Description

Technical Field

[0001] This utility model pertains to testing equipment, specifically a testing device for the pins of a flexible printed circuit board connector. Background Technology

[0002] The pins of existing flexible printed circuit board (Flexible Printed Circuit Board) connectors need to be inspected to prevent pin misalignment from affecting the connection. Existing inspection equipment includes a camera and a worktable; the camera is fixed to the equipment, while the worktable can slide back and forth. Since there are various types of Flexible Printed Circuit Boards (FTPCBs), and the pin orientations of different FTPCB connectors vary, the existing equipment can only inspect FTPCBs whose pins can face the camera (to the left or right). Specifically, multiple FTPCBs are placed on the worktable, and the worktable moves the connectors of the FTPCBs to a position opposite the camera for inspection. For FTPCBs with pins facing forward or backward, placing the camera in front of or behind the FTPCB results in the camera being blocked by the first FTPCB, thus obstructing the inspection of the FTPCBs in the middle. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a testing device for the pins of flexible printed circuit board connectors.

[0004] To achieve the above objectives, this utility model discloses a testing device for the pins of a flexible printed circuit board connector, including a worktable, a support structure, a pusher, a connecting assembly, and a testing module;

[0005] The support structure and connecting components are disposed on the workbench. The support structure is used to place multiple flexible printed circuit boards, and there is a clearance space between the support structure and the workbench.

[0006] The pusher is movably connected to the worktable and located below the support structure. The pusher can move to a first position within the clearance space so that the connector can be retracted, and can move to a second position extending out of the clearance space so that the connector can be lifted.

[0007] There are multiple pushers, and one pusher is used to push up one connector;

[0008] The connecting assembly includes a column, a crossbeam, and a connector. The column is mounted on the workbench, one end of the crossbeam is connected to the top of the column, and the crossbeam is arranged along the width direction of the load-bearing structure. The connector is arranged along the vertical direction, one end of the connector is slidably connected to the measuring device, and the detection module is rotatably connected to the other end of the connector so that the detection module can be turned to the second position.

[0009] Preferably, the pusher is slidably connected to the worktable, and the pusher can slide into the clearance space to make the connector droop under its own weight, and can move to extend out of the clearance space to lift the connector.

[0010] Preferably, in the first position, the pusher is in contact with the connector.

[0011] Preferably, in the first position, the surface of the pusher that is opposite to the connector is the first surface, and the first surface is connected to the top surface of the pusher by an arc surface.

[0012] Preferably, the pushing component is a robotic arm.

[0013] Preferably, the detection module includes a camera, a first light source, and a second light source, with the first light source located above and below the camera, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention discloses a testing device for flexible printed circuit boards (PCBs) with connectors facing forward or backward. Multiple PCBs can be placed side-by-side on a support structure, while the connectors are not placed on the support structure and droop under gravity. When testing the connector pins of the first PCB connector, a first pusher lifts the connector. If the connector pins face forward, the testing module directly performs the test. If they face backward, the testing module is moved to the rear of the connector and rotated to face it for testing. After testing, the pusher moves into a clearance space, and the connector droops. This prevents the connector from obstructing or interfering with the testing of subsequent connectors. Subsequent connectors are tested following the same procedure.

[0016] By setting up a pusher to lift the connector or make the connector droop, it is possible to avoid the tested connector blocking the light or interfering with the testing module. The connecting component can drive the testing module to move to the front or back of the connector for testing. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] A testing device for the pins of a flexible printed circuit board connector, see [link / reference]. Figures 1-3 The system includes a worktable 1, a support structure 2, a pusher 3, a connecting assembly 4, and a detection module 5. The support structure 2 and the connecting assembly 4 are mounted on the worktable 1. The support structure 2 holds multiple flexible printed circuit boards, and a clearance space 11 exists between the support structure 2 and the worktable 1. The pusher 3 is movably connected to the worktable 1 and located below the support structure 2. The pusher 3 can move into the clearance space 11 to a first position where the connector 6 is retracted, and can move out of the clearance space 11 to a second position where the connector can be lifted. Multiple pushers 3 are available, and the specific number can be set as needed; one pusher 3 is used to lift one connector. The connecting component 4 includes a column 41, a crossbeam 42, and a connector 43. The column 41 is mounted on the workbench 1. One end of the crossbeam 42 is connected to the top of the column 41. The crossbeam 42 is arranged along the width direction of the bearing structure 2 (in this embodiment, the width direction is the width direction of the flexible printed circuit board, which is consistent with the front and back of the prior art). The connector 43 is arranged in the vertical direction. One end of the connector 43 is slidably connected to the crossbeam. The detection module 5 is rotatably connected to the other end of the connector 43, thereby enabling the detection module 5 to rotate to a second position.

[0028] In this embodiment, the testing device allows multiple flexible printed circuit boards (PCBs) with connectors facing forward or backward to be placed side-by-side on the support structure 2. The connectors are not placed on the support structure 2 and hang down under gravity. When testing the connector pins of the first PCB, the first pusher 3 lifts the connector. If the connector pins face forward, the testing module 5 directly tests it. If they face backward, the testing module 5 is moved to the rear of the connector and rotated to face the connector for testing. After testing, the pusher 3 moves into the clearance space 11, and the connector hangs down. This prevents the connector from blocking or interfering with the testing of subsequent connectors. Subsequent connectors are also tested following the same steps. By using the pusher 3 to lift or hang the connector, the tested connectors are prevented from blocking light or interfering with the testing module 5. The connecting component 4 can move the testing module 5 to the front or rear of the connector for testing. Compared to existing devices, this method offers better versatility and testing efficiency.

[0029] In this embodiment, the pusher 3 is slidably connected to the worktable 1. The pusher 3 can slide into the clearance space 11 to allow the connector to droop under its own weight, and can also move out of the clearance space 11 to lift the connector, so that the connector is in a horizontal state. The connector is directly lifted by the sliding pusher 3, which has a simple structure and lower cost compared to the robot arm solution.

[0030] In the first position mentioned above, the pusher 3 contacts the connector, which avoids the problem of the connector wobbling in the drooping state and causing damage to the flexible printed circuit board.

[0031] In the aforementioned first position, the surface of the pusher 3 opposite to the connector is the first surface. The first surface and the top surface of the pusher 3 are connected by an arc surface. In this way, the pusher 3 is less likely to damage the flexible printed circuit board during the pushing process.

[0032] In other alternative embodiments, the pusher 3 is a robotic arm, which changes the position of the connector. The position control accuracy is higher, which can improve the detection effect.

[0033] In this embodiment, the detection module 5 includes a camera 51, a first light source 52, and a second light source 53. The first light source and the second light source are located above and below the camera, respectively. The two light sources can provide sufficient illumination and improve the detection effect.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
