Detailed Description

Embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention to those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it is to be understood that the invention is not to be limited to the specific embodiments described. Rather, any combination of the following features and elements, whether related to different embodiments or not, is contemplated to implement the present invention. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly recited in a claim.

Referring now to fig. 1-3, wherein fig. 1 shows a front view of an imprint testing apparatus according to an embodiment of the present invention; fig. 2 shows a partial front view of an upper half of an imprint testing apparatus according to an embodiment of the present invention; fig. 3 shows a partial perspective view of an upper half of an imprint testing apparatus according to an embodiment of the present invention.

As shown in fig. 1 to 3, the imprint testing apparatus 100 includes:

a work table 1;

the vertical bracket 2 is positioned on one side of the workbench 1 and is fixed with the workbench 1;

a mobile platform 3, which is positioned on the workbench 1, is configured to be capable of horizontally moving transversely and longitudinally on the plane of the workbench 1, and is capable of placing and holding a certificate 4 to be tested thereon;

a cam 5 located on the vertical support 2 above the moving platform 3 and configured to be able to rotate under a first motor drive (not shown);

a follower 6 engaging with an outer contour of the cam 5;

the connecting rod 7 is vertically placed in a slide way 9 formed on the vertical support 2, the first end of the connecting rod is connected with the driven piece 6, and the second end of the connecting rod is fixedly connected with the simulation stamp 8;

and the simulation stamp 8 has a first weight, is driven by the connecting rod 7 to continuously move upwards along with the continuous upward movement of the driven part 6 until reaching the highest point in the process that the cam 5 rotates from the initial angle position to the initial angle position for one circle, and then falls downwards as a free falling body under the action of the first weight to fall on the certificate to be tested 4 on the moving platform 3.

The working platform 1 is any support capable of supporting the moving platform 3 and the vertical support 2.

The vertical support 2 may be fixed to the table 1 in any manner, or may be integral with the table 1. The vertical support 2 is located at one side of the table 1 and may have an extension above the moving platform 3.

The moving platform 3 can be arranged on the working platform 1 through a motion mechanism 9. The moving mechanism 9 can make the moving platform 3 move longitudinally and transversely on the horizontal plane. For example, the movement mechanism 9 may comprise a transverse screw-nut mechanism and a longitudinal screw-nut mechanism. The nut of the transverse lead screw nut mechanism can be fixedly connected with the moving platform 3, and the lead screw of the transverse lead screw nut mechanism can be driven to rotate by the second motor, so that when the second motor rotates, the nut can be driven to move by the rotation of the lead screw, and the moving platform 3 is driven to transversely move. The nut of the longitudinal screw-nut mechanism can be fixedly connected with the transverse screw-nut mechanism, and the screw of the longitudinal screw-nut mechanism can be driven to rotate by the third motor, so that when the third motor rotates, the nut can be driven to move by the rotation of the screw, and the transverse screw-nut mechanism and the moving platform 3 are further driven to move longitudinally.

The mobile platform 3 may have a flat and rigid surface for placing thereon documents to be tested, such as travel passports and the like. The mobile platform 3 may also have a mechanism for fixing the document 4 to be tested, such as a movable buckle.

The shaft of the cam 5 may be arranged on the vertical support 2 (for example by means of a bearing) and may be driven in rotation by the first motor, so as to bring the cam 5 itself in rotation with its axis of rotation. For example, the shaft of the cam 5 may be connected to the shaft of the first motor through a gear transmission mechanism, or may be coaxial with the shaft of the first motor so as to be rotated by the driving of the first motor.

The follower 6 engages with the outer contour of the cam 5, so that the follower 6 moves up and down in the vertical direction when the cam 5 rotates. The follower 6 may be any suitable cam follower such as a roller follower, a flat bottom follower, a point follower, etc. In some embodiments, the follower 6 is a roller follower, i.e. a roller that can roll on the outer profile of the cam 5.

The connecting rod 7 is vertically placed in a slide 9 formed on the vertical bracket 2, and the slide 9 may be an opening of a horizontal plate 10 on the vertical bracket 2, for example, so as to support the connecting rod 7 to prevent it from swinging in the horizontal direction.

A first end of the connecting rod 7 may be connected with the follower 6. For example, in the embodiment where the follower 6 is a roller, the roller may rotate about a fixed axis, and the first end of the link 7 is fixedly connected to the fixed axis.

The second end of the connecting rod 7 can be connected with a simulation stamp 8. The connection may be, for example, a detachable connection, such as a threaded connection, a bayonet connection, or the like.

The simulated stamp 8 may have a greater weight so as to be able to exert a greater impact force on the document 4 to be tested, depending on its own weight. For example, the module stamp 8 may be a stainless steel metal cylinder. In particular, when the cam 5 is in an initial angular position, the follower 6 is at the smallest radial on the outer profile of the cam 5, and is therefore at the lowest position; along with the rotation of the cam 5, the follower 6 continuously moves upwards along the outer contour of the cam, and drives the connecting rod 7 and the simulation stamp 8 to continuously move upwards until reaching a highest point; then, with the continuous rotation of the cam 5, because the outer contour of the cam 5 contacted by the follower 6 is suddenly reduced to be close to the minimum radial diameter, the follower 6, the connecting rod 7 and the simulation stamp 8 are used as free falling bodies under the action of the weight of the simulation stamp, and rapidly fall down to fall on the certificate 4 to be tested, so that a large impact force is generated on the certificate 4 to be tested, and the impact force of an actual stamp on the certificate is simulated.

In some embodiments, the profile of the cam 5 is: taking the shortest radial direction of the cam 5 as a reference, the radial value is increased smoothly along with the increasing of the radial angle; when the radial value reaches the maximum value, the radial value suddenly drops to approach the shortest radial as the radial angle further increases.

Referring now to fig. 4, a front view of a cam 5 according to an embodiment of the present invention is shown. As shown in fig. 4, the cam 5 has a shortest radial dimension of 15mm and a maximum radial dimension of 120 mm. Along a shortest radial line l₀The radial angle θ as a reference gradually increases, and the radial value smoothly gradually increases to 15 mm. When the radial angle reaches about 240 degrees, the radial value reaches a maximum of 120 mm. Thereafter, as the radial angle θ is further increased, the radial value initially remains constant, then abruptly decreases to approximately 15mm, which is the minimum radial value, and remains constant until it returns to the reference radial line l₀. Of course, the shape and dimensions of the various parts of the cam shown in fig. 4 represent only one exemplary embodiment of the cam 5 of the present invention, and in other embodiments, the cam may have other shapes and dimensions.

Referring now to fig. 5, a perspective view of a simulated stamp 8 is shown according to an embodiment of the present invention. As shown in fig. 5, the bottom surface of the analog stamp 9 is a series of grooves in the shape of concentric circles, which may be etched, for example. The size of the bottom surface of the simulation stamp 9 may be the common size of an actual stamp, the material thereof may be, for example, stainless steel, and the surface may be covered with a rubber pad.

In some embodiments, the imprint testing apparatus 100 may further include a controller 11 configured to control the rotation of the cam 5 by the first motor and to control the horizontal lateral and longitudinal movement of the moving platform 3.

The controller 11 may be in communication with the first, second, and third motors so that the rotation of the cam and the horizontal lateral and longitudinal movement of the moving platform 3 may be controlled by controlling the operation of the first, second, and third motors. The controller 11 may be a computing device such as a computer, microcontroller, microprocessor, etc., and the first motor, the second motor, and the third motor may include respective motor controllers, and the controller may send respective instructions to the motor controllers to control the operation of the motors.

In some embodiments, the imprint testing apparatus 100 may further include a human interface 12 communicatively coupled to the controller 11, the human interface 12 configured to allow a user to set operational parameters of the imprint testing apparatus 100. The human-computer interaction interface 12 may include, for example, output devices such as a display, and input devices such as a mouse, a keyboard, and keys; or a touch screen integrated with input and output functions. In some embodiments, the human-machine interface 12 can also be considered as a part of the controller 11. Through the human-computer interface 12, the user can set the operation parameters of the imprint testing apparatus 100, such as the rotation speed of the cam 5, the horizontal lateral and longitudinal movement speeds of the moving platform 3, the falling height of the dummy stamp 8, the apparatus operation time, and the like. The human-computer interface 12 may transmit the user's settings to the controller 12, and the controller 12 may control the motor controllers according to the user's settings to control the operation of the motors.

In some embodiments, the controller 11 is further configured to control the rotation of the cam 5, and the horizontal lateral and longitudinal movement of the moving platform 3, such that the simulated stamps 8 sequentially land on the entire surface of the document 4 to be tested at even intervals. For example, the initial falling position of the simulation stamp 8 may correspond to the upper left corner of the certificate 4 to be tested, and then the moving platform 3 moves along the transverse direction, so that the subsequent falling positions of the simulation stamp 8 are sequentially rightward at regular intervals until the subsequent falling positions are located at the upper right corner of the certificate to be tested; then, the moving platform 3 transversely returns to the initial position and longitudinally moves for an interval, so that the falling position of the simulation stamp 8 is sequentially positioned at each position from left to right of the second row of the certificate to be tested, and so on, until the simulation stamp 8 sequentially falls at each position on the whole surface of the certificate to be tested 4.

In some embodiments, the imprint testing apparatus 100 further includes: an on-off button 13 for turning on and off the imprint testing apparatus by a user; and an emergency stop button 14 for emergency stopping of the operation of the imprint testing apparatus by a user. The on/off button 13 may be electrically connected to the controller 11, allowing a user to start and stop the controller 11 by pressing the on/off button 13. The emergency stop button 14 may be electrically connected to the controller 11 or directly to each motor controller, thereby allowing a user to emergency stop the operation of each motor to cope with an emergency situation and to keep personnel or equipment safe.

In other embodiments of the invention, the apparatus may have more, fewer, or different modules, and the connections, inclusions, and functional relationships between the modules may be different than described and illustrated.
