Now by reference to the accompanying drawings, brief description is carried out to pcb board erecting device, wherein, pcb board erecting device is used to installation pcb board, because the size of various electric energy meter pcb board is different, and the height of components and parts such as resistance, electric capacity is above also unequal, and positional alignment is also different, so, can not directly electric energy meter pcb board be placed on objective table; In addition, electric energy meter pcb board is transported on objective table by belt conveyor, and erecting device can install the pcb board of different size, and can carry on belt conveyor.
The installation method of described pcb board erecting device is as follows:
Pcb board is placed on long backstay 2, short backstay 5 by the pilot hole on it, and short backstay 5 is connected by screw thread with adjustment sheet 3; Adjustment sheet 3 is placed on support bar 4 and 6, and adjustment sheet 3 has elongated slot, can adjust distance; Base plate 1 there are 10 row * 10 row diameters be the threaded hole of 5mm, are used for long backstay 2 and support bar 4 and 6 are installed.Gib block 7 when pcb board erecting device is transported to detection platform for ensureing proper exercise direction.
Pcb board erecting device provided by the invention can lay the pcb board of different size size, makes system have more versatility, realizes the put correctly of PCB.
Embodiment three
Referring to Fig. 5, on the basis of the embodiment provided in the invention described above, preferably, also comprising the magnetic clamping device for clamping pcb board to be detected.
After inventor considers that pcb board is transported to objective table by erecting device, motion locating platform will move to the position of detection, in addition, in testing process, objective table also will rotate and swing, so pcb board erecting device needs to keep motionless on objective table, namely needs clamping.
Clamping mode mainly contain manually, air pressure, hydraulic pressure, electronic, electromagnetism, magnetic force, pull of vacuum etc.Along with developing rapidly of machine building industry, the popularization of automated and semi-automatic equipment, and in production in enormous quantities, require the labour intensity as far as possible alleviating operating personnel, the clampings such as most employing is now pneumatic, hydraulic pressure replace manpower to clamp, this kind of clamp system can also carry out far distance controlled, its clamping force can keep stable, and mechanism also need not consider self-locking, and clamping quality is also higher.
Now various clamping mode is simply introduced:
1, manual
Select the clamp device of manual mode must have reliable self-locking property and less primary action power, so hand actuable clamping device is used for the clamp device of bolt and nut force application mechanism and eccentric force application mechanism.When designing this clamp device, should consider that the fluctuation of operator's muscle power and mood is on the impact of the large minor swing of clamping force.
2, pneumatic
The power source medium of pneumatic mode is air, so undergo no deterioration and do not produce pollution, and the pressure loss is in the duct little, but air pressure is lower, be generally 0.4 ~ 0.6MPa, when needing larger clamping force, cylinder will be very large, cause clamp device structure not compact.In addition, because the compressibility of air is large, so the rigidity of clamp device and less stable.In addition, larger exhaust noise is also had.
3, hydraulic pressure
Hydraulic clamp utilizes hydraulic oil to carry out a kind of device of power transmission for actuating medium.It and pneumatic pinch Method compare, Hydraulic Clamping Mechanism has that pressure is large, volume is little, compact conformation, clamping force are stablized, vibration absorption ability by force, by the advantage such as impact of external force change.But complicated structure, manufacturing cost are higher, be therefore only applicable to a large amount of production.The kinematic train of hydraulic clamp and Normal hydraulic system class seemingly, but standingly in system have accumulator, in order to save pressure oil, to improve the service efficiency of hydraulic pump motor.After Workpiece clamping, hydraulic pump motor can quit work, and compensates leakage of oil by accumulator, keeps clamped condition.
4, solution-air combination
The power source of solution-air combination clamp device is pressurized air, but will use special supercharger, more complicated than air clamper.
5, electric electromagnetic
Electric wrench and magnechuck all belong to hardware features power source, electric wrench is often adopted to replace manually, not only enhancing productivity in processing line, and the fluctuation exerted a force when overcoming manual, and alleviate the labour intensity of workman, be obtain one of method stablizing clamping force.
6, magnetic force
Magnetic clamping device utilizes high performance magnet material, and suction is large, and volume is little, from heavy and light, and easy-to-operate.Owing to not needing power supply, the one-piece construction of magnetic clamping device is simple.
When designing clamp device, except the clamping mode that consideration adopts, also to consider the economic benefit used, the investment of power source facility not only should be made to reduce, and clamping structure should be made to simplify, reduce costs.According to above analysis, in conjunction with specific requirement, this project adopts magnetic clamping device.As shown in Figure 5, principle of work is as follows for its structure:
Pcb board erecting device delivers to objective table 1 by conveyor, in motion process, along two pieces of position orienting lugs 6 and 9, gradually from left to right, is tightly held by strong magnets 5.Position orienting lug 6 is connected on the platform 1 by socket head cap screw 7,8 with 10,11 with 9 respectively, and magnetic strips 5 is bonded on block 2, and block 2 is connected on objective table 1 by socket head cap screw 3,4.
Preferably, described conveyer is the light-duty fixed belt conveyor of U-shaped belt conveyor, tubular belt conveyor, air-cushion type belt conveyor, rope-driven conveyor, press belt type belt conveyor or QD80.
Preferably, described five shaft moving devices comprise:
The electric signal produced according to described controller is converted to the stepper motor of angular displacement.
In sum: five axle setting movement systems provided by the invention, the driving shaft be arranged in cabinet by driven by servomotor makes it by certain displacement at X, Y and Z axis move, and carry out at a certain angle horizontally rotating and special angle change plateau levels angle (angle of depression/elevation angle).Except this, high-speed CCD can be adopted to make a video recording to the electric energy meter PCB on driving shaft platform and carry out post processing of image, and the components and parts on plate are positioned and identified.The Sample Storehouse of Criterion pcb board, then compares analysis by the PCB to be measured gathered and standard sample database, realizes defects detection and components and parts detection and localization.The Identify chip in front plate can be realized and from the side components and parts are detected.Effectively solve the restriction by own physiological factor in prior art, manual detection mode efficiency is low, loss is high, subjectivity is strong, be subject to external interference, is difficult to meet the testing requirement that PCB components and parts are accurate, reliable, repeatability is high.
In this instructions, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.For the device that embodiment provides, the method provided due to itself and embodiment is corresponding, so description is fairly simple, relevant part illustrates see method part.
To the above-mentioned explanation of provided embodiment, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle provided in this article and features of novelty.
