referring to fig. 8, 9 and 10, in a first comparative example, as another embodiment of the present invention, the upper surface of the cabinet body 1 is symmetrically provided with a sliding groove 33, a sliding plate 331 is provided in the sliding groove 33, the sliding plate 331 is fixedly connected to an end portion of the supporting column, both sides of the sliding groove 33 are provided with fixing holes 34, a rectangular groove 35 with a flat shape is provided on an outer side wall of the sliding plate 331, an extrusion rod 36 is provided in the rectangular groove 35, one end of the extrusion rod 36 is rotatably connected in the rectangular groove 35, a pull rope 37 is fixedly connected on a side wall of the extrusion rod 36, both side walls of the sliding plate 331 are provided with sliding holes, a spring connected fixing pin 38 is provided in the sliding holes, one end of the fixing pin 38 is fixedly connected with the pull rope 37, and the other end of the fixing pin 38 is embedded in the fixing hole 34; the adjustment of the space between the material plates 3 is realized by arranging the pressing modules which can relatively move, so that the method can be suitable for the strength detection of PCB plates with different thicknesses and different lengths; when the distance is adjusted, the outer ends of the extrusion rods 36 are inwards extruded by fingers to enable the two extrusion rods to be close to each other, at the moment, the extrusion rods 36 pull the pull ropes 37, the pull ropes 37 pull the fixing pins 38, the fixing pins 38 shrink into the sliding holes, and at the moment, the sliding plate 331 can be easily moved to adjust the distance between the two pressing modules.
The end of the extrusion rod 36 is arc-shaped and is oppositely and outwards turned; the configuration of the outer end shape of the extrusion rod 36 allows the finger portion to effectively grip the extrusion rod 36 when the extrusion rod 36 is being extruded inwardly, preventing the fingers from being separated from the outer end of the extrusion rod 36 when the extrusion rod 36 is being cleaned inwardly.
Working principle: placing two ends of a PCB (printed circuit board) on a material plate 3, then driving a first air cylinder 6, pressing a movable plate 4 downwards by a pressing plate 5, pressing springs downwards by two ends of the movable plate 4, simultaneously pressing the PCB, stabilizing the two ends of the PCB on the material plate 3, then driving a second air cylinder 7, pushing an ejector rod 8 on the second air cylinder 7, upwards pressing the ejector rod 8 on the PCB by the ejector rod 8, and realizing strength test of the PCB, wherein the two ends of the PCB are pressed downwards by the movable plate 4, so that the stability of the PCB can be ensured, and the strength detection of the PCB is realized; meanwhile, the pressing plate 5 can flexibly move up and down, so that the extrusion force of the movable plate 4 on the PCB is controlled, when the PCB is pushed up by the ejector rod 8, the two ends of the PCB can slide along the material plate 3, the two ends of the PCB can be ensured to be always placed on the material plate 3, and the two ends of the PCB are prevented from being separated from the material plate 3;
the thickness and the size of the PCB are various, and pressing plates 11 with different specifications are installed according to the size of the PCB to be detected, namely, the pressing plates 11 are connected in the limiting groove 10 in a sliding manner through the T-shaped plate 12, so that stacking of a plurality of pressing plates 11 is realized; because the movable plate 4 can not fix the two ends of the PCB, a movable space is reserved for the movement of the end parts of the PCB, otherwise, the PCB is pulled by force in the horizontal direction, and is not extruded and detected by force vertical to the PCB; for the slender PCB, the horizontal direction of the PCB is offset in the space, so that the extrusion force on the ejector rod 8 cannot be uniformly applied to the PCB, and therefore, the multistage grooves 9 are formed, the multistage grooves 9 are matched with the stacked pressing plates 11, the movement of the PCB can be limited, and the measurement accuracy is ensured;
by arranging the anti-slip strips 13, when the push rod 8 pushes up the PCB, the two ends of the PCB instantly slide away from the material plate 3; the anti-slip strips 13 are made of rubber materials, when the PCB is jacked, the two ends of the PCB are extruded to the pressing plates 11, resistance can be generated between the anti-slip strips 13 and the PCB, and the two ends of the PCB are prevented from sliding away, so that the two ends of the PCB slowly move, and the two ends of the PCB can be restrained by the parts;
when the PCB is pushed up by the ejector rod 8, the PCB deforms, meanwhile, at a position with larger curvature, the material breaks, the breaking degree of the material is fed back to a material department after collection, forward assistance can be provided for the material department, more problems are obtained, therefore, a picture capturing unit is arranged, the camera 18 rotates to the position on the PCB, which is upwards pushed by the ejector rod 8, of the PCB, the camera 18 can continuously and clearly capture broken pictures of the PCB, meanwhile, in order to improve the picture definition, a lamp body 19 is arranged on the board, the lamp body 19 can adopt energy-saving LED lamp beads for illumination, and the picture capturing unit is arranged on the pressing board 5 and moves along with the up-down movement of the pressing board 5, and the placement and the removal of the PCB are not hindered;
in the process of detecting the strength of the PCB, the push rod 8 extruded part on the PCB is bent, after the bending degree exceeds the limit of the PCB, the PCB is broken, and suddenly bursts and breaks, particularly, after the PCB is broken, some thicker plates can be seen to splash fragments of the PCB, and operators beside the camera 18 or are accidentally injured, therefore, the traction rope 23 is fixedly connected on the PCB, and the traction rope 23 binds the PCB, so that the splashing of fragments is reduced at the moment of bursting; in the inspection process, the third air cylinder 21 is driven, the lifting plate 22 is pushed upwards, the lifting plate 22 pulls the traction rope 23, the traction rope 23 pulls the PCB, the traction rope 23 is an elastic rope body, and the end part of the traction rope 23 is fixed on the surface of the PCB in a dendritic dispersion manner, so that more areas of the PCB can be cared, and the strength detection of the PCB cannot be influenced;
the two ends of the frame capturing unit are symmetrically provided and fixed on the pressing plate 5 in a magnet adsorption mode, namely, when the frame capturing unit is taken down, the fixing rod 14 and the magnet 26 are directly extracted from the notch 25, so that the frame capturing unit is modularized, and is easy to assemble and store;
because the specifications of the PCB plates are various, the lengths of the traction ropes 23 are different, after some traction ropes 23 are fixed on the PCB plates, the residual rope portions are left, the end parts of the traction ropes 23 penetrate through the window 24 and the through holes 27, then are embedded into the through holes 29 of the traction blocks 28, the residual rope portions are knotted and blocked at the upper ends of the holes 29, when the lifting plate 22 is lifted, the traction blocks 28 are extruded towards the directions of the through holes 27, the gaps 30 of the lower half outer rings of the traction blocks 28 are mutually closed, and meanwhile, the traction ropes 23 are extruded, so that the quick fixation of the traction ropes 23 is realized;
in the case of the through-hole 27 and the through-hole 29 having a smaller diameter of the transfer cord through-hole 29, it is difficult to open the inlet 31 at the middle side of the lifting plate 22 and the discharge hole 32 at the side of the pulling block 28, and the transfer cord 23 can be taken out by moving the transfer cord from the inlet 31 into the through-hole 27 and from the discharge hole 32 side into the through-hole 29 and moving the transfer cord 23 along the inlet 31 and the discharge hole 32 side after the knot of the pulling cord 23.
