Description

Technical Field

[0001] This utility model relates to the field of PCB board testing technology, and more specifically to a PCB board adaptive testing fixing device. Background Technology

[0002] PCB is the basic platform for carrying and connecting electronic components in electronic devices. PCB testing refers to the various tests and verification processes performed on printed circuit boards. PCB testing can ensure the quality and performance of PCB boards and prevent product failures due to defects.

[0003] Currently, when testing PCBs using testing equipment, only one PCB can be tested at a time. In practice, the operator needs to place the PCB on the support bracket, then operate the clamp to press and fix the PCB. After the PCB is tested, the operator operates the clamp to release the PCB, remove the PCB, and then place other PCBs to be tested, and operate the clamp again. Throughout the entire process, the operator needs to constantly operate the clamp to press and release, and constantly place and remove PCBs, which is quite cumbersome and inconvenient.

The testing equipment then tests the PCB board located at the bottom. After one PCB board is tested, the operator manually pushes the rotating handle to rotate the rotating disk around the axis of rotation. When the next PCB board moves to the bottom of the testing equipment, the mating block and mating groove cooperate to fix the position of the rotating disk. At this time, the testing equipment will then test the PCB board again.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The PCB board adaptive testing and fixing device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a PCB board adaptive testing and fixing device, including a base 1, a rotating disk 2 on the top of the base 1, a positioning component 3 on the top of the rotating disk 2, multiple positioning components 3 evenly arranged, a rotating component 4 installed between the rotating disk 2 and the base 1, and a control shaft 5 installed at the center of the rotating disk 2. The positioning component 3 is used to press and position the PCB board, the rotating component 4 is used to rotate and adjust the rotating disk 2, and the control shaft 5 is used to control the pressing and releasing of the positioning component 3 on the PCB board.

[0021] Furthermore, the positioning component 3 includes a support frame 31, an extension groove 32, a positioning strip 37, and a transmission rod 35. The support frame 31 is used to place the PCB board and is fixedly installed on the top of the rotating disk 2. The extension groove 32 is opened on the top of the rotating disk 2, and a moving block 33 is provided in the extension groove 32. Guide grooves 321 are opened on both sides of the groove wall of the extension groove 32. Guide strips 331 are fixedly connected to both sides of the moving block 33. The surface of the guide strips 331 is slidably connected to the groove wall of the guide groove 321, and the two form a sliding guide fit. The top of the moving block 33 is fixedly connected to the positioning strip 37 through a connecting frame 34. An internal groove 21 is opened at the center of the top of the rotating disk 2. A control shaft 5 is rotatably installed in the internal groove 21. The surface of the control shaft 5 is... A first bevel gear 51 is fixedly connected. A transmission rod 35 is rotatably mounted on a rotating disk 2. One end of the transmission rod 35 extends into an internal groove 21, and the other end extends into an extension groove 32. A second bevel gear 36 is fixedly connected to one end of the transmission rod 35. The second bevel gear 36 meshes with the first bevel gear 51. A threaded section 351 is provided at the other end of the transmission rod 35. A moving block 33 is threaded onto the surface of the threaded section 351. The operator can manually turn the control shaft 5 to generate rotational force. The first bevel gear 51 and the second bevel gear 36 cooperate to transmit the rotational force of the control shaft 5 to the transmission rod 35. While the transmission rod 35 rotates, it can drive the moving block 33 to move along the axis of the transmission rod 35 through the threaded section 351.

[0022] Furthermore, the rotating assembly 4 includes a rotating shaft 41, the bottom end of which is rotatably connected to the top of the base 1, and the top end of which is fixedly connected to the center of the bottom of the rotating disk 2. A rotating handle 42 is fixedly connected to the surface of the rotating shaft 41, and a limiting ring 43 is sleeved on the surface of the rotating shaft 41. The bottom of the limiting ring 43 is fixedly connected to the top of the base 1. A mounting groove 44 is formed on the surface of the rotating shaft 41, and multiple mounting grooves 44 are evenly arranged corresponding to the positioning assembly 3. A compression spring 45 is installed in the mounting groove 44, and one end of the compression spring 45 is fixedly connected to the bottom of the mounting groove 44. The other end of the compression spring 45 is fixedly connected to a docking block 46 with an arc-shaped block structure. The inner side of the limiting ring 43 is provided with a docking groove with an arc-shaped groove structure. The docking block 46 matches the docking groove. The elastic force of the compression spring 45 can drive the docking block 46 into the docking groove. The docking block 46 and the docking groove cooperate to fix the position of the rotating disk 2. When the docking block 46 moves between the docking grooves, the operator can feel the jerking sensation, so as to accurately control the position of the rotating disk 2 and ensure that the PCB board is accurately placed at the bottom of the testing equipment during each test.

[0023] The working principle of this utility model is as follows: The operator places the PCB board into the support frame 31 and manually rotates the control shaft 5 to make the first bevel gear 51 rotate around the axis of the control shaft 5. The rotation of the first bevel gear 51 drives the transmission rod 35 to rotate synchronously around its own axis through the second bevel gear 36. The rotation of the transmission rod 35 drives the moving block 33 to move synchronously through the threaded section 351. During this process, the guide bar 331 slides synchronously along the guide groove 321. The movement of the moving block 33 drives the positioning bar 37 to move synchronously through the connecting frame 34. The positioning bar 37 presses and positions the PCB board in the support frame 31.

[0024] The testing equipment tests the PCB board located at its bottom. After one PCB board is tested, the operator manually pushes the rotating handle 42 to make the rotating shaft 41 rotate around its own axis. The rotating shaft 41 rotates and drives the rotating disk 2 to rotate synchronously around the axis of the rotating shaft 41. During the rotation of the rotating shaft 41, the mating block 46 is squeezed into the mounting groove 44 by the limiting ring 43. The compression spring 45 is compressed and its elastic force increases under the compression of the mating block 46. When the next PCB board moves to the bottom of the testing equipment, the mating block 46 is aligned with the mating groove. The elastic force of the compression spring 45 drives the mating block 46 into the mating groove. The mating block 46 and the mating groove cooperate to fix the position of the rotating disk 2. At this time, the testing equipment tests the PCB board again. This cycle is repeated to complete the testing of all PCB boards on the top of the rotating disk 2.
