Embodiment 1

[0029] Such as image 3 As shown, when working, the measurement steps of thin sheet thickness are as follows:

[0030] First install a standard block with a standard height on the fixed platform, and its height value is X0;

[0031] Slide the slide bar 21 of the measuring mechanism so that the light-emitting window 222 of the contact probe 22 is vertically aligned with the standard block;

[0032] The light-emitting window 222 of the touch probe 22 emits a light beam, and the light beam reaches the surface of the standard block for reflection. The light-receiving window 223 is displaced from the theoretical reflection point Z0, and reflected to the Z1 position. The control system records the value;

[0033] Remove the standard block, place the plate to be tested, and allow the light-emitting window 222 of the touch probe 22 to be vertically aligned with the surface of the plate;

[0034] The light-emitting window 222 of the touch probe 22 emits a light beam, which reaches th...

Embodiment 2

[0039] Such as Figure 4 As shown, when working, the measurement steps of thin sheet thickness are as follows:

[0040] First install a standard block with a standard height on the fixed platform, and its height value is X0; slide the slide bar of the measuring mechanism, so that the probe of the touch probe is vertically aligned with the standard block; the touch probe 22 in the vertical direction Begin to move downward along the initial position Z0 of the slide bar 21 until the probe touches the surface of the standard block. At this time, the contact probe drops to the Z1 position, and this time is set as the measurement zero point, corresponding to the standard block 24 having a thickness of X0, the control system of the displacement sensor records this value;

[0041] Move the touch probe from Z1 back to the Z0 position, remove the standard block, place the thin plate to be tested, and let the touch probe drive the probe downward from the Z0 position again until the prob...

Abstract

The invention provides a contact type thin plate thickness manual measurer. The contact type thin plate thickness manual measurer comprises a base measuring platform, a measuring mechanism and a fixed workbench, wherein the base measuring platform comprises a beam, a support and a platform plane and is built through adoption of a fixed gantry structure; the beam is connected with the support; the support is fixed on the platform plane; the measuring mechanism comprises a slide bar and a contact type measuring head; the beam is sleeved with a slide bar on which a track is carved and the contact type measuring head capable of doing vertical up-and-down movement is mounted; the fixed workbench is detachably arranged below the contact type measuring head and on the platform plane; and the fixed workbench comprises a mounting pedestal, a right-angle locating rule, an absorption mesh pore plate and an absorption airflow trough plate. The contact type thin plate thickness manual measurer, disclosed by the invention, has the advantages of removing a complex shafting structure as a manual measuring way is adopted for measuring, simplifying complex degree of an equipment system to the maximum limit, lowering equipment hardware cost and extremely adapting to practical demands of industries to the thin plate thickness measuring equipment.

Description

technical field [0001] The invention relates to the technical field of application of precision thin plates, in particular to a contact-type manual measuring instrument for the thickness of thin plates. Background technique [0002] In industries such as Surface Mount Technology (SMT for short) of electronic circuits and the application of precision thin sheets, the measurement accuracy of the thickness of incoming thin sheets is usually a key quality control link to ensure the processing quality of subsequent processing procedures. The thickness of the board is generally below 0.3mm, and the format size is usually above 400mm×400mm, and all of them have the characteristics of thin material, high precision, large format and high flexibility. [0003] With the development of society and economy, the market puts forward higher and higher requirements for the quality, processing efficiency and cost of end products such as chips. The format size of thin plates is still gradually...
