Description
Technical field
This utility model relates to pcb board technical field of measurement and test, particularly relates to a kind of device for automatically testing pcb board thickness.
Background technology
Pcb board Chinese is printed circuit board, also known as printed substrate, is the supplier of electronic devices and components electrical equipment connection, is also a kind of important electronic unit, or the support member of electronic devices and components.Owing to it is to adopt electron printing to make, therefore it is called " printing " circuit board.Wherein, welding electronic component on pcb board is needed in actual production is processed, thus the thickness of pcb board is just varied from, and in order to be suitable for the use of manufactured product, need the thickness of whole pcb board is detected, guarantee that pcb board thickness is consistent with designing requirement scope, duty can be entered.Prior art also has the device quickly detecting pcb board thickness, a kind of pcb board thickness measuring tool as disclosed in State Intellectual Property Office, application number is 201210552858X, publication No. is CN103047921A, this measurement jig includes testboard, strip gab, movable plate and cylinder, movable plate is provided with the circular open relative with strip gab position, cylinder piston boom end is connected to insertion plate, described insertion plate can be sequentially inserted into strip gab and circular open, and can slide along strip gab, at testboard top, dividing plate is set, the space for testing pcb board thickness is left between dividing plate and testboard.The device of the disclosure can pass through the sample that spacers block pcb board thickness is excessive, but owing to the gap width on this dividing plate is invariable, so the sample that pcb board thickness is too small can not be identified, namely the test device of the disclosure can not identify the lower range of pcb board；Also the sample so that not being welded with electronic devices and components on pcb board it is possible to by this dividing plate.In the actual production course of processing, it is necessary to identify that pcb board is in acceptability limit and can dispatch from the factory, so the test apparatus function of the disclosure is excessively single, it is impossible to whether enough fast and effeciently identification pcb board samples meet designing requirement.
Utility model content
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, it is provided that a kind of device for automatically testing pcb board thickness that can fast and effeciently identify whether pcb board sample meets designing requirement.
Technical solution of the present utility model is, there is provided a kind of device for automatically testing pcb board thickness with following structure: include pedestal and slide plate, slide plate is slidably connected on pedestal by dovetail groove, slide plate is provided with linear gear rack, pedestal is rotatably connected to for the gear with linear gear rack engaged transmission, and pedestal is provided with the motor for driving gear rotating to move back and forth to drive slide plate；Described slide plate is provided with multiple skewback, and multiple skewbacks are spaced apart along slide plate length direction, and forms the storage tank for placing pcb board between adjacent two skewbacks, and skewback upper surface vertically arrives the distance H one-tenth-value thickness 1/10 more than pcb board of storage tank bottom surface；Described pedestal is connected to guide pin bushing by frame, slidably connects montant in guide pin bushing, and montant lower end is provided with the flat board for pushing against with skewback and pcb board, and montant upper end is provided with thimble, and is provided with the first stage clip between flat board and guide pin bushing；Described frame is provided with rule, and thimble is provided with the prong structure of rule scale zone, and frame is provided with the prong structure for amplifying on thimble and points to the magnifier in rule high scale region；Described slide plate is provided with the open slot for placing pcb board, and open slot is provided with breach, slidably connects push rod in breach, is provided with for promoting the push rod slip the second stage clip so that pcb board to be pushed against open slot edge between push rod and breach.
Pcb board is placed in the open slot on slide plate by operator of the present utility model one by one, driven by motor slide plate moves ahead to deliver to immediately below flat board the pcb board in open slot one by one, owing to skewback is higher than pcb board, so flat board can decline to be resisted against pcb board upper surface under the first stage clip effect, thus the thimble of montant upper end also can decline along vertical direction and drive prong structure to decline, then prong structure will be subjected to displacement relative to rule, thus relative to the displacement of rule, operator just can judge whether the thickness of this collection of pcb board meets designing requirement according to prong structure；And, there is again the setting of open slot, so pcb board lower end just can be inlaid in open slot, thus flat board lower surface would not drive pcb board to slide in storage tank when rubbing relative to pcb board upper surface slide, namely pcb board is played the effect of a location by open slot so that whole detection process is more reliable and more stable.Additionally, can so that various sizes of pcb board is positioned at open slot by the setting of push rod and the second stage clip, and pcb board will not be subjected to displacement when following slide plate and moving ahead, and push rod and the second stage clip can continue to compress pcb board bottom.Therefore, this utility model provides a kind of device for automatically testing pcb board thickness that can fast and effeciently identify whether pcb board sample meets designing requirement.
Preferred as one, the first described compression spring sleeve is connected on montant, and the first stage clip upper end and guide pin bushing lower surface push against, and the first stage clip lower end and flat board upper surface push against.Preferred by this, the first stage clip can promote flat board to decline with guide pin bushing lower surface for benchmark, and enable to flat board and be resisted against all the time on skewback or pcb board.
Preferred as one, described montant is vertically slidably connected in guide pin bushing.Preferred by this, it can be ensured that the direction of motion of montant, it is to avoid sliding inclined phenomenon occurs montant.
Preferred as one, described thimble is perpendicular to montant axis and arranges.Preferred by this, it is possible to make the prong structure on thimble point to rule just over the ground.
Preferred as one, described flat board lower end is provided with fillet.Preferred by this, flat board lower edge margin contact of incline plane on skewback can be avoided to move interference when sliding, so that it is guaranteed that the inclined-plane on skewback can promote flat board to rise, and frictional force time slip in flat board lower end on skewback can also be reduced by this fillet design.
