Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliance testing, and in particular to an automatic testing device and a testing system. Background Art

[0002] Before being released to the market, most electrical appliances must undergo commercial inspection and testing. Only after passing these tests can they be released for sale. One stage of commercial inspection and testing is the power-on test, which primarily verifies that the appliance's basic functions are functioning properly. For example, for air conditioners, the power-on test primarily verifies their power on, power off, cooling, and heating functions.

[0003] Currently, when powering on an appliance, workers typically use a remote control to send codes to test various functions. This often involves testing multiple appliances, requiring workers to constantly control the remote to send codes. This reduces testing efficiency over time, leading to overall low efficiency. Furthermore, after completing the test on an appliance, a scanner is required to scan the appliance's order code to switch production. This requires a temporary halt to testing, further reducing efficiency. Summary of the Invention

[0024] See also Figures 1 to 3 , Figure 1 A three-dimensional structural diagram of an automatic testing device provided in one embodiment of the present invention; Figure 2 A front view of an automatic testing device provided by one embodiment of the present invention; Figure 3 This is an electrical schematic diagram of an automatic test device provided by an embodiment of the present invention. Figure 1As shown, the automatic testing device provided by the present invention includes a conveying component 10, a transfer control component 20 and a coding component 30; the conveying component 10 is used to receive a device under test connected to a test fixture; the transfer control component 20 is arranged on one side of the conveying component 10, and includes a device identifier, a wireless communicator and a controller, the device identifier is used to identify the device under test to generate a transfer signal, the controller sends the transfer signal to the test fixture through the wireless communicator to complete the transfer of the device under test, and the controller is also used to receive a test signal sent by the test fixture; the coding component 30 is arranged above the conveying component 10, and is used to control the device under test to perform a test according to the test signal sent by the transfer control component 20.

[0025] Specifically, if Figure 1 and Figure 2As shown, the automatic testing device includes a conveyor assembly 10, a production change control assembly 20, and a code generation assembly 30. The conveyor assembly 10 may include a roller assembly for transporting the device under test, or a conveyor belt 12 for transporting the device under test. The device under test can be any electrical appliance, such as an air conditioner, television, or refrigerator. An air conditioner is used as an example. Before testing, the air conditioner is connected to a test fixture, which includes multiple buttons that simulate the functions of the air conditioner remote control. After the air conditioner is connected to the test fixture, it is transported to the production change control assembly 20 via the conveyor assembly 10. Production change refers to the process of switching from one order to another during the production process due to shipping or testing needs. For example, when testing the same type of air conditioner, different air conditioners, although of the same type, have different order numbers. The order number identifies each air conditioner. After completing testing on one air conditioner, the next air conditioner needs to be tested. This switching process is called production change. The production change control assembly 20 is located on one side of the conveyor assembly 10 and includes a device identifier, a wireless communicator, and a controller. When the device under test is transported to the side of the transfer control component 20, the conveying component 10 stops moving, and the device identifier identifies the electronic tag on the device under test. The device identifier can be a card reader or a code scanning device. The specific identification method can be to identify the electronic tag through the device identifier or to identify the electronic tag through the code scanning device. After successful identification, a transfer signal is generated, and the controller sends the transfer signal to the test tooling. The test tooling completes the transfer and prepares to start testing the device under test. At the same time, the controller can receive control instructions sent by the test tooling through a wireless communicator. The control instructions are usually a series of instructions with a sequence, such as power on, cooling, heating, and power off. Then, the test is carried out and the device under test is tested in the above order. The coding component 30 is arranged above the conveying component 10, and its signal sending end is facing the conveying component 10, which is convenient for controlling the device under test. After receiving the test signal, the controller sends the test signal to the coding component 30. The coding component 30 can include an infrared signal sending device to control the device under test through infrared signals. For example, if the test signal includes power on, cooling, heating, and power off, the code generator 30 sequentially transmits the power on, cooling, heating, and power off commands to the device under test. Once the device under test executes the commands in this order, the test is complete. After the test is complete, the transport assembly 10 transports the device under test to a downstream device for subsequent testing. Simultaneously, the device under test, located on the test fixture, is transported to the production transfer control assembly 20.

[0026] like Figure 3 As shown, Figure 3This is the electrical schematic diagram of the automatic test device. The switching power supply is used to provide power. It can output 220V AC power to 5V, 12V, and 24V DC weak current to meet the power supply requirements of different control boards. The liquid crystal box is connected to the CN2 interface of the communication board via the CN2 interface, so that it can communicate with the communication board via the RS485 protocol, allowing the user to input corresponding control instructions through the display 22. The wireless network transmission module is used to provide wireless communication and is connected to the card reader to receive and send wireless signals. The wireless signals can be transfer signals and test signals. The automatic coding tool control board is used to control the equipment under test for testing. The test tool control board is used to control the automatic coding tool control board. The test tool control board is also connected to the whole machine controller.
