Electronic boards are an important part of electronic products. Different electronic boards can integrate different components to achieve different functions. Some special products will use separate or double-layer electronic boards, such as keyboard products. This type of keyboard product integrates several keys on one or more electronic boards, and realizes all functions through the connection of soft flat cables between the electronic boards. Keyboard products have many functional test items and test contact points and are distributed in different positions, which makes the testing difficult. This type of product is mainly tested manually, which has high labor costs and can only test one test contact point at a time, which has low testing efficiency. In addition, the connection accuracy between the upper and lower products is not high, which will cause large errors during the testing process. Alternatively, multi-point testing is performed by a manipulator. This method requires the cooperation of multiple groups of manipulators to complete the full-function test, which is costly.

It can be seen that before the test, the upper product 6 is placed on the upper test carrier board 4, and the upper product 6 is pressed by the top needle module 5 to form a whole with the upper test module 2. During the test, the upper product 6 and the equipment board are reintegrated into a new test system to test the lower product 10. The upper part of the product remains stationary during each test, and the test accuracy is high. At the same time, the soft cable test module 11 is used to realize the connection between the soft cables of the two parts of the product, which can realize the conduction and testing of the soft cables with higher efficiency.

[0017] like Figure 2 and Figure 4 As shown, in the present embodiment, the top lower needle module 5 comprises a flip base 51, a first flip plate 52, a second flip plate 53, a movable plate 54 and an upper needle block 55, the flip base 51 is arranged on one side of the upper test carrier plate 4, one end of the first flip plate 52 is hinged to the flip base 51, the second flip plate 53 is hinged to one end of the first flip plate 52 close to the flip base 51, the movable plate 54 is connected to the first flip plate 52 through a plurality of linear bearings 56, the upper end of the movable plate 54 cooperates with the second flip plate 53 through a cam connection module 12, the upper needle block 55 is arranged on the movable plate 54, and the second flip plate 53 drives the upper needle block 55 through the cam connection module 12 to cooperate with the connecting end of the upper part product 6. It can be seen that the second flip plate 53 can drive the first flip plate 52 to rotate and press down, so that the upper needle blocks 55 can contact and position the edge of the connecting end of the upper product 6 in an arc before pressing and then press down vertically, which can effectively prevent overpressure caused by displacement of the pressing position.

[0018] like Figure 4 and Figure 5As shown, in this embodiment, the cam connection module 12 includes a cam 121 and a cam plate 122, the cam 121 is arranged at the upper end of the movable plate 54, the cam plate 122 is arranged at one side of the second flip plate 53, the cam 121 is movably matched with the sliding groove 123 on the cam plate 122, and the other end of the second flip plate 53 is matched with the other side of the upper test carrier 4 through the locking module 57. It can be seen that the cam connection module 12 provides driving force and a buffer space for rotation during the downward pressing process of the movable plate 54, so that the upper needle block 55 can better dock with the upper part of the product 6.

It can be seen that the quick clamp 112 can quickly realize the wiring connection between the two parts of the product.

[0024] like Figure 6 As shown, in this embodiment, a scanner module 16 is further provided at the lower end of the support plate 1, and the scanner module 16 is inductively matched with the lower product 10 at the upper end of the lower test carrier 7.
