Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board processing technology, and in particular to a hardness testing device for PCB circuit board processing. Background Technology

[0002] A PCB, also known as a printed circuit board, is an assembly board on an insulating substrate with selectively machined mounting holes, connecting wires, and pads for assembling and soldering electronic components to achieve electrical connections between components. During the manufacturing process of a PCB, hardness testing is required.

[0003] A hardness testing device for printed circuit board (PCB) processing (authorization announcement number: CN220040114U) is available. It uses a hydraulic cylinder to drive a stamping block to press the PCB, and then a detector on the stamping block performs the test. This allows for the adjustment and clamping of PCBs of different specifications during the pressing test. However, when testing the hardness of multilayer PCBs, which are composed of multiple insulating substrates and copper foil laminated together, thickness tolerances or uneven stress distribution between layers may exist. To ensure the accuracy of hardness testing, double-sided hardness testing is required. However, this hardness testing device requires releasing the clamped multilayer board and flipping it over after testing one side of the PCB, then re-clamping it to test the other side. This operation is inconvenient and cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hardness testing device for PCB circuit board processing, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hardness testing device for PCB circuit board processing includes:

[0007] The support frame has circular grooves on both inner walls.

[0008] The flipping component is rotatably mounted in two circular grooves of the support frame, and the flipping component can be flipped and adjusted.

[0009] The clamping component is located inside the flipping component. The clamping component can clamp and fix the multi-layer PCB circuit board placed inside the flipping component, which facilitates the hardness testing of the multi-layer PCB circuit board.

[0010] A plug-in limiting component is provided on one side of the support frame. The plug-in limiting component can limit and fix the position of the flipping component. The plug-in limiting component is configured to disengage from the flipping component when stretched outward, at which time the flipping component can be flipped and adjusted.

[0011] Preferably, the flipping component includes:

[0012] Two circular plates are rotatably mounted in corresponding circular grooves on the inner walls of both sides of the support frame, and the circular plates have positioning holes.

[0013] The frame is fixedly installed between two circular plates. The inner walls on both sides of the frame have sliding grooves, and the outer walls on both sides of the frame have an arc-shaped structure.

[0014] Preferably, the clamping assembly includes:

[0015] Two clamping frames, both ends of which are slidably installed in the grooves on the inner walls of the two sides of the frame;

[0016] A two-way threaded rod, one end of which is rotatably mounted on the inner wall of the corresponding slide groove on the frame, and the other end of which is threaded through the outside of the two clamping frames and extends to the outside of the frame and is fitted with a rod disc;

[0017] The guide rod has its two ends fixedly installed in corresponding grooves on the frame, and the guide rod is slidably connected to the two clamping frames.

[0018] Preferably, one side of the outer wall of the frame has a side opening, and the rod plate is located inside the side opening.

[0019] Preferably, the clamping frame has a frame groove, and the inner wall of the frame groove is provided with a rubber layer.

[0020] Preferably, the insertion limiting component includes:

[0021] The side panel is fitted onto the curved outer wall of one side of the frame.

[0022] Two positioning rods, one end of each positioning rod is fixedly installed on one side of the side plate, and the other end of each positioning rod extends into the corresponding circular groove on the support frame and is movably inserted into the positioning hole of the corresponding circular plate.

[0023] Two springs, both ends of which are fixedly installed on one side of the side plate, and the other end of which are fixedly installed on the outer side wall of the support frame;

[0024] The handle is fixedly installed on one side of the side panel.

[0025] Preferably, an mounting plate is fixedly installed on the top inner wall of the support frame, a hydraulic rod is fixedly installed on the bottom side of the mounting plate, and a hardness detection head is fixedly installed at the output end of the hydraulic rod.

[0026] This application, by adjusting the clamping assembly, can clamp and fix a multilayer PCB circuit board within the frame slots of two clamping frames. It can drive a hydraulic rod to move a hardness testing head downwards to perform hardness testing on one side of the multilayer PCB circuit board. When it is necessary to perform hardness testing on the other side of the multilayer PCB circuit board, the insertion limiting assembly is adjusted and stretched outwards. At this time, the clamped multilayer PCB circuit board can be flipped over by the flipping assembly. Then, the insertion limiting assembly is released, which can limit and fix the position of the clamped multilayer PCB circuit board within the frame after flipping, thus avoiding the need to release the clamped multilayer PCB circuit board. The operation is simple and quick. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To address the problem that performing hardness testing on one side of a multilayer PCB requires first loosening the clamped multilayer board, then flipping it over, and then re-clamping it to test the other side, which is inconvenient and cumbersome, this embodiment discloses a hardness testing device for PCB processing, including as follows: Figure 1 The support frame 100 shown; as Figure 4 The flipping component 200, clamping component 300, and insertion limiting component 400 are shown.

[0035] like Figure 3 and Figure 4 As shown, in order to install the flipping assembly 200, circular grooves 101 are provided on both inner walls of the support frame 100. The flipping assembly 200 is rotatably installed in the two circular grooves 101 of the support frame 100, and the flipping assembly 200 can be flipped and adjusted. The flipping assembly 200 includes: two circular plates 201 and a frame 202. The two circular plates 201 are respectively rotatably installed in the corresponding circular grooves 101 on both inner walls of the support frame 100, and the frame 202 is fixedly installed between the two circular plates 201.

[0036] like Figure 4 As shown, for the installation of the clamping assembly 300, both inner walls of the frame 202 have grooves 2021, and the clamping assembly 300 is disposed within the grooves 2021 on both inner walls of the frame 202. The clamping assembly 300 includes: two clamping frames 301, a bidirectional threaded rod 302, and a guide rod 303. Both ends of the two clamping frames 301 are slidably installed within the grooves 2021 on both inner walls of the frame 202. The clamping frames 301 have frame grooves, and the inner walls of the frame grooves are provided with rubber layers 3011. One end of the bidirectional threaded rod 302 is rotatably installed on the inner wall of the corresponding groove 2021 on the frame 202, and its other end is threaded through the outside of the two clamping frames 301 and extends to the outside of the frame 202, where a rod disc 3021 is installed. One side of the outer wall has a side opening 2022, and the rod plate 3021 is located inside the side opening 2022. The two ends of the guide rod 303 are fixedly installed in the corresponding sliding grooves 2021 on the frame 202. The guide rod 303 is slidably connected to the two clamping frames 301. When the rod plate 3021 at one end of the bidirectional threaded rod 302 is screwed, the bidirectional threaded rod 302 is driven to rotate. Under the guidance of the guide rod 303, the two clamping frames 301 slide in opposite directions in the sliding grooves 2021 on both sides of the inner wall of the frame 202, thereby clamping and fixing the multilayer PCB circuit board in the frame grooves of the two clamping frames 301. The rubber layer 3011 in the frame grooves of the two clamping frames 301 can play a clamping and protective role for the multilayer PCB circuit board.

[0037] Continue as Figure 4As shown, the insertion limiting component 400 is disposed on one side of the support frame 100. The insertion limiting component 400 can limit and fix the position of the flipping component 200. The insertion limiting component 400 is configured to disengage from the flipping component 200 when stretched outwards, at which point the flipping component 200 can be flipped for adjustment. The insertion limiting component 400 includes: a side plate 401, two positioning rods 402, two springs 403, and a handle 404. To facilitate the use of the side plate 401... For installation, the outer walls of both sides of the frame 202 are arc-shaped, and the side plate 401 is rotatably fitted onto one side of the arc-shaped outer wall of the frame 202. One end of each of the two positioning rods 402 is fixedly installed on one side of the side plate 401. The circular plate 201 has positioning holes 2011, and the other ends of the two positioning rods 402 extend into the corresponding circular grooves 101 on the support frame 100 and are respectively movably inserted into the positioning holes 2011 of the corresponding circular plates 201. At this time, the two... The position of the inner circular plate 201 in the circular groove 101 is limited and fixed; both ends of the two springs 403 are fixedly installed on one side of the side plate 401, and the other ends are fixedly installed on the outer side wall of the support frame 100. The handle 404 is fixedly installed on one side of the side plate 401. When the inspector holds the handle 404 and pulls the side plate 401 outward, the two positioning rods 402 are simultaneously driven to disengage from the positioning holes 2011 of the corresponding circular plate 201. At this time, the two springs 403 are deformed and stretched under force. At this time, the multi-layer PCB circuit board clamped and fixed in the frame 202 can be flipped. After the multi-layer PCB circuit board is flipped, the handle 404 is released. Under the elastic force of the two springs 403, the two positioning rods 402 are reinserted into the positioning holes 2011 of the corresponding circular plate 201 after flipping, so that the position of the multi-layer PCB circuit board clamped and fixed in the frame 202 after flipping is limited and fixed.

[0038] like Figure 1 As shown, a mounting plate 102 is fixedly installed on the top inner wall of the support frame 100, and a hydraulic rod 103 is fixedly installed on the bottom side of the mounting plate 102. A hardness detection head 104 is fixedly installed at the output end of the hydraulic rod 103. By activating the hydraulic rod 103, the hardness detection head 104 can be driven downward to perform hardness detection on the multilayer PCB circuit board clamped and fixed in the flipped frame 202.
