However, keying with mechanical key processing machines often requires manual assistance for key positioning and processing, resulting in a relatively low level of automation.

[0003] To solve this problem, electronic key processing technology has emerged on the market. It reads the key's tooth shape information optically and transmits electronic data to the processing organization.

[0051] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] To achieve the above purpose, the technical solution of the utility model is as follows:

[0053] See also Figure 1-10 As shown, this embodiment provides a key tooth shape data recognition device, comprising:

[0054] Device body 1;

[0055] Optical recognition module 2, used for identifying the key tooth profile data;

[0056] Clamping and positioning mechanism 3, used for clamping and fixing the key;

[0057] The clamping and positioning mechanism 3 and the optical recognition module 2 are both installed in the device body 1 , and a cavity 4 for accommodating a key is also provided in the device body 1 .

[0058] In this embodiment, when using the device, a key is first placed within cavity 4 of device body 1. The key handle is clamped and secured by clamping and positioning mechanism 3. Upon detecting the presence of a key within cavity 4, optical recognition module 2 captures a photo or video to identify the key's tooth profile information. The built-in cavity 4 of device body 1 provides a relatively closed and stable optical environment for optical recognition module 2, preventing external environmental influences during photography, improving image clarity, and ultimately, enhancing the accuracy of key tooth profile recognition.

[0059] Furthermore, the optical recognition module 2 includes a main control PCB (not shown) and a recognition camera 21. The main control PCB and recognition camera 21 are electrically connected and both are fixed to the device body 1. The recognition camera 21 is located at the top of the cavity 4. In this embodiment, the recognition camera 21 serves as the optical recognition element, located at the top of the cavity 4. It can photograph the key from above and transmit the captured photos or videos to the main control PCB. The main control PCB is located on the control host, identifies and compares the key tooth profile data, and transmits it to the processing unit for subsequent key production.

[0060] It should be noted that the main control PCB board uses photos or videos taken by the camera to identify and compare the key tooth shape data, which is a relatively simple computer image processing technology, which is disclosed in the existing patent with application number CN201711091755.7 and will not be described in detail in this embodiment.

[0061] Furthermore, the optical recognition module 2 also includes a filter 22 and a backlight panel 23. The filter 22 and backlight panel 23 are disposed at the bottom of the cavity 4, with the filter 22 disposed between the recognition camera 21 and the backlight panel 23. In this embodiment, the backlight panel 23 serves as the primary light source, emitting white light to illuminate the cavity 4 and provide a basic lighting environment for the cavity 4, facilitating clear key photography by the recognition camera 21 and thereby accurately identifying the key's tooth profile information. The filter 22 is disposed between the recognition camera 21 and the backlight panel 23, filtering the light emitted by the backlight panel 23 and adjusting the lighting environment of the cavity 4 for clearer photography.

[0062] Furthermore, the optical recognition module 2 also includes a three-color LED board 24 for fill light, which is disposed between the recognition camera 21 and the filter 22. As a fill light source, the three-color LED board 24 can provide three different colors of light. The three colors can be used individually or in any combination to fill light into the cavity 4, enabling the recognition camera 21 to capture photos with three different background colors, adapting to keys of different colors and reflectivity, resulting in clearer photos or videos and clearer tooth profile data recognition.

[0063] Further, the three-color LED board 24 includes three supplementary light boards arranged in a stacked manner, and the colored lights provided by the three supplementary light boards are different; the supplementary light board has a "U" - shaped structure and semi - wraps the cavity 4, capable of providing three different colors of light on the periphery of the key to supplement the optical environment of the cavity 4.

[0064] Further, the optical recognition module 2 further includes a lens hood 25. The lens hood 25 is fixed to one side of the device main body 1, and the recognition camera 21 is installed on the lens hood 25.

[0065] Further, the clamping and positioning mechanism 3 includes:

[0066] A rotation driving member 31, fixedly connected to the device main body 1;

[0067] A swinging member 32, movably installed on the device main body 1 and connected to the output end of the rotation driving member 31;

[0068] A clamping component 33, movably installed on the device main body 1 and having a clamping groove 34 with adjustable size, and the clamping groove 34 communicates with the cavity 4;

[0069] A storage port 35 is provided on the device main body 1, and the storage port 35 is arranged opposite to the position of the clamping groove 34;

[0070] The clamping component 33 is movably connected to the swinging member 32, so that the swinging member 32 can trigger the movement of the clamping component 33 to adjust the size of the clamping groove 34 to adapt to keys of different sizes.

[0071] In this embodiment, in the initial state, the clamping groove 34 is opened to the maximum size. When in use, the key is inserted into the clamping groove 34 of the clamping component 33 through the storage port 35 on the device main body 1. The handle of the key will be placed in the clamping groove 34, and the toothed part of the key will extend into the cavity 4 of the device main body 1. After the control host detects that there is a key in the cavity 4, it starts to control the rotation driving member 31 to work. The rotation driving member 31 drives the swinging member 32 to move to one side, and through the swinging member 32, it triggers the movement of the clamping component 33 to adjust the size of the clamping groove 34 to adapt to the size of the key and clamp the key firmly; thus, the clamping and positioning mechanism 3 can clamp and fix keys of different sizes; after the key is clamped and fixed, the optical recognition module 2 works to collect the toothed information of the key. After the collection is completed, the control host controls the rotation driving member 31 to work,带动反向活动,触发夹持组件33活动,释放钥匙,方便钥匙的取出。 (There seems to be an error in this part of the Chinese text. It should be something like "drives it to move in the reverse direction, triggers the movement of the clamping component 33, releases the key, and facilitates the removal of the key.")

[0072] Furthermore, the rotational drive member 31 is a motor, and a synchronous wheel 36 is provided between the motor and the swing member 32. The synchronous wheel 36 is connected to the output end of the motor. The edge of the swing member 32 is provided with meshing teeth 325, and the swing member 32 meshes with the synchronous wheel 36 through the meshing teeth 325. The motor drives the swing member 32 to swing through the synchronous wheel 36, thereby driving the movement of the clamping assembly 33.

[0073] Furthermore, the clamping assembly 33 includes a first slider 331, a second slider 332, and a third slider 333. The first slider 331 and the second slider 332 are horizontally arranged and located on the same straight line. The third slider 333 is cross-arranged with the first slider 331 and the second slider 332, and the clamping groove 34 is arranged between the first slider 331, the second slider 332, and the third slider 333; the device body 1 has a mounting cavity 5, which is connected to the storage port 35. The mounting cavity 5 includes a first sliding groove 51, a second sliding groove 52, and a third sliding groove 53. The first sliding groove 51, the second sliding groove 52, and the third sliding groove 53 intersect at the storage port 35. A supporting protrusion 37 is provided on the side wall of the device body 1. The supporting protrusion 37 is located on the side of the storage port 35, and the supporting protrusion 37 is arranged opposite to the third sliding groove 53. The first slider 331 is slidably set in the first sliding groove 51, and the second slider 332 is slidably set The first and second limit switches 321 and 322 are movably mounted on the support frame 310, so that the second limit switches 321 and 322 can be mounted on the support frame 310 to adjust the size of the clamping groove 340.

[0074] In this embodiment, in the initial state, the clamping groove 34 is at its maximum size. When the key is inserted into the storage port 35, it will be supported by the support protrusion 37. At this time, after the control host detects that there is a key in the cavity 4, the motor drives the swing member 32 to rotate to one side. Under the triggering of the swing member 32, the first slider 331 and the second slider 332 can move toward each other in the horizontal direction, adjust the horizontal size of the clamping groove 34, and facilitate adaptation to keys of different widths; the third slider 333 can move relative to the support protrusion 37 in the vertical direction, adjust the vertical size of the clamping groove 34, and facilitate adaptation to keys of different thicknesses, thereby achieving clamping of keys of different widths and thicknesses; when the key tooth profile data is collected, the motor drives the swing member 32 to rotate in the opposite direction, the first slider 331 and the second slider 332 move in the opposite direction, and the third slider 333 moves back to the support protrusion 37 to release the key.

[0075] Furthermore, the clamping assembly 33 also includes an elastic member 337. The lower end of the elastic member 337 abuts against the third slider 333, and the upper end of the elastic member 337 abuts against the device body 1, so that the third limiting protrusion 336 is continuously in contact with the bottom wall of the third limiting groove 323. In this embodiment, since the first limiting groove 321 and the second limiting groove 322 have the same shape and are symmetrically arranged, when the swinging member 32 moves, it can drive the first slider 331 and the second slider 332 to move closer or farther away synchronously, thereby achieving horizontal positioning of the key. However, since the third slider 333 is used to limit the key vertically, it cannot move synchronously with the first slider 331 and the second slider 332 in terms of structural setting, and can only move asynchronously with the first slider 331 and the second slider 332. Under this premise, it is necessary to ensure that the third slider 333 always clamps the key. When the key is to be fixed on the workbench 323, the third slider 333 can only be pressed downward by the elastic member 337. The elastic member 337 adopts a spring, and the third slider 333 is always pressed against the support protrusion 37 by the elasticity to achieve vertical limitation of the key. At the same time, since the third limiting boss 336 is continuously fitted with the bottom wall of the third limiting groove 323, it can move along the bottom wall of the third limiting groove 323, thereby ensuring that the third slider 333 can slide up and down smoothly under the drive of the swinging member 32, thereby achieving adjustment of the vertical dimensions of the clamping groove 34 to accommodate keys of different thicknesses.

[0076] Furthermore, the first sliding groove 51 , the second sliding groove 52 , and the third sliding groove 53 are all linear grooves, thereby ensuring that the first slider 331 , the second slider 332 , and the third slider 333 move linearly.

[0077] Furthermore, the first limiting groove 321 , the second limiting groove 322 , and the third limiting groove 323 are all irregular arc grooves, so that the first slider 331 , the second slider 332 , and the third slider 332 can be triggered to move linearly by the swing of the swing member 32 .

[0078] Furthermore, the mounting cavity 5 also includes a balance wheel limiting groove 54 , a balance wheel limiting protrusion 55 is provided in the middle of the balance wheel limiting groove 54 , a limiting hole 324 is provided in the middle of the swinging member 32 , and the balance wheel limiting protrusion 55 is passed through the limiting hole 324 .

[0079] Furthermore, the device body 1 includes an identification box 11 and a mounting plate 12. The identification box 11 is hollow to form a cavity 4. The mounting cavity 5 is arranged between the identification box 11 and the mounting plate 12. The first sliding groove 51, the second sliding groove 52, and the third sliding groove 53 are arranged on the inner wall of the mounting plate 12. The balance wheel limiting groove 54 is arranged on the outer wall of the identification box 11. The identification box 11 and the mounting plate 12 are both provided with corresponding storage openings 35.

[0080] Furthermore, the identification box 11 includes a box body 111, a flip cover 112, and a flip drive module 113. The box body 111 and the flip cover 112 enclose a cavity 4. The bottom of the box body 111 is provided with an opening 114 that communicates with the cavity 4. The flip cover 112 is located in the opening 114, and the flip cover 112 is rotatably connected to the bottom of the box body 111 by the flip drive module 113, so that the opening 114 can be opened or closed. In this embodiment, in the normal state, the opening 114 is in a closed state, and normal tooth profile data can be recognized. When the control host detects that there is no key in the cavity 4, the flip drive module 113 drives the flip cover 112 to flip, opening the opening 114, so that the object in the cavity 4 can fall out of the cavity 4, thereby removing the foreign matter.

[0081] Furthermore, the flip drive module 113 includes a flip drive member 1131 and a cover-opening cam 1132. The flip drive member 1131 is fixed to the flip cover 112. One end of the cover-opening cam 1132 is connected to the output end of the flip drive member 1131, and the other end abuts against the bottom of the box body 111. In this embodiment, when the opening 114 needs to be opened, the flip drive member 1131 is activated, driving the cover-opening cam 1132 to rotate. Since one end of the cover-opening cam 1132 abuts against the bottom of the box body 111, the cover-opening cam 1132 provides a reaction force, forcing the flip cover 112 to rotate, thereby opening the opening 114.

[0082] Furthermore, the flip drive module 113 includes a torsion spring 1133 and a rotating shaft 1134. A first hinge protrusion 115 is provided at one end of the flip cover 112, and a second hinge protrusion 116 is provided on the box body 111. The first hinge protrusion 115 and the second hinge protrusion 116 are connected by the rotating shaft 1134, and the torsion spring 1133 is installed on the rotating shaft 1134. In the normal state, the flip cover 112 is placed within the opening 114 under the torsion force of the torsion spring 1133, closing the opening 114. When the flip cover 112 is opened by the strong push of the flip drive member 1131, the torsion spring 1133 is twisted and deformed. When the flip drive member 1131 rotates in the opposite direction, the force of the torsion spring 1133 can restore the flip cover 112 to its original position.

[0083] Furthermore, the flip drive member 1131 is a reduction motor. Under normal circumstances, the torsion force of the torsion spring 1133 on the rotating shaft 1134 keeps the flip cover 112 in a closed state. When the camera detects that there is a foreign object in the identification box 11, the control host sends a command to rotate the reduction motor one or more times. The rotation of the reduction motor drives the cover opening cam 1132 to push open the flip cover 112, allowing the foreign object in the identification box 11 to slide out. When the reduction motor returns to the initial position, the flip cover is reset under the torsion force of the torsion spring 1133.

[0084] Furthermore, the flip cover 112 is provided with a first mounting groove 1121, into which the optical filter 22 and the backlight panel 23 are fixed. Since the optical filter 22 and the backlight panel 23 are located at the bottom of the cavity 4, the flip cover 112 can drive the optical filter 22 and the backlight panel 23 to flip, thereby preventing the optical filter 22 and the backlight panel 23 from blocking the cavity 4 from the bottom, thereby facilitating the smooth escape of foreign matter in the cavity 4.
