Figure 2 A side view of the tooling plate provided in an embodiment of the present application. Figure 3 The main view of the tooling board provided in the embodiment of the present application is first. Figures 1 to 3 As shown, an embodiment of the present application provides a circuit board testing device 1000 , comprising a tooling board 1100 for mounting a circuit board and a testing assembly 1200 for testing the circuit board on the tooling board 1100 .
[0034] The tooling board 1100 has a mounting surface 1110 , which has multiple mounting positions 1111 , and the mounting positions 1111 are used to mount circuit boards. The tooling board 1100 includes an electrical connection portion 1120 , and the electrical connection portion 1120 is used to electrically connect to the circuit boards on each mounting position 1111 .

The mounting position 1111 connecting portion is electrically connected to the electrical connecting portion 1120 to achieve electrical connection between the electrical connecting portion 1120 and the circuit board on each mounting position 1111.
[0036] The test assembly 1200 is used to be electrically connected to the electrical connection portion 1120 to test the circuit board on each mounting position 1111 .

The circuit boards are electrically connected to the mounting location 1111 connection portions on their respective mounting locations 1111. Since the mounting location 1111 connection portions are electrically connected to electrical connection portions 1120 of tooling board 1100, and test assembly 1200 is electrically connected to electrical connection portions 1120, the performance of the circuit boards mounted on each mounting location 1111 on tooling board 1100 can be tested using test assembly 1200. There can be multiple mounting locations 1111 on tooling board 1100, including but not limited to six.
[0039] The circuit board can be a PCBA (Printed Circuit Board Assembly, i.e. a PCB (printed circuit board, also known as printed circuit board, printed wiring board, Printed Circuit Board, PWB (Printed Wiring Board)) blank board that has undergone SMT (Surface-mount Technology, an electronic assembly technology that mounts electronic components such as resistors, capacitors, transistors, integrated circuits, etc. onto a printed circuit board and forms electrical connections through soldering).
[0040] The present application utilizes a tooling board 1100 for mounting circuit boards and a test assembly 1200 for testing the circuit boards on the tooling board 1100 to cooperate with each other.

Simultaneously, the performance of the circuit boards on each mounting position 1111 on the tooling board 1100 can be tested simultaneously using the test assembly 1200.

[0042] Among them, the positioning piece 1220 is connected to the positioning part 1300 on the tooling board 1100 to locate and fix the position of the tooling board 1100, so that when the test component 1200 tests the circuit board on the tooling board 1100, the test component 1200 is electrically connected to the electrical connection part 1120 on the tooling board 1100.

[0046] The electrical connector 1210 is aligned with the electrical connector 1120 by first aligning the positioning member 1220 with the positioning portion 1300, and then the electrical connection between the electrical connector 1210 and the electrical connector 1120 is achieved through the positioning member 1220 and the positioning portion 1300. The testing equipment 1230 may include various types, including but not limited to equipment for testing aging and equipment for testing whether a product is good.

[0048] Optionally, the electrical connector 1210 and the electrical connector portion 1120 are plugged together to electrically connect the electrical connector 1210 and the electrical connector portion 1120.

[0051] Optionally, the positioning member 1220 is plugged into the positioning portion 1300. By plugging the positioning member 1220 and the positioning portion 1300 into each other, the position of the tooling plate 1100 is fixed, and the electrical connector 1210 and the electrical connector 1120 can be aligned and plugged simultaneously when the positioning member 1220 and the positioning portion 1300 are plugged into each other.
[0052] Among them, in the positioning member 1220 and the positioning portion 1300, a limiting column can be set on one of them, and a socket 1310 corresponding to the limiting column can be set on the other, so as to realize the plug-in connection between the positioning member 1220 and the positioning portion 1300.

The plurality of limiting posts of the positioning member 1220 are respectively inserted into the corresponding insertion holes 1310 to fix the position of the tooling plate 1100. By providing the positioning member 1220 with a plurality of limiting posts corresponding to the plurality of insertion holes 1310, the electrical connector 1210 and the electrical connector 1120 can be aligned and connected simultaneously when the positioning member 1220 is plugged into the positioning portion 1300.

[0061] The embodiment of the present application also proposes a test line 2000, which includes a circuit board testing device 1000.

[0063] The circuit board testing device 1000 according to any one of the technical solutions of the above embodiments;
[0064] The first conveying device 2100 has a loading section 2110, a testing section 2120 and a unloading section 2130 which are connected in sequence along the conveying direction. The first conveying device 2100 is used to convey the tooling board 1100 in the circuit board testing device 1000 on which the circuit board is installed from the loading section 2110 to the unloading section 2130 along the conveying direction. The test component 1200 in the circuit board testing device 1000 is located in the testing section 2120. The test component 1200 is used to be electrically connected to the electrical connection part 1120 of the tooling board 1100 conveyed to the testing section 2120 to test the circuit boards on each mounting position 1111 on the tooling board 1100.
[0065] By combining the first conveying device 2100 with the circuit board testing device 1000, the circuit board testing can be automated while increasing the number of circuit boards that can be tested at a single time. At the same time, by arranging multiple tooling plates 1100 with circuit boards installed on the first conveying device 2100, large-scale testing of circuit boards can be achieved.
[0066] Among them, the loading section 2110 in the first conveying device 2100 is used to load the tooling board 1100 with the circuit board installed, the testing section 2120 in the first conveying device 2100 may include one detection area or multiple different types of detection areas to detect the corresponding performance of the circuit board in the corresponding detection area, and the unloading section 2130 in the first conveying device 2100 is used to remove the tested circuit board from the tooling board 1100.
[0067] Specifically, the loading section 2110, the testing section 2120 or the unloading section 2130 of the first conveying device 2100 each includes but is not limited to one device. Here, the loading section 2110, the testing section 2120 or the unloading section 2130 may be a part of the first conveying device 2100 composed of multiple devices, and should not be understood as merely a part of a conveyor belt mechanism.
[0068] Optionally, the test line 2000 includes a second conveying device 2200 , which extends from the unloading section 2130 to the loading section 2110 to convey the tooling plate 1100 from the unloading section 2130 to the loading section 2110 .

[0072] Optionally, the test section 2120 includes multiple sub-conveying sections 2130 distributed sequentially along the height direction of the test line 2000. The input end 2131 and output end 2132 of the sub-conveying section 2130 are connected to the loading section 2110 and the unloading section 2130 in sequence. By providing multiple sub-conveying sections 2130, the circuit boards on multiple tooling plates 1100 can be tested simultaneously by using multiple sub-conveying sections 2130 during the conveying process, effectively improving testing efficiency.
[0073] Among them, a plurality of limiting components may be distributed on each sub-conveying section 2130 along the conveying direction to limit the tooling plate 1100 on the sub-conveying section 2130 for subsequent testing.
[0074] Specifically, the limiting component can be an extendable gas rod, which can be connected to the sub-conveying section 2130. The gas rod is used to extend to abut against the tooling plate 1100 for limiting, and then can be tested by the test component 1200. After the test is completed, the gas rod retracts to allow the tooling plate 1100 to continue moving along the conveying direction.

By providing a test assembly 1200 on each sub-conveying section 2130, circuit boards on multiple tooling boards 1100 can be tested simultaneously during the conveying process using multiple sub-conveying sections 2130.
[0076] Among them, the test component 1200 includes an electrical connector 1210 and a test device 1230 that are electrically connected to each other, and the positioning member 1220 is used to connect with the positioning part 1300 so that the electrical connector 1210 and the electrical connection part 1120 are aligned and electrically connected. During the transportation of each sub-conveying section 2130, the positioning member 1220 in the test component 1200 can be used to limit the tooling board 1100 and electrically connect the circuit board on the tooling board 1100.
[0077] Specifically, each sub-conveying section 2130 may be provided with a plurality of test assemblies 1200 at intervals along the conveying direction, and the distribution positions of the plurality of test assemblies 1200 may correspond to the distribution positions of the tooling plates 1100 on the sub-conveying section 2130 .
[0078] Optionally, the test section 2120 includes a first sub-test section 2140 and a second sub-test section 2150 distributed in sequence along the conveying direction.

The first sub-test section 2140 is provided with a plurality of test components 1200 in sequence along the conveying direction to detect whether the circuit board on the tooling board 1100 of the first sub-test section 2140 is a good product.

Thus, different performance tests of the circuit boards can be implemented in the test section 2120.
