Please refer to Fig. 1-shown in Figure 4, the manual SMT web plate of column of the present invention thickness measurement device includes base platform 1, is arranged at web plate clamping device 2 and column measuring mechanism 3 on the base platform 1.Wherein, described base platform 1 is used to carry web plate to be measured; Described column measuring mechanism 3 is installed on the base platform 1, and it includes column 30, automatic Z axle 31 and vertical gauge head 32; Described automatic Z axle 30 directly is fixed on the column head, and vertical gauge head is fixed on the Z axle, thereby can accurately adapt to the thickness measure of different-thickness SMT supplied materials web plate.Adopt the base platform of natural granite in the embodiment of the invention, guarantee Stability Analysis of Structures as entire equipment; And adopt the precise vertical gauge head, and realize that by a micro servo motor this gauge head accurately moves up and down, to adapt to the thickness measure demand of different-thickness SMT supplied materials web plate.
Described web plate clamping device 2 includes the gib screw 20 that is used to be fixed on the base platform, adjust screw tap 22, vacuum absorbing platform 23, annular gas tank 24, be arranged at the suction hole 25 on the annular gas tank and the central suction hole 26 at setting and clamping device center.In addition, described web plate clamping device 2 also is provided with flexible hinge structure 27.
Wherein, described gib screw 20 by the screw on the vacuum absorbing platform 23 with on the clamping device 2 firm banking platforms 1, in embodiments of the present invention, totally four on described screw, described vacuum absorbing platform is symmetrically arranged with four screws.
The main part of described web plate clamping device 2 adopts No. 45 steel integral types to process, adopt accurate flexible hinge structure as the foundation structure that realizes that two dimension angular is adjusted, as shown in Figure 4, the flexible hinge place adopts heat treatment method to carry out modifier treatment, this is in keeps having good toughness under certain intensity situation.Described flexible hinge structure 27 includes two-layer, and is mutually vertical layout, is undertaken adjusting around X-axis with around the accurate angle two dimension of Y-axis by adjusting four screw taps respectively, and described four screw taps are respectively first, second, third, fourth screw tap 271-273; Wherein, these screw tap layouts as shown in Figure 2, first and second screw tap 271,272 is symmetricly set on the vacuum absorbing platform 23.
The process that described flexible hinge structure 27 is carried out the adjustment of angle two dimension is as follows: carry out around the X-axis angular setting, adjust first screw tap 271 respectively and adjust second screw tap 272, be specially slightly to unclamp and adjust first screw tap 271, tighten and adjust second screw tap 272, can realize the positive-angle adjustment; On the contrary, then realize the adjustment of dihedral degree.And carry out when the Y-axis angular setting, adjust the 3rd screw tap 273 and adjustment the 4th screw tap 274 respectively to get final product, be specially slightly to unclamp and adjust the 3rd screw tap 273, tighten and adjust the 4th screw tap 274, can realize the positive-angle adjustment; On the contrary, then realize the adjustment of dihedral degree.
The angle two-dimensional adjusting structure of described flexible hinge structure 27 is full decoupled structure, is adjusting when the X-axis angle is rotated, and opposing connection Y-axis angle is rotated without any influence, and vice versa, and the flexible hinge structure as shown in Figure 4.
Described clamping device 2 is adjusted the function except that having accurate angle two dimension, also has the vacuum suction function, adjust function by angle two dimension and will adjust to that to move up and down direction vertical with vertical gauge head, by the vacuum suction function web plate is adsorbed on again and carries out thickness measure on the clamping device again with the web plate binding face.The clamping device that has accurate two dimension angular adjustment function, vacuum suction function by employing comes the clamping web plate, it is vertical mutually to guarantee that fixing back of web plate and vertical gauge head move up and down direction, and guarantee the complete and clamping device workplace applying of SMT supplied materials web plate in measured zone, can not be difficult to problems such as control because of the inaccurate duplicate measurements precision that causes of fitting.Measure the whole zone of web plate and be held fully that mechanism is adsorbed lives, and with the web plate binding face be the Precision Machining face of flatness uniformity, measured zone does not have projection, and the absorption affinity to web plate in measured zone is a uniformity, does not have web plate part and the not tight problem of clamping device workplace applying in measured zone.
Please refer to shown in Figure 5, during application, earlier be that the calibrated bolck of A is placed on this clamping device workplace and adsorbs with thickness, measure the h1 value, this value is set at zero point, again calibrated bolck is removed, the SMT web plate is placed on the clamping device adsorbs, measure the Y value, thereby the thickness X that accurately obtains measured SMT web plate is A-Y.
The present invention creates and adopts column mode layout, utilizes the clamping device of adjustment of angle two dimension and vacuum suction function to fix web plate, and this clamping device is that integral type processes.Angle two dimension is adjusted function, and can to guarantee that measured zone web plate and vertical gauge head move up and down direction vertical mutually, with the assurance measuring accuracy; The vacuum suction function is guaranteed the SMT web plate in the measured zone fitted fully with clamping device fully and is integral, and can not cause the web plate distortion and web plate well can be fixed, and carries out the thickness measure of SMT web plate by vertical gauge head again.This equipment considers that the SMT industry only needs to carry out the characteristics of demand of thickness measure on some points to the supplied materials web plate, adopted the manual measurement mode to substitute automatic metering system, thereby removed complicated shafting structure, adopting vertical gauge head of high-performance and high-accuracy SMT web plate clamping device to guarantee under the measuring accuracy prerequisite, simplified apparatus system complex degree to greatest extent, reduce the device hardware cost, greatly adapted to of the actual demand of current and following SMT industry the web plate thickness measurement device.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
