th air conditioner outdoor unit fails the test, the test continues on the (i+1)-th air conditioner outdoor unit. For air conditioner outdoor units that fail the test, the industrial control computer 2 controls the corresponding indicator light to turn red. After N air conditioner outdoor units have been tested, the industrial control computer 2 sends a retest signal to the host computer 3 to perform electrical safety tests again on the air conditioner outdoor units that failed the test.

[0065] Each installation station 10 is equipped with a test operation button panel, which has a green button and a red button. The green button is the test start button; pressing the test start button begins testing the outdoor unit of the air conditioner. The red button is the reset button; pressing the reset button after the test is completed stops testing the outdoor unit and adjusts the test parameters to the preset parameters. An emergency stop button is located between the test start button and the reset button; pressing the emergency stop button immediately stops the electrical safety test of the outdoor unit.

[0066] Each enclosure 11 is also equipped with a power supply. The power supply in each enclosure 11 is hardware-interlocked with the withstand voltage tester 1 to prevent mutual interference between the power supply and the withstand voltage tester 1. The hardware interlock is achieved using an interlock circuit. The N installation stations 10 are software-interlocked to prevent the test results of the air conditioner outdoor unit on one installation station 10 from affecting the test results of the air conditioner outdoor unit on another installation station 10. The software interlock is achieved using an interlock program.

[0067] Preferably, each installation station 10 is provided with a box 11, and there are N boxes 11 in total. A check box is provided in one of the boxes 11. The check box is used to check the accuracy, function and connection of the test lines of the product electrical safety test system after the product electrical safety test system is started.

[0068] The product electrical safety testing system of this embodiment also includes N installation stations 10, one of which is equipped with a withstand voltage tester 1. Each installation station 10 is equipped with a housing 11, and the withstand voltage tester 1 is installed inside the i-th housing 11. Each installation station 10 is equipped with a housing 11, the i-th housing 11 is equipped with a withstand voltage tester 1, and the j-th housing 11 is equipped with a switch 8. The N installation stations 10 form a test group, and each test group is equipped with a withstand voltage tester 1 and a switch 8. Using the switch 8, the first to Nth outdoor air conditioner units can be electrically connected to the industrial control computer 2 in sequence. The industrial control computer 2 sends corresponding test signals to the host computer 3. The host computer 3 controls the withstand voltage tester 1 to perform electrical safety tests on each outdoor air conditioner unit in sequence according to the test signals until all N outdoor air conditioner units have been tested.

[0080] In this embodiment, the product is an air conditioner outdoor unit, N=8, with 8 installation stations 10 forming a test group. Each test group is equipped with an industrial control computer 2 and a barcode scanner 9. After the barcode scanner 9 scans the QR code on the i-th air conditioner outdoor unit, the industrial control computer 2 sends the scanning result and a start signal to the host computer 3. Upon receiving the start signal, the host computer 3 controls the withstand voltage tester 1 to perform an electrical safety test on the i-th air conditioner outdoor unit. The withstand voltage tester 1 feeds back the test result of the i-th air conditioner outdoor unit to the host computer 3. The host computer 3 displays the test result on the test interface of the monitor. The host computer 3 compares the test result with the lower limit and upper limit of the test value. If the test result is greater than the lower limit and less than the upper limit, the test is considered passed, and the i-th air conditioner outdoor unit is deemed qualified. The host computer 3 displays the judgment result as OK or NG on the test interface of the monitor.

[0081] This embodiment provides a product electrical safety testing method, including controlling a barcode scanner to scan the QR code of the k-th product to obtain the k-th scan result, where 1 ≤ k ≤ N. The k-th scan result and a start signal are received and sent to the withstand voltage tester 1. The withstand voltage tester 1 is then controlled to perform an electrical safety test on the k-th product to obtain the k-th test result. This embodiment employs a parallel testing method, ensuring that the testing process and results of the outdoor units of each installation station 10 are independent, preventing a situation where a failed test of one outdoor unit prevents the testing of the next outdoor unit from proceeding.

[0082] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this application. Any specific values ​​in all examples shown and discussed herein should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0083] It should be understood that spatial relative terms are intended to encompass different orientations of a device in use or operation, in addition to the orientation described in the figures. For example, if a device in the figures is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0084] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0085] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
