Description

Technical Field

[0001] The utility model belongs to the technical field of measuring equipment, and in particular relates to a device for measuring the number of voucher accessories. Background Art

[0002] Existing devices for measuring the number of voucher attachments have some significant shortcomings in terms of errors. First, when such devices detect the number of voucher attachments, they are often affected by the diversity of attachment sizes, shapes and materials, resulting in errors. Specifically, some devices rely on optical or mechanical sensing principles. When the thickness, transparency or reflectivity of the attachments are different, it is easy to cause the sensor to misjudge and count errors. This problem mainly stems from the fact that all possible attachment characteristics are not fully considered when designing the equipment, or the sensitivity and resolution of the sensor are not high enough. Secondly, stacking or adhesion of accessories is also a common problem. When multiple accessories are stacked tightly or stuck together due to static electricity and other reasons, it is difficult for the device to accurately distinguish them, resulting in counting errors. In addition, changes in the operating environment, such as fluctuations in light, temperature and humidity, will also affect the measurement results, further exacerbating the errors.

[0003] In order to deal with these problems, conventional methods include: improving the sensitivity and resolution of sensors, using more advanced optical and mechanical detection technologies to enhance the ability to identify accessories with different characteristics; introducing intelligent algorithms to automatically correct and filter errors through multiple measurements and data comparisons; maintaining stable environmental conditions during equipment operation to reduce interference from external factors. However, these methods also have obvious disadvantages. Improving sensor performance and using advanced technology usually significantly increase the manufacturing cost of equipment, making the equipment expensive and increasing the economic burden on users when purchasing and maintaining it; although the introduction of intelligent algorithms can improve accuracy, it may require higher computing resources and more complex software support, increasing the complexity of the system and the potential risk of failure; maintaining a stable operating environment has high requirements for the place of use, which limits the scope of application of the equipment, especially in places where environmental conditions are difficult to control. Therefore, we hope to design a voucher attachment quantity measurement device with a new structure to solve this problem. Utility Model Content

[0012] As a preferred embodiment, the lower pressure part includes a top plate and a laser ranging sensor. A laser ranging sensor is installed on the left and right ends of the top plate respectively. The height of the lower end of the laser ranging sensor is flush with the height of the lower surface of the top plate.

[0029] On the front and rear sides of the outer shell 210, sealed glass doors 230 are respectively sealed and hinged. On the left side of the upper end of the outer shell 210, a driving member 220 is installed. In the middle of the bottom of the outer shell 210, a measuring table 240 is fixed.

On the left side, right side, front side and rear side of the upper surface of the measuring table 240, two positioning members 270 are respectively movably installed.

[0031] Please refer to Figures 1 to 5 , on the left end and the right end of the outer shell 210, a transparent observation window is respectively fixed. Each sealed glass door 230 is composed of two single - leaf glass doors that can freely open and close.

[0032] The measuring table 240 includes guide posts 241, a measuring base plate 242, a bottom plate 243 and sliding grooves 244. On the front side, rear side of the left end and the front side, rear side of the right end of the upper surface of the bottom plate 243, a guide post 241 is respectively fixed;

[0033] On the front side, rear side, left side and right side of the upper surface of the bottom plate 243, two parallel - arranged sliding grooves 244 are respectively formed by downward depressions. The outer end of each sliding groove 244 penetrates through the edge of the bottom plate 243. The setting of the measuring table 240 facilitates the placement of voucher attachments.

[0034] In the middle of the left end and the middle of the right end of the bottom plate 243, a measuring base plate 242 is respectively arranged. The height of the upper surface of the measuring base plate 242 is flush with the height of the upper surface of the bottom plate 243.

[0035] The upper pressing member 250 includes a top plate 251 and a laser distance sensor 252. On the left end and the right end of the top plate 251, a laser distance sensor 252 is respectively installed.

[0038] As the first embodiment of the utility model, in actual use, a voucher attachment of a certain thickness is placed on the upper side of the bottom plate 243 of the measuring table 240, and then the multiple positioning members 270 on the bottom plate 243 are pushed to limit the voucher attachment to avoid collapse or skewness of the voucher attachment when the pressing member 250 is pressed down for measurement, so as to ensure a successful measurement. After the voucher attachment is positioned by the multiple positioning members 270, the driving member 220 is started (the driving member 220 is composed of a servo motor and a screw rod, and the screw rod is used to drive the top plate 251 to move on the four guide pillars 241 through the screw nut installed on the top plate 251, see the attached manual for details Figure 2 ), driving the top plate 251 on the pressing member 250 to move downward, under the action of the four guide pillars 241, the top plate 251 is stably pressed down, and the upper ends of the blocking rods 272 on the multiple positioning members 270 penetrate the top plate 251 through the multiple giving way grooves 253 on the top plate 251 to avoid movement interference. In the process of the top plate 251 being pressed down, it will gradually contact the uppermost side of the voucher attachment and synchronously contact the pressure sensor 263 on the upper end of the pressure measuring member 260. After the pressure sensor 263 on the upper side of the pressure measuring member 260 is pressurized, it can continue to move downward under the action of the spring telescopic rod 262 (the spring telescopic rod 262 includes a telescopic rod, a spring and a telescopic cylinder, and the lower end of the telescopic rod is installed inside the upper end of the telescopic cylinder through the spring telescopic movement) until the required measurement pressure value is met. At this time, the distance measured by the laser ranging sensor 252 from the lower end to the upper surface of the measuring substrate 242 is the thickness value of the voucher attachment, which can improve the measurement accuracy and can flexibly cope with the real thickness measurement of papers with different degrees of wrinkles.

[0039] See also Figure 2 , Figure 5 The pressure measuring component 260 includes a mounting seat 261, a spring telescopic rod 262 and a pressure sensor 263.

A spring telescopic rod 262 is fixed in the middle of the upper surface of the mounting seat 261, and a pressure sensor 263 is fixed at the upper end of the spring telescopic rod 262. The setting of the pressure measuring component 260 helps to assist in controlling the downward force of the pressing component 250 to avoid excessive downward pressure that reduces the measurement accuracy.

[0040] The positioning member 270 includes a slider 271 and a stop rod 272 . The lower end of the slider 271 is slidably mounted in the slide groove 244 on the bottom plate 243 .
