Description
Technical field
The present invention relates to a kind of pressure hole carrier band square hole degree of depth laser measuring device for measuring, belong to paper tape square hole intelligent measure technical field.
Background technology
The development of electronic component and use widely and become one of important symbol of a national electronics industry development level.At present, all kinds of electronic components comprise passive element, electromechanical compo, audio element and composite component, all to complicated, precise treatment and miniaturization development.Therefore the packing of electronic component, the used corresponding carrier band in aspect such as transport, take the protection of electronic component is seemed more and more important.Need the predetermined design of basis on body paper, to be formed for taking in the square hole and the circular hole that is used to carrier band is carried of electronic component in the forming process of carrier band; Whether according to square hole is through hole, can be divided into carrier band cellular type carrier band (square hole adopts method formation through holes such as punching) and press hole carrier band (square hole adopts methods such as pressing the hole to form the shrinkage pool of not punching paper tape).Traditional cellular type carrier band is prone to adhesion, gets stuck, the cost height do not got stuck gradually, need not adhesive tape under the seal, thereby does not exist the pressure hole carrier band of problems such as sizing to replace.
Along with the miniaturization of electrical equipment development, the microminiaturization of electronic component is required increasingly high, electronic element is the main flow form of electronic component in dividing at present, its size is more and more littler.How accurately measure and be used for these electronic component carrying belts and take in the degree of depth of the square hole of electronic component and seem more and more important.For the cellular type carrier band, the degree of depth of square hole is the thickness of carrier band thereby convenient measurement; And for pressing the hole carrier band, because its square hole is a blind hole, the bottom surface in hole is accurate bottom surface; The accuracy requirement in the other side's hole depth, aperture is higher, need be pollution-free when measuring the square hole degree of depth to square hole, and not damaged; Therefore, for a difficult point in the current always precision measurement of the mensuration of the square hole degree of depth of pressing the hole carrier band.Used measurement mechanism is a depth dial gauge at present, needs to guarantee before measuring to be put in carrier band on the platform earlier by each cleaning elements of instrument lightly; Then the measuring head of clock gauge gently be placed on the carrier band surface; Open the clock gauge power supply, after making zero, put into square hole to measuring head lightly again; After pending data was stable, the gained data were the square hole degree of depth.After our actual use, although this method can exist measuring error big, accuracy is low, and the weight of putting into the measuring head of square hole carries out guestimate and measures people's difference and difference according to each, thereby reliable measurement property is lower, and square hole is had certain damage.
At present existing be used for the device that blind hole is measured, in " tool technique " 2010,45 (2), introduced the special built-up jig of a cover that designs based on the raster pattern dial gauge like Liu Dawan etc.; Be installed on the micrometering appearance; Can realize the quick measurement of all kinds of small blind hole depth dimensionses, thereby promote measuring technology, improve detection efficiency; But this built-up jig is mainly used in the blind hole check in the mechanical processing process because of its gauge head is hard; As be used for pressure of the present invention hole carrier band, and bigger to the carrier band damage, thus product quality influenced.Patent CN101819027A discloses a kind of inspection method and device of blind hole depth for another example; Its purpose is in laser drilling process, to obtain accurately, in time the punching degree of depth; Be mainly used in the laser drilling process, obviously be not suitable for for the pressure hole carrier band that forms square hole.Press the hole carrier band because of being used for electronic component, the packing to follow-up electronic component of the square hole degree of depth accurately and reliably be provided, transport, take and have vital role, and the other side's hole depth measure do not see as yet at present accurately, fast, the device of the noninvasive measurement pressure hole square hole degree of depth.
Summary of the invention
