It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1 to 6, the present utility model provides a high-precision circuit board hardness detection device 100, which comprises a workbench 10, a positioning frame 20, a pressing assembly 30, a bearing assembly 40 and an analysis control system (not shown), wherein the upper end of the workbench 10 is provided with a detection groove 11, the positioning frame 20 stands on the upper end of the workbench 10, the pressing assembly 30 is arranged on the positioning frame 20 and is positioned above the detection groove 11, the bearing assembly 40 is arranged in the detection groove 11, and the analysis control system is in signal connection with other components.

The bearing assembly 40 comprises a pressure sensor 41, a buffer spring 42 and a bearing plate 43, which are sequentially installed in the detection groove 11 from bottom to top, wherein the upper end of the bearing plate 43 is provided with a jogging groove 431, and the bearing plate 43 can be movably lifted along the detection groove 11. The carrying assembly 40 further includes a plurality of laser ranging receivers 44, and a plurality of the laser ranging receivers 44 are respectively mounted on two sides of the upper end of the carrying plate 43 and vertically correspond to the plurality of laser ranging transmitters 33.
The level bar 32 and the laser ranging emitter 33 thereon can be moved up and down under the driving of the pressing air bar 31, and when the pressing air bar 31 is just propped against the circuit board to be tested in the jogged groove 431, an initial distance value exists between the laser ranging emitter 33 and the laser ranging receiver 44. When the pressing air bar 31 continues to press down, the circuit board, the carrier plate 43 and the laser ranging receiver 44 thereon are also subjected to pressure drop, and the bottom end of the pressing air bar 31 abuts against the surface of the circuit board to cause micro deformation of the surface of the circuit board, and the distance between the laser ranging transmitter 33 and the laser ranging receiver 44 is also changed. As the pressing force of the pressing air bar 31 is larger, the deformation degree of the surface of the circuit board is larger, and the distance between the laser ranging transmitter 33 and the laser ranging receiver 44 is also larger. The deformation degree of the surface of the circuit board can be monitored and recorded in real time and corresponds to the received pressure value from the process that the pressing air rod 31 just abuts against the surface of the circuit board until the circuit board is crushed, and finally, the high-precision hardness value of the circuit board can be obtained after the data are counted and analyzed through the analysis and control system.
The positioning frame 20 includes two sets of vertical frames 21 and a transverse frame 22. The two sets of stand frames 21 are respectively erected on two sides of the workbench 10, and a first sliding groove 211 is formed in the inner side of the upper end of each stand frame 21. The two ends of the cross frame 22 are respectively engaged in the two first sliding grooves 211 and can slide back and forth along the first sliding grooves 211, the lower end of the cross frame 22 is further provided with a second sliding groove (not shown), and the upper end of the pressing air rod 31 is engaged in the second sliding groove and can slide left and right along the second sliding groove. The pressing assembly 30 movably clamped on the second chute can freely adjust the horizontal coordinate of the pressing assembly, so that the pressing assembly can be positioned at any point on the surface of the circuit board for pressing detection.
In this embodiment, the level bars 32 of the pressing assembly 30 are provided with two sets, the two sets of level bars 32 are integrally disposed at the lower part of the pressing air bar 31 in a cross shape, and the plurality of laser ranging transmitters 33 are respectively disposed at two ends of the two sets of level bars 32. The laser ranging receivers 44 are respectively installed on four sides of the upper end of the carrier plate 43 and vertically correspond to the laser ranging transmitters 33.

The bearing assembly 40 further comprises a splash cover 45, and the splash cover 45 comprises a fixed sleeve plate 451 and a movable clamping plate 452. The fixed sleeve plate 451 is fixedly covered on the bearing plate 43, the fixed sleeve plate 451 is also internally provided with a containing cavity 451a with openings at the upper end and the lower end, the movable clamping plate 452 is embedded in the containing cavity 451a and can horizontally slide, and the movable clamping plate 452 is also provided with a pressing through hole 452a penetrating up and down. The splash guard 45 can cover and cover the circuit board in the embedded groove 431 completely, and fragments possibly generated after the circuit board is crushed can not escape from the embedded groove 431 to fly out under the blocking of the splash guard 45, so that potential safety hazards or cleaning problems are avoided. And the movable clamping plate 452 which can slide horizontally in the splash cover 45 can be matched with the up-and-down positioning of the pressing assembly 30, so that any point on the surface of the circuit board can be ensured to be subjected to hardness test.
The detection groove 11 is also internally provided with a plurality of lifting slide bars 12, a plurality of lifting slide holes 432 are respectively arranged on the bearing plate 43 and the splash cover 45, and the lifting slide holes 432 are respectively sleeved on the lifting slide bars 12. The lifting slide rod 12 can ensure that the bearing plate 43 and the splash cover 45 are always kept in a horizontal state in the lifting process, so that the situation that the bearing plate 43 and the splash cover 45 are inclined and cannot be perpendicular to the force application direction of the pressing assembly 30 is avoided, and finally the accuracy of hardness detection is influenced.
In operation, the circuit board is first fitted into the fitting groove 431 of the carrier plate 43 and covered and fixed by the splash guard 45. Then, the upper and lower positions of the pressing assembly 30 and the movable clamping plate 452 are adjusted to align the two with the detection points on the surface of the circuit, and the laser ranging transmitter 33 on the level bar 32 is adjusted to be aligned with the laser ranging receiver 44 below. The pressing assembly 30 is then started to press down, and data, including various sets of laser ranging data and pressure data of the pressure sensor 41, begin to be recorded when the bottommost end of the pressing air bar 31 is just in contact with the surface of the circuit board.
If the values of the laser ranging data of each group are similar, the pressure applied by the pressing air rod 31 is considered to be vertical to the surface of the circuit board; if the difference between the laser ranging data is too large, the pressure applied by the pressing air bar 31 is considered to be deflected, and the carrier plate 43 and the pressing assembly 30 need to be horizontally aligned. The recorded change value of the continuous laser ranging data corresponds to the continuous pressure change value of the synchronously recorded pressure sensor 41, and the analysis control system can analyze and obtain the high-precision circuit board hardness value from the two groups of data.
In summary, the high-precision circuit board hardness detection device 100 of the present utility model has the following advantages: the laser ranging transmitters 33 and the laser ranging receivers 44 are respectively arranged on the pressing assembly 30 and the bearing assembly 40, so that the deformation degree of the pressed surface of the circuit board is monitored in real time through high-precision laser ranging, and the hardness value of the circuit board obtained through analysis and detection has higher precision; the positioning frame 20 is provided with a first chute 211 and a second chute, so that the pressing assembly 30 can vertically and horizontally slide, and any point on the surface of the circuit board is positioned and detected; the splash cover plate 45 can cover and fix the circuit board, so that potential safety hazards or cleaning problems caused by splashing of broken fragments of the circuit board in the pressing process are avoided; the utility model has strong practicability and has stronger popularization significance.
