Description

A kind of clamping device that is applied to the measurement of SMT web plate
Technical field
The utility model relates to SMT equipment application, is specifically related to a kind of stationary installation that clamps.
Background technology
In the SMT field, the measurement of supplied materials web plate is become the critical process of guaranteeing SMT following process quality.SMT supplied materials web plate since thickness generally below 0.3mm, breadth is usually more than 400mmx400mm, this web plate has all that material is thin, characteristics such as precision is high, breadth is big, high flexibility.Along with the requirement of market to SMT web plate working (machining) efficiency and cost improves gradually, the breadth of SMT web plate is increasing.
In the past in the SMT web plate measuring equipment; Often directly web plate is placed on the measuring equipment platform; As shown in Figure 1, utilize measuring equipment platform 5 flatnesses own to guarantee that web plate 6 is placed on the flatness on this platform 5, utilize vertical gauge head 7 to carry out the measurement of web plate thickness or flatness again.The above-mentioned measuring equipment calibrated bolck that first certain thickness is A when measuring is placed on the measuring table 5 under the vertical gauge head 7, and getting measured value is h1, and this value is set at zero reference.Again calibrated bolck is taken away; Web plate 6 manually is placed on the measuring table 5; Hand drags web plate 6 moves to needs measurement arbitrarily on the web plate 6 position, web plate 6 is placed on the platform 5 sets level, and lets vertical gauge head 7 measure these points of web plate; Measured value is Y, calculates the thickness X=A-Y that can get final web plate through controller.
This method can be carried out measuring operation owing to require web plate 6 frequently on measuring table 5, to drag; Web plate 6 can be easy in the process measuring table 5 surface tears frequently dragging; And then influence web plate 6 and be placed on the formation state on the measuring table 5, thereby influence final measuring accuracy.Web plate 6 is owing to have higher flexibility in addition, and local meeting produces slight curves or distortion, and these bendings or distortion will cause Y value measuring accuracy not high equally, and the duplicate measurements precision is difficult to guarantee.
200810021712 disclose a kind of SMT of being used for web plate clamping and fixing locating device and localization method thereof; This method adopts three steel ball together support measurement point web plates that place same plane and be in contact with one another; Guarantee that each steel ball only contacts with web plate through peak; The point that contacts with web plate separately through three steel balls like this constitutes a three-point fix face, through the web plate in this planar support measured zone.After having supported the measured zone web plate; Utilization is uniformly distributed in the peripheral adsorption hole of three steel balls and adopts vacuum adsorption principle that the measured zone web plate is fixed on the measuring table, also guarantee simultaneously web plate in the measured zone fully with locating surface on three peaks fully contact.At last through vertical gauge head measurement and positioning face central spot web plate thickness.According to the open method of this patent,, need guarantee in advance: 1) three diameter of the steel ball unanimities in order to let web plate all touch better by these 3 locating surfaces that constitute; 2) three steel balls need to set level fully at grade (promptly guaranteeing the complete level of locating surface that three peaks constitute); 3) three peak formation locating surfaces will be a little more than the measuring table plane;
This method attempts to come the measured zone web plate is accurately located through the three-point fix principle, carries out thickness measure again.There is following defective in this method: 1) because locating surface relative measurement platform is slightly high; And adsorption hole is distributed on the peripheral measurement plane of locating surface; And web plate has higher flexibility, must cause the measurement point web plate to arch upward after the absorption, and the risk that causes web plate local deformation is arranged; 2) height that arched upward of different-thickness web plate is difficult to accurate control, has a strong impact on the duplicate measurements precision; 3) three steel balls are difficult to guarantee constitute the complete level of locating surface (and this face need to move up and down direction vertical with gauge head) by peak separately; 4) three steel ball precision are proposed very high request, the whole cost of experimental program is high, operation inconvenience.
