Mechanism for controlling semi-automatic book and periodical scanner to complete manuscript pressing glass automatic lifting and automatic scanning process by adopting grating sensor

Abstract

The utility model discloses a mechanism for triggering and controlling a semi-automatic book and periodical scanner to complete automatic lifting and automatic scanning processes of a pressing frame by adopting grating sensors, which consists of a pair of grating sensors, a stepping motor, a clutch component, a position sensor and a manuscript glass pressing component, when the hands finish page turning and leave the grating sensor arranged in front of the operation platform, the manuscript pressing glass part can automatically press downwards, and after the manuscript pressing glass part is pressed downwards to a certain position to finish photographing or scanning, the manuscript pressing glass part ascends to automatically return to the initial position, so that the automatic lifting and automatic scanning process of the manuscript pressing glass part of the semi-automatic book and periodical scanner is finished; in the automatic lifting operation process of the glass pressing frame, if the grating sensor is triggered by hands, the glass pressing frame can automatically stop, and safety accidents such as hand clamping are prevented.

Description

TECHNICAL FIELD

[0001] The utility model is applied to the book scanner with the glass, and aims at solving the automatic lifting of the glass and the automation of scanning, and simultaneously solving the safety problem of preventing the hand from being pressed. BACKGROUND

[0002] At present, the semi-automation of the traditional book scanner with the glass includes the automatic pressing and lifting of the glass and the automatic triggering of scanning, and the triggering of the semi-automatic function is mainly realized by the key triggering, which is not automatic and not advanced enough. SUMMARY

[0003] In view of the fact that the traditional semi-automatic book scanner with the glass cannot automatically trigger the automatic pressing and lifting of the glass, the utility model designs a mechanism composed of a pair of grating sensors 5, a stepping motor 6, a clutch component 7, a position sensor 8 and a glass component 3. BRIEF DESCRIPTION OF DRAWINGS

Figure 1 In the figure, 1 is a scanning head, 2 is a column component, 3 is a glass component, 4 is an operation platform base, 5 is a grating sensor, 6 is a stepping motor, 7 is a clutch component, and 8 is a position sensor. Figure 2 It is a schematic diagram of a scanner with an operation platform and a glass. Figure 2 In the figure, 9 is a V-shaped supporting plate component, and 10 is a book paper file. DETAILED DESCRIPTION

[0005] The utility model mainly applies to the book scanner with the glass of pressing manuscript, and the scanner generally mainly contains the scanning head, the column component, the glass of pressing manuscript component, the operation platform base, the grating sensor, the stepping motor, the clutch, the supporting plate component etc., the clutch component 7, the stepping motor 6, V-shaped supporting plate component 9, column component 2 are installed on the operation platform base 4, the scanning head 1, the glass of pressing manuscript component 3, position sensor 8 are installed on the column component 2, the grating sensor 5 is installed on the operation platform base 4 top, the position is in the glass of pressing manuscript component 3 front proper position, and each is in left and right, and the stepping motor 6 is driven clutch 7 with stepping belt, and the clutch 7 is linked with the glass of pressing manuscript component with belt, when the operator opens the paper file 9 after using hand, the grating sensor 5 is triggered when the hand retracts and leaves the grating sensor 5 opposite position, then the stepping motor 6 rotates, and the clutch 7 is attracted, and the glass of pressing manuscript component 3 is driven to do the lifting movement, thereby the automation function of down pressure, scanning, reset is completed, during the lifting movement of the glass of pressing manuscript component 3, if there is object (including human hand) from the front into the grating sensor 5 opposite position, the lifting movement of the glass of pressing manuscript component 3 will be automatically stopped.
