Description

Technical Field

[0001] This invention relates to the field of scanning technology, and in particular to an automatic key scanner. Background Technology

[0002] Traditional key duplication relies on manual comparison and filing, requiring users to travel to fixed stalls with their original keys, a time-consuming process. To alleviate the inconvenience of "wanting to travel a long way when the key is lost," automatic scanning and key duplication devices have emerged to replace the traditional method of manual filing. Current key scanners take photos of the key from different angles and stitch them together to form a key image. However, during the photo taking process, the key's material or surface coating can easily reflect light, leading to flaws in the stitched image and rendering the key unusable.

[0003] Therefore, there is a need to provide an automatic key scanner to solve the above-mentioned technical problems. Summary of the Invention

[0037] The present invention provides an automatic key scanner, comprising a housing 11, a clamping device 12 mounted on the housing 11 for clamping or releasing a key, a scanning device 13 mounted on the clamping device 12 for scanning a key, and a control plate 134 mounted on the scanning device 13. A first through hole 111 for inserting a key is provided on one side of the housing 11. The clamping device 12 includes a fixing plate 121 mounted inside the housing 11 and having a notch, a clamping plate 122 located within the notch and movable along the length of the notch, and a first driving assembly 123 mounted on the top of the fixing plate 121 for driving the clamping plate 122 to move along the length of the notch. The scanning device 13 includes components rotatable on the fixing plate 121. The system includes an image chamber 131, a second drive assembly located on one side of the image chamber 131 for driving the image chamber 131 to rotate, and a scanning camera 135 mounted on the image chamber 131 and communicating with the interior of the image chamber 131. The clamping plate 122 is positioned to mate with the notch, which overlaps with the first through hole 111. The image chamber 131 rotates around the first through hole 111. The housing 11 is used to mount the clamping device 12. The scanning device 13 is mounted on the clamping device 12. The control board 134 is mounted on the scanning device 13. The control board 134 is used to control the clamping device 12 to clamp the key and to control the scanning rotation to scan the key. The first drive assembly 123 is used to drive the clamping plate 122 away from or to mate with the top wall of the notch. The image chamber 131 is used to hold or release the key. It rotates to drive the scanning camera 135 to rotate around the key for scanning. When the scanner scans the key, firstly, the front part of the key is inserted into the image chamber 131, and the tail part is placed between the notch and the clamping plate 122. The key portion of the key enters the image chamber 131 from the housing 11. The control board 134 activates the first drive assembly 123, which drives the clamping plate 122 to move towards the top wall of the notch, causing the clamping plate 122 to fit against the key. The key is mutually restrained by the clamping plate 122 and the top wall of the notch to prevent it from loosening or moving. After the key is secured, the control board 134 controls the... The scanning camera 135 and the second drive component are activated. When the scanning camera 135 is activated, it scans the key in the image compartment 131. The second drive component is activated to drive the image compartment 131 to rotate. The scanning camera 135 is mounted on the image compartment 131. When the image compartment 131 rotates, the scanning camera 135 follows the rotation of the image compartment 131, thereby performing a full-range scan of the key in the image compartment 131. The data scanned by the scanning camera 135 is processed by the control board 134 to generate a 3D model. Through the above operations, the scanning camera 135 can completely scan all the details of the key to reduce the flaws caused by image stitching, thereby effectively improving the accuracy of key scanning and making the subsequent key matching more accurate.

[0038] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 4 This is a top view of the clamping device of the scanner for the automatic scanning key of the present invention. Figure 5 for Figure 4 A sectional view taken along the cutting line AA. Figure 6 for Figure 5 A magnified view of part A in the middle. Figure 7 This is a perspective view of the clamping plate of the scanner for the automatic scanning key of the present invention. The first driving assembly 123 includes a fixing seat 1232 symmetrically mounted on the top of the fixing plate 121, a first motor 1231 mounted on one side of the fixing seat 1232, a lead screw 1234 with both ends respectively mounted on the symmetrical fixing seats 1232, and a pressing block 1235 mounted on the lead screw 1234. The first motor 1231 is drivenly connected to the lead screw 1234. The clamping plate 122 is provided with a through groove 1223 extending along the width direction of the fixing plate 121 and a limiting block 1221 located on the top wall of the through groove 1223. The lead screw 1234 and the pressing block 1235 are both located in the through groove 1223. The first motor 1231 drives the lead screw 1234 to rotate, and the pressing block 1235 presses the limiting block 1221. To allow the clamping plate 122 to move closer to or further away from the top wall of the notch, symmetrical fixing seats 1232 are used to mount the first motor 1231 and the lead screw 1234. The pressing block 1235 is connected to the lead screw 1234. Both the lead screw 1234 and the pressing block 1235 are located in the through groove 1223 of the clamping plate 122. The pressing block 1235 is used to press the limiting block 1221. When the first drive assembly 123 drives the clamping plate 122, the first motor 1231 drives the lead screw 1234 to rotate. When the lead screw 1234 rotates, it drives the pressing block 1235 to move in the through groove 1223, so that the pressing block 1235 presses the limiting block 1221, thereby moving the clamping plate 122 toward or away from the top wall of the notch, so that the clamping plate 122 clamps or releases the key.

[0039] The pressing block 1235 is provided with a first inclined surface 1236, and the limiting block 1221 is provided with a second inclined surface 1222 that matches the first inclined surface 1236. The first inclined surface 1236 of the pressing block 1235 and the second inclined surface 1222 of the limiting block 1221 are in contact. When the top of the first inclined surface 1236 of the pressing block 1235 moves towards the top of the second inclined surface 1222, the pressing block 1235 drives the clamping plate 122 to move away from the top wall of the notch, which is used to release the clamped key or to facilitate the key to be placed between the top wall of the notch or the clamping plate 122. When the top of the first inclined surface 1236 of the pressing block 1235 moves towards the bottom of the second inclined surface 1222, the pressing block 1235 is used to drive the clamping plate 122 towards the top wall of the notch, so as to clamp the key.

[0040] The first drive assembly 123 is also provided with symmetrical springs 1233; the bottom wall of the through groove 1223 is also provided with symmetrical circular pillars 1224, and the fixing seat 1232 is also provided with a first lug. A slot is also provided at the position opposite to the first lug and the circular pillar 1224. One end of the spring 1233 is sleeved on the circular pillar 1224 to prevent the spring 1233 from separating from the clamping plate 122, and the other end of the spring 1233 is located in the slot to prevent the spring 1233 from separating from the fixing plate 122. When seat 1232 separates, spring 1233 is a compression spring. When the first inclined surface 1236 of the pressing block 1235 moves downward to the second inclined surface 1222, clamping plate 122 moves towards the top wall of the notch. When clamping plate 122 is in contact with the key, if clamping plate 122 continues to move, spring 1233 plays a buffering role. Spring 1233 deforms after being stressed, preventing excessive downward pressure from clamping plate 122 from damaging the key, thereby protecting the user's key.

[0041] Please refer to Figure 9 , Figure 9 The scanning device 13 of the present invention is provided with a flange mounting base 133 for the scanner of the automatic scanning key. The flange mounting base 133 is fixed on the fixing plate 121. A ring gear 1311 is provided on the periphery of the image chamber 131 near the fixing plate 121. The second drive assembly includes a second motor 132 fixed on the flange mounting base 133 and a first gear 1321 driven by the second motor 132. The first gear 1321 meshes with the ring gear 1311. The flange mounting base 133 is used to fix the image chamber 131 and the second drive assembly on the fixing plate 121. The second motor 132 drives the ring gear 1311 to rotate through the first gear 1321, thereby realizing that the second motor 132 drives the image chamber 131 to rotate.

[0042] The flange mounting base 133 has a first fixing groove 1331 for placing the ring gear 1311. The ring gear 1311 is located in the first fixing groove 1331. A second lug 1332 is also provided on one side of the flange mounting base 133. The second lug 1332 has a second fixing groove 1333 for placing the first gear 1321. The second fixing groove 1333 communicates with the first fixing groove 1331. The first fixing groove 1331 is used to install the ring gear 1311, and the second fixing groove 1333 is used to install the first gear 1321, so that the ring gear 1311 can rotate in the first fixing groove 1331 and the first gear 1321 can rotate in the second fixing groove 1333. When the second motor 132 drives the first gear 1321 to rotate, the first gear 1321 rotates in the second fixing groove 1333. The rotation of the first gear 1321 drives the ring gear 1311 to rotate in the first fixing groove 1331, so as to realize the rotation of the image chamber 131.

[0043] The image chamber 131 is also provided with a first fixing protrusion on its side wall. The first fixing protrusion is provided with a second through hole communicating with the image chamber 131. The scanning camera 135 is mounted on the first fixing protrusion. On the one hand, the first fixing protrusion is used to position the scanning camera 135. On the other hand, placing the scanning camera 135 on the first fixing protrusion makes it easy to fix the scanning camera 135 on the image chamber.

[0044] Please refer to Figure 10 and Figure 11 , Figure 10 This is a top view of the scanner for the automatic key scanning device of the present invention. Figure 11 for Figure 10 In the cross-sectional view along the cutting line BB, a backlight plate 136 is also provided at the end of the image compartment 131 away from the fixing plate 121. The backlight plate 136 is fixed on the inner side wall of the image compartment 131 and is electrically connected to the control board 134. The backlight plate 136 is used to provide a light source. When scanning the key, the control board 134 controls the backlight plate 136 to emit light to provide illumination for the image compartment 131, so that the scanning camera 135 can scan the key.

[0045] The image chamber 131 is provided with a plurality of second fixing protrusions at the end away from the fixing plate 121. The second fixing protrusions are located on the outside of the image chamber 131. The second fixing protrusions and the backlight plate 136 are respectively located on both sides of the side wall of the image chamber 131. The control plate 134 is mounted on the second fixing protrusions. The second fixing protrusions are used to mount the control plate 134, to prevent the control plate 134 from directly contacting the image chamber 131, and to dissipate heat from the control plate 134 to prevent the control plate 134 from overheating.

[0046] Both the clamping plate 122 and the fixing plate 121 have concave arc-shaped grooves 1211 on their outer sides. The arc-shaped grooves 1211 are located within the range of the first through hole 111. The arc-shaped grooves 1211 are used to facilitate the user to insert the key between the clamping plate 122 and the top wall of the notch, so as to facilitate the key insertion and play a guiding role.

[0047] Working principle: When scanning the key, the user first inserts the front part of the key into the image chamber 131, and the tail part of the key is placed between the clamping plate 122 and the top wall of the notch. The control board 134 controls the first motor 1231 to start, and the first motor 1231 drives the lead screw 1234 to rotate. The rotation of the lead screw 1234 drives the pressing block 1235 to move in the through groove 1223, so that the pressing block 1235 presses the limiting block 1221. The pressing block 1235 moves from the second inclined surface 122 of the limiting block 1221. When the bottom of the clamping plate 122 moves, under the action of the spring 1233, the pressing block 1235 moves downward and towards the key. When the bottom of the clamping plate 122 is in contact with the key, the clamping plate 122 continues to move downward. Under the action of the spring 1233, the clamping plate 122 continues to apply pressure to the key. The spring 1233 deforms and will not directly damage the key. When the pressing block 1235 moves to the predetermined position, the first motor 1231 stops moving to clamp the key between the clamping plate 122 and the key. Between the top walls of the notch, the control board 134 further controls the backlight panel 136 to emit light, providing a light source for the image compartment 131. At the same time, the control board 134 drives the scanning camera 135 to turn on and the second motor 132 to start. The scanning camera 135 scans the key that has entered the image compartment 131. The second motor 132 starts and drives the first gear 1321 to rotate. The rotation of the first gear 1321 drives the ring gear 1311 to rotate. Since the ring gear 1311 is part of the image compartment 131, the image compartment 131 rotates with the ring gear 1311. The scanning camera 135 is fixed on the side wall of the image compartment 131. The scanning camera 135 rotates with the image compartment 131, so that the scanning camera 135 rotates around the key and scans it, thereby performing a full scan of the key. The data scanned by the scanning camera 135 is processed by the control board 134 to generate a 3D model, avoiding the flaws caused by the key model formed by image stitching, thereby improving the accuracy of key matching for users.

[0048] In this preferred embodiment, the automatic key scanner inserts the front part of the key into the image chamber during scanning. The first drive component drives the clamping plate to clamp the key in cooperation with the top wall of the notch. The scanning camera scans the key in the image chamber. During the scanning process, the second drive component drives the image chamber to rotate, and the image chamber drives the scanning camera to rotate, scanning the key from all directions. This avoids defects caused by key models formed by image stitching, thereby improving the accuracy of key matching for users.

[0049] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
