Abstract
The utility model relates to a correct alignment detection device for a PCB. The device comprises a jig needle bed, positioning columns, cylinders and magnetic switches, wherein the positioning columns are cylindrical and respectively located at predetermined positions on the surface of the jig needle bed; the cylinders are located at edges of two sides of the jig needle bed; and the magnetic switches are connected with the cylinders. When the PCB is positioned, positioning holes of the PCB and the positioning columns are mutually matched, if the PCB fully drops into the positioning columns, the positioning is correct, and in the case of correct positioning, pistons of the cylinders can fully extend out. The device of the utility model can quickly detect whether the PCB is correctly positioned, accuracy of online detection is improved greatly, working performances of fully-automatic online detection or functional detection equipment can be effectively improved, a simple mechanical structure is adopted, the corresponding position of each part is easily adjusted, adaptability is wide, and the production cost is effectively reduced.
Description
Technical field
The utility model relates to fully-automatic equipment field, more precisely relates to the correct alignment detection apparatus of a kind of PCB.
Background technology
In full-automatic on-line testing or functional test equipment, owing to being unattended, how the correct location of detection line plate on fixture needle-bar becomes most important, reference column on pilot hole on PCB and fixture needle-bar cooperatively interacts under normal circumstances, it is tram that PCB falls into reference column completely, PCB alignment detection apparatus in the market adopts optical sensor or mechanical sensing device to position more, due to complicated in mechanical structure, be not easy to adjust, accuracy rate is lower, and production cost is also higher.
As can be seen here, current still Shortcomings of PCB alignment detection apparatus, exists and promotes improved space.
In view of the deficiency of current PCB alignment detection apparatus existence, the design people is based on being engaged in this type of product design manufacture for many years, amass and have abundant professional knowledge and practical experience, consult pertinent literature and physical construction innovation example, actively innovation research in addition, to designing a kind of novel PC B alignment detection apparatus, can improve in the market common PCB alignment detection apparatus, make it have more competitiveness and practicality, through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model of true tool use value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcome the deficiency of current PCB alignment detection apparatus, and provide the correct alignment detection apparatus of a kind of PCB, the complicated in mechanical structure and the sensing device that have overcome current PCB alignment detection apparatus are not easy the deficiency of adjusting, adopt cylinder and the magnetic switch sensing device as contraposition, optimize mechanical mechanism, and then improved the serviceability of the correct alignment detection apparatus of PCB.
The utility model solves its technical problem underlying and is achieved through the following technical solutions, according to the correct alignment detection apparatus of PCB the utility model proposes, the correct alignment detection apparatus of PCB comprises fixture needle-bar, reference column, cylinder and magnetic switch, fixture needle-bar is plane, reference column is cylindric and lays respectively at the precalculated position on fixture needle-bar surface, cylinder is positioned at the both sides of the edge of fixture needle-bar, magnetic switch and cylinder link together, in the time that PCB is positioned, pilot hole and the reference column of PCB cooperatively interact, it is correct location that PCB falls into reference column completely, , the piston of cylinder can stretch out completely when correct the location, piston stretches out stroke can just trigger magnetic switch, now state is correct location, when location of mistake, PCB cannot fall into reference column and the capital that is positioned rises, produce difference in height, the piston that stops cylinder stretches out, throw of poston cannot trigger magnetic switch, now state is location of mistake.
The correct alignment detection apparatus of PCB described in the utility model, the beneficial effect of its generation is: adopt cylinder and magnetic switch to be positioned at the structure of the both sides of the edge of fixture needle-bar, cylinder stretching out stroke and can just trigger magnetic switch in the time of the correct contraposition of PCB, whether can fast detecting go out PCB is properly oriented, greatly improve the accuracy rate of on-line testing, effectively improved the serviceability of full-automatic on-line testing or functional test equipment; Adopt simple physical construction, the relative position of each several part is easily adjusted, and adaptability is extensive, has effectively reduced production cost.
Accompanying drawing explanation
Fig. 1 is the vertical view of embodiment of the present utility model.
Description of reference numerals: 1, fixture needle-bar; 2, reference column; 3, cylinder; 4, magnetic switch.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment, structure, feature and effect thereof according to the utility model proposes, be described in detail as follows.
Refer to shown in Fig. 1, the correct alignment detection apparatus of PCB of the present utility model, the correct alignment detection apparatus of PCB comprises fixture needle-bar 1, reference column 2, cylinder 3 and magnetic switch 4, fixture needle-bar 1 is plane, reference column 2 is cylindric and lays respectively at the precalculated position on fixture needle-bar 2 surfaces, cylinder 3 is positioned at the both sides of the edge of fixture needle-bar 1, magnetic switch 4 links together with cylinder 3, in the time that PCB is positioned, the pilot hole of PCB and reference column 2 cooperatively interact, it is correct location that PCB falls into 2 of reference columns completely, , the piston of cylinder 3 can stretch out completely when correct the location, piston stretches out stroke can just trigger magnetic switch 4, now state is correct location, when location of mistake, PCB cannot fall into reference column 2 and post 2 jack-up that are positioned, produce difference in height, the piston that stops cylinder 3 stretches out, throw of poston cannot trigger magnetic switch 4, now state is location of mistake.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong to the scope of technical solutions of the utility model.
