Problems solved by technology

However, if the lower thickness detection shaft arranged on the side wall is usually moved in the plane of the side plate of the lower frame due to reasons such as installation accuracy, the predetermined position between the lower thickness detection shaft and the upper thickness detection shaft will change, resulting in The floating amount of the upper thickness detection axis detected by the induction ring is not the thickness of the medium passing through the medium transmission channel, which leads to the technical problem of inaccurate detection of the medium thickness, and makes it impossible for the banknote verification module to correctly identify the medium whose thickness exceeds the threshold. or generate false alarms

Embodiment 1

[0046] This embodiment provides a lower frame 1', on which the bearing 12' for placing the lower thickness detection shaft 13' is installed in the mounting hole on the lower frame 1' through a hot pressing process, so that the bearing 12' and the lower frame The interference fit of the frame 1' restricts the movement of the lower thickness detection shaft 13' in the plane of the side plate 11' itself, which ensures the accuracy of the detection of the thickness of the medium.

[0047] It should be noted that the medium in this application can be made of paper, plastic or similar materials such as paper, banknotes or bills. In all embodiments of the present invention, only banknotes are used as examples for illustration .

Embodiment 2

[0049] Although the banknote detection device in Embodiment 1 can ensure the accuracy of detecting the thickness of banknotes, when the interference fit between the bearing 12' and the lower frame 1' is realized through the hot pressing process, there will be the following two problems:

[0050] First, the bearing 12' is a wear-and-tear part. When the bearing 12' has been used for too long and the bearing 12' needs to be replaced, the side plate 11' of the lower frame 1' needs to be replaced together with the bearing 12', resulting in a waste of resources. Waste, increase the use cost of banknote inspection device;

[0051]Secondly, the bearing 12' is installed through the hot pressing process, which has high requirements on the machining accuracy of the bearing 12' and the mounting hole, and also has strict requirements on the hot pressing temperature, which makes the installation of the bearing 12' complicated and time-consuming. Processing costs are high.

[0052] So, if ...

Abstract

The invention relates to a lower rack, a medium inspection device and a financial self-service terminal. The lower rack comprises two side plates, bearings, a lower thickness detection shaft and pressing plates, wherein the two side plates are arranged opposite to each other; mounting holes are formed in the side plates; peripheral surfaces of the bearings are accommodated inside the mounting holes and are propped against the inner walls of the mounting holes; two ends of the lower thickness detection shaft are respectively arranged in the bearings in a penetration manner and are used for detecting the thickness of a medium; the pressing plates are propped against the peripheral surfaces of the bearings and are fixed with the side plates through fixing parts; and the peripheral surfaces of the bearings are clamped and fixed by the pressing plates and the mounting holes together. By adopting the lower rack, on the premise that the bearings are conveniently replaced, the lower thickness detection shaft is prevented from moving in a plane of the side plates, and thus the precision of the medium inspection device in inspecting the thickness of the medium is improved.

Description

technical field [0001] The invention relates to measurement and control technology, in particular to a lower frame, a medium inspection device and a financial self-service terminal. Background technique [0002] With the development of society, financial self-service terminals can be seen everywhere in daily life, which not only reduces the work intensity of bank staff, improves the work efficiency of bank staff, but also saves customers time for various financial services. Since the financial self-service terminal involves the business of accessing media, it is equipped with a banknote verification module to verify the authenticity of the media deposited or withdrawn, effectively safeguarding the interests of the bank and customers, and greatly avoiding disputes between the bank and customers . [0003] At present, a medium inspection device is installed inside the banknote inspection module for inspecting the thickness of the medium. The medium inspection device includes...
