Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to an automated and efficient PCB board testing fixture. Background Technology

[0002] Solder mask, as a protective layer on the surface of a PCB board, needs to cover the copper foil to prevent oxidation and corrosion. Insufficient abrasion resistance can lead to surface scratches, potentially exposing the copper foil and causing short circuits or poor contact, directly affecting circuit performance.

[0003] The abrasion resistance test of the solder mask on a PCB is mainly to ensure that it can resist physical wear under unexpected conditions, so as to ensure the stability and reliability of the circuit.

[0004] Currently, when conducting abrasion resistance tests on the solder mask layer on the surface of PCB boards, it is usually done manually by holding pencils of different hardness values ​​and scratching the solder mask layer on the PCB board surface in turn. This is to test at what hardness value of pencil scratching the solder mask layer on the PCB board surface can withstand without producing scratches, thereby judging the abrasion resistance of the PCB board. Since this method involves manually holding pencils of different hardness values ​​and scratching the solder mask layer on the PCB board surface, it has the disadvantages of low testing efficiency and inconvenience of operation, and therefore needs to be improved. Utility Model Content

[0005] This invention aims to provide an automated and efficient PCB board testing fixture to address the problem mentioned in the background art: when conducting abrasion resistance testing on the solder mask layer on the PCB board surface, it is usually done manually by holding pencils of different hardness values ​​and scratching the solder mask layer in sequence to determine the level of pencil hardness at which the solder mask layer can withstand scratching without producing marks, thereby judging the abrasion resistance of the PCB board. Because this method involves manually holding pencils of different hardness values ​​and scratching the solder mask layer on the PCB board surface, it suffers from low testing efficiency and inconvenience in operation.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: An automated and efficient PCB board testing fixture includes a support platform, a control panel, two linear modules a, and six testing components; the top of the support platform has a groove for accommodating the PCB board; the two linear modules a are respectively longitudinally arranged on both sides of the top of the support platform; the two linear modules a are connected to a horizontally oriented mounting plate; the six testing components are distributed at the front of the mounting plate and are all located above the groove; each of the six testing components has a linear module b, a fixing member, and a pencil; the linear module b is vertically arranged at the front of the mounting plate; the fixing member is located at the front of the linear module b; the fixing member contains a vertically oriented pencil; the pencils in the six testing components have different lead hardness values; the control panel is located on the support platform and is electrically connected to the two linear modules a and the six testing components.

[0007] In some embodiments, the lead hardness values ​​of each pencil in the six test components are H, 2H, 3H, 4H, 5H and 6H, respectively.

[0008] In some embodiments, the fastener includes a block and a hand screw. The block has a through hole extending vertically, into which a pencil is inserted. The block has a threaded hole on its side, one end of which communicates with the outside of the block, and the other end of which communicates with the through hole in the block. The hand screw is threaded into the threaded hole and abuts against the pencil in the through hole.

[0009] In some embodiments, the top of the support platform has a pinching groove located at the front of the recess.

[0010] In some embodiments, the control panel is provided with a display screen and several control buttons.

[0011] In some embodiments, both linear modules a are welded and fixed to the top of the support platform.

[0012] In some embodiments, all six test components are welded and fixed to the front of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when testing the abrasion resistance of the solder mask on a PCB board, the PCB board is placed in a groove on the top of a support platform. The groove blocks and limits the four sides of the PCB board. Then, the user controls the linear modules b in the six test components to simultaneously drive their connected pencils to move down and contact the surface of the PCB board in the groove via the control panel. Next, the user controls the two linear modules a to simultaneously drive the six test components on the mounting plate to move back and forth, so that the pencil leads in the six test components simultaneously scratch the surface of the PCB board. Since the pencil leads in the six test components have different hardness, the operator can determine which pencil hardness will leave scratches on the solder mask layer on the PCB board surface, and which pencil hardness will not leave scratches on the solder mask layer on the PCB board surface. Thus, the operator can test the abrasion resistance of the solder mask on the PCB board surface. In this invention, by setting up two linear modules a and six test components, multiple pencil leads with different hardness values ​​are used simultaneously to scratch the solder mask layer on the PCB board surface to test the wear resistance of the solder mask on the PCB board surface relative to different pencil hardnesses. Manufacturers can then use the tested wear resistance of the solder mask on the PCB board surface as a reference to control the production quality of the PCB board. This invention has the advantages of high testing efficiency and ease of use. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] Please refer to the following: Figures 1 to 5 As shown, Figure 1 A schematic diagram of the overall structure of an automated, high-efficiency PCB board testing fixture 100; Figure 2 A schematic diagram of the structure of an automated, high-efficiency PCB board testing fixture 100 with a PCB board 60 placed in it. Figure 3 A schematic diagram of the structure of six test components 50 mounted on the mounting plate 40; Figure 4 This is a schematic diagram of the structure of test component 50; Figure 5 This is a schematic diagram showing the structure with the fastener 502 and the pencil 503 in a separated state.

[0025] This utility model provides the following technical solution: an automated and efficient PCB board testing fixture 100, including a support platform 10, a control panel 20, two linear modules a30, and six testing components 50; the top of the support platform 10 has a groove 101 for accommodating the PCB board 60; the two linear modules a30 are respectively longitudinally arranged on both sides of the top of the support platform 10; the two linear modules a30 are connected to a horizontally oriented mounting plate 40; the six testing components 50 are distributed at the front of the mounting plate 40 and are evenly distributed... The corresponding positions are located above the groove 101; each of the six test components 50 has a linear module b501, a fixing member 502, and a pencil 503. The linear module b501 is vertically arranged at the front of the mounting plate 40, and the fixing member 502 is arranged at the front of the linear module b501. A vertically arranged pencil 503 is installed in the fixing member 502. The lead hardness value of each pencil 503 in the six test components 50 is different; the control panel 20 is arranged on the support platform 10 and is electrically connected to the two linear modules a30 and the six test components 50 respectively.

[0026] In the automated and efficient PCB board testing fixture 100 provided in this embodiment, when testing the abrasion resistance of the solder mask on the surface of the PCB board 60, the PCB board 60 is placed in the groove 101 on the top of the support platform 10. The groove 101 blocks and limits the four sides of the PCB board 60. Then, the user controls each linear module b501 in the six test components 50 to move simultaneously and drive the pencil 503 connected to it to move down and contact the surface of the PCB board 60 in the groove 101 through the operation control panel 20. Then, the user controls two sets of linear modules a30 to move simultaneously to jointly drive the mounting plate. The six test components 50 on the 40 move back and forth so that the pencil leads of each pencil 503 in the six test components 50 simultaneously scratch the surface of the PCB board 60. Since the pencil leads of the six test components 503 have different hardness, the operator can determine which pencil lead of different hardness values ​​will leave scratches on the solder mask layer on the surface of the PCB board 60, and which pencil lead of different hardness values ​​will not leave scratches on the solder mask layer on the surface of the PCB board 60. Thus, the operator can test the wear resistance of the solder mask on the surface of the PCB board 60. In this invention, by setting up two linear modules a30 and six test components 50 in cooperation, multiple pencil leads 503 with different hardness values ​​are used simultaneously to scratch the solder mask layer on the surface of the PCB board 60 to test the wear resistance of the solder mask on the surface of the PCB board 60 relative to different pencil hardnesses. Manufacturers can then use the tested wear resistance of the solder mask on the surface of the PCB board 60 as a reference to control the production quality of the PCB board 60. This invention has the advantages of high testing efficiency and ease of use.

[0027] In some embodiments, the lead hardness values ​​of each pencil 503 in the six test components 50 are H, 2H, 3H, 4H, 5H and 6H, respectively.

[0028] In specific implementation: the lead hardness values ​​of each pencil 503 in the six test components 50 are H, 2H, 3H, 4H, 5H, and 6H, respectively. Therefore, when pencils with hardness values ​​of H, 2H, 3H, 4H, 5H, and 6H are simultaneously used to scratch the solder mask on the surface of the PCB board 60, the hardness values ​​of the pencils with hardness values ​​of H and 2H will be significantly reduced. The test aims to determine which of the following pencil leads—those with hardness values ​​of 3H, 4H, 5H, and 6H—will scratch the solder resist layer on the surface of PCB board 60, and which will not. This allows staff to effectively test the abrasion resistance of the solder resist layer on the surface of PCB board 60 relative to the scratches from pencil leads of different hardness values.

[0029] In some embodiments, the fastener 502 includes a block 5021 and a thumbscrew 5022. The block 5021 has a through hole 50211 extending vertically through it. A pencil 503 is inserted into the through hole 50211. A threaded hole 50212 is provided on the side of the block 5021. One end of the threaded hole 50212 communicates with the outside of the block 5021, and the other end of the threaded hole 50212 communicates with the through hole 50211 in the block 5021. The thumbscrew 5022 is threaded into the threaded hole 50212 and abuts against the pencil 503 in the through hole 50211.

[0030] In practice: When fixing the pencil 503 to the fastener 502 on the linear module b501, the pencil 503 can be inserted into the insertion hole 50211 of the block 5021. Then, the hand-tightening screw 5022 is threaded into the threaded hole 50212 and pressed against the pencil 503 in the insertion hole 50211, thereby fixing the pencil 503 in the insertion hole 50211 of the block 5021, and thus fixing the pencil 503 to the fastener 502 on the linear module b501. When it is necessary to replace the pencil 503 fixed in the fastener 502, the hand-tightening screw 5022 can be unscrewed from the threaded hole 50212, thereby releasing the hand-tightening screw 5022 from the pencil 503 inserted into the insertion hole 50211 of the block 5021, and then the pencil 503 can be removed.

[0031] In some embodiments, the top of the support platform 10 has a pinch groove 102 at the front of the groove 101.

[0032] In specific implementation: when the user places the PCB board 60 into the groove 101 or removes the PCB board 60 from the groove 101, the gripping groove 102 is used to provide the user's hand with room to move so that the PCB board 60 can be manually placed into the groove 101 or manually removed from the groove 101.

[0033] In some embodiments, the control panel 20 is provided with a display screen 201 and a plurality of control buttons 202.

[0034] In practice: the display screen 201 on the control panel 20 is used to display the running status of the automated high-efficiency PCB board testing fixture 100. The control buttons 202 on the control panel 20 are used by the user to manually press them, thereby issuing execution commands to the control panel 20 so that the control panel 20 can execute the corresponding operation of the two linear modules a30 and the six test components 50.

[0035] In some embodiments, both linear modules a30 are welded and fixed to the top of the support platform 10.

[0036] In practice: both linear modules a30 are welded and fixed to the top of the support platform 10 so that the two linear modules a30 can be stably installed on the top of the support platform 10 for application.

[0037] In some embodiments, all six test components 50 are welded and fixed to the front of the mounting plate 40.

[0038] In practice: all six test components 50 are welded and fixed to the front of the mounting plate 40 so that the six test components 50 can be stably installed on the mounting plate 40 for application.
