Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-2, the pressing jig comprises a supporting plate 1, a supporting column i 2, a supporting column ii 3, a limiting block 4, a pressing block 5 and an element supporting block 6; the PCB laminating machine is characterized in that a limiting block 4 and an element supporting block 6 are connected to the supporting plate 1 through screws, corresponding through holes are preset in the supporting plate 1, the limiting block 4 and the element supporting block 6 are placed at corresponding positions, then screws penetrate through the through holes from the bottom of the supporting plate 1 to be in threaded connection with the limiting block 4 and the element supporting block 6, the number and the positions of the element supporting plates 6 are matched with those of elements needing to be laminated on a PCB, and when the PCB laminating machine is used, the limiting block 4 is matched with the edge of the PCB, so that the PCB cannot move in the laminating process; placing the element to be pressed on the bottom of the PCB on the element supporting block 6, then placing the PCB, pressing the PCB downwards with force, pressing the PCB to move downwards or deform, and pressing the upper pins of the element into the PCB and connecting the upper pins with the PCB; stopper 4 is the echelonment, and stopper 4 has 10, and wherein the left and right sides face is equipped with 3 respectively, and the front and back both sides have 2 respectively, and during the use, stopper 4 ladder department horizontal plane and PCB board bottom cooperate, support the border position of PCB board, and the PCB board can not move downwards all the time in the pressfitting in-process and crush bottom element on the PCB board, stopper 4 ladder department perpendicular and the marginal phase-match of PCB board, make the PCB board can not the horizontal migration in the pressfitting in-process. Be equipped with pin through-hole 7 on layer board 1, pin through-hole 7 suits with component pin position on the PCB board, and longer pin passes pin through-hole 7 at the pressfitting in-process, avoids the pin to touch layer board 1 and takes place to warp the damage.

Be equipped with support column I2 and support column II 3 that is used for supporting the PCB board on layer board 1, support column I2 and support column II 3 distribute at 1 middle part of layer board, and at pressfitting in-process support column I2 and II 3 up end support column PCB board bottom surfaces of support column, provide effective support for the middle part of PCB board, prevent that the PCB board from damaging at pressfitting in-process deflection is too big, be equipped with locating pin 8 on the support column II 3, 8 positions of locating pin and II 3 concentric settings of support column, locating pin 8 and II 3 integrated into one piece of support column, during the pressfitting, locating pin 8 passes and reserves the through-hole on the PCB board, it is further spacing to the position of PCB board, make the PCB board fix in.
