Detailed Description
For further explanation of the principles and construction of the present invention, reference will now be made in detail to the preferred embodiments of the present invention, which are illustrated in the accompanying drawings.
Referring to fig. 1 and 2, the encryption keyboard of the present invention includes 16 keys 2, which are respectively disposed on a metal panel 1 and 4 × 4, and each key 2 is disposed in a corresponding opening of the metal panel 1. The keypad also includes two bumps 3 protruding above the upper surface 11 of the metal panel 1.
Preferably, the bumps 3 are stamped and formed. The salient points 3 at the two positions can be realized by adopting the same die in sequence or can be realized by adopting two dies simultaneously. The positions of the two bumps 3 on the metal panel 1 are random. Preferably, the metal panel 1 is made of stainless steel and has a thickness capable of meeting certain strength requirements, such as: the thickness was 3 mm.
The upper surface 21 of the key 2 may be flush with the upper surface 11 of the metal panel 1, even slightly lower than the upper surface 11 of the metal panel 1, or may protrude from the upper surface 11 of the metal panel 1 by a first set height, so that an operator can notice the existence of the adhesive film during the use process. Preferably, the first set height is 1.0-1.5 millimeters.
The tops 31 of the two bumps 3 protrude from the upper surface 11 of the metal panel 1 by a second predetermined height. The second set height may be equivalent to the first height, or may be greater or less than the first set height. Also, the heights of the tops 31 of the two bumps 3 protruding from the upper surface 11 of the metal panel 1 may not be equal. But should satisfy the requirement that the raised point 3 is raised above the upper surface 21 of the key 2 when the key 2 is depressed. The arrangement of the salient points 3 can greatly increase the difficulty of stealing the password by the film sticking of the illegal person, thereby playing a role in effectively preventing the password from being stolen by the film sticking.
The base of the two bumps 3 is circular, preferably 3 mm in diameter. The bottom diameters of the two bumps 3 may not be equal.
It should be noted that, although two bumps 3 are taken as an example above, depending on different situations such as the effect to be achieved actually and the setting of the manufacturing cost, it is also possible to provide only one bump 3, three bumps 3, four bumps 3, or even more bumps 3, and obviously, in a certain range, the larger the number of bumps 3, the better the crime prevention effect.
Referring to fig. 3, the method for manufacturing the above-mentioned encryption keyboard of the present invention includes the manufacturing of a metal panel, and the manufacturing process of the metal panel includes the following steps:
s110: randomly acquiring the set positions of the two salient points according to the shape and the size of the metal panel;
s120: the stamping die moves to a first set position relative to the metal panel;
s130: making the stamping die act relative to the metal panel to form a first salient point on the metal panel;
s140: the stamping die moves to a second set position relative to the metal panel;
s150: the stamping die is made to act relative to the metal panel, and a second salient point is formed on the metal panel.
The term "the stamping die is relative to the metal panel" may refer to the metal panel being stationary and the stamping die being movable, or the metal panel being movable and the stamping die being stationary. The stamping die comprises a male die and a female die which are matched with each other, and in the case that the salient points 3 are approximately spherical, the male die can be designed to be provided with spherical convex parts, the female die can be designed to be provided with spherical concave parts, the female die is arranged on the side facing the upper surface 11 of the metal panel 1, and the male die is arranged on the side away from the upper surface 11 of the metal panel 1.
In the case of manufacturing several metal panels, or in the case of mass production of metal panels, the manufacturing process of each metal panel may be performed sequentially, and the bump coordinate positions on each metal panel are different. Obviously, the random acquisition of the coordinate position of the salient point can be realized by adopting a control system connected with an action mechanism of the stamping equipment and corresponding software running on the control system, and a specific strategy can be that an initial point is randomly selected within the constraint range of the shape and the size, and then the position of the next point is calculated according to a certain offset algorithm. The acquisition of the bump positions of different metal panels is performed continuously. The two bumps 3 on the same metal panel may be formed by moving the same press mold between two different set positions in series, or by moving the two press molds to a set position in parallel, respectively.
It should be noted that, although two bumps 3 are taken as an example, the same can be true for the stamping of one bump 3, or three bumps 3, four bumps 3, or even more bumps 3.
Compared with the prior art, the encryption keyboard and the manufacturing method thereof have the advantages that the irregularly positioned convex points 3 are punched on the metal panel 1, comparability and referential property do not exist, an operator can easily find the existence of the adhesive film, so that important information such as passwords stolen by the adhesive film can be effectively prevented, and the safety of inputting the passwords is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, so that the equivalent structural changes made by using the contents of the present specification and the attached drawings are included in the scope of the present invention.
