[0072] See also Figures 1 to 4The embodiment of the present invention provides a character recognition device 100, the character recognition device 100 includes a cabinet 10 and a character recognition component 20 installed in the cabinet 10, the character recognition component 20 includes an image acquisition unit 21, a processing unit 22 connected to the image acquisition unit 21, and a storage unit 23 connected to the processing unit 22, wherein the image acquisition unit 21 is used to acquire image information of a to-be-recognized area 200 (for example, in this embodiment, the to-be-recognized area 200 is an area in a mobile phone card tray where an IMEI number is printed), the processing unit 22 is used to recognize character information in the image information (for example, in this embodiment, the numbers or letters are IMEI numbers), and the storage unit 23 is used to store the character information. By setting the image acquisition unit 21 and the processing unit 22, manual recognition and manual input into the storage unit 23 are avoided, thereby effectively improving the speed and accuracy of storing the IMEI number into the storage unit 23.

[0073] In this embodiment, the character recognition component 20 further includes a signal output unit 24 connected to the processing unit 22, and the signal output unit 24 includes an indicator light 241. The processing unit 22 is also used to determine whether the character information is incorrect. The indicator light 241 is used to display the judgment result of the processing unit 22. For example, when the character information is correct, the indicator light 241 displays green, and when the character information is incorrect, the indicator light 241 displays red. The operator can perform the next operation according to the indication of the indicator light 241. The signal output unit 24 can be installed on the outside of the cabinet 10 for easy observation by the user.

[0074] See also Figure 5 and Figure 6 In this embodiment, the image acquisition unit 21 includes a fixed bracket 211, a light source 212 disposed on one side of the fixed bracket 211, an image sensor 213 disposed on the other side of the fixed bracket 211 opposite to the light source 212, and a lens 214 disposed between the light source 212 and the image sensor 213. The fixed bracket 211 is fixed to the cabinet 10. The light source 212 is used to emit light toward the area to be identified 200. After the light is irradiated to the area to be identified 200, it will be reflected by the area to be identified 200. The lens 214 is used to collect the reflected light from the area to be identified 200, and the image sensor 213 (for example, CCD) is used to convert the reflected light into the image information. In this embodiment, the image sensor 213 is a charge coupled device (CCD).

[0075] Generally speaking, the color of the area to be identified 200 is different (for example, the colors of mobile phone card trays of different colors are different), mainly light colors such as white and blue or dark colors such as black and yellow. The character information includes white characters and characters of other colors. In this embodiment, the light source 212 includes a spherical integrating light source 2121, and the spherical integrating light source 2121 is used to emit a first light toward the area to be identified 200. The image information obtained by acquiring the reflected light formed by the first light reflected by the area to be identified 200 and the image sensor 213 can be used to identify the characters of the area to be identified 200 of light color. The spherical integrating light source 2121 includes a hemispherical shell 2122 and a plurality of light-emitting components (such as LED lamp beads, not shown) arranged at the edge of the shell 2122. The interior of the shell 2122 is coated with a reflective layer (not shown). The reflective layer reflects the light emitted by the plurality of light-emitting components, so that the spherical integrating light source 2121 can also achieve multi-directional illumination, thereby avoiding the adverse effect on the image information caused by the surface undulations of the area to be identified 200 or the surface reflection of the area to be identified 200. A through hole 2123 is provided on the top of the shell 2122, and the through hole 2123 is opposite to the end of the lens 214 away from the image sensor 213. The light reflected by the area to be identified 200 enters the lens 214 through the through hole 2123.

[0076] In this embodiment, the light source 212 also includes an annular light source 2124, which is used to emit a second light toward the area to be identified 200. The image information obtained by acquiring the reflected light formed by the second light being reflected by the area to be identified 200 of dark color by the image sensor 213 can be used to identify the characters of the area to be identified 200 of dark color. At the same time, the annular light source 2124 is arranged below the multiple light-emitting elements of the spherical integrating light source 2121. The annular light source 2124 has a large illumination area and a low illumination angle, which is conducive to the positioning of the area to be identified 200.

[0077] In this embodiment, the spherical integrating light source 2121 or the annular light source 2124 may be switched according to the different colors of the to-be-recognized area 200 , so that the image acquisition unit 21 can better recognize the character information in the to-be-recognized area 200 of different colors.

[0078] See also Figure 1 and Figure 3In the present embodiment, the character recognition device 100 further includes a guide rail 30 and a carrier 31 movably disposed on the guide rail 30, and a driving motor 242 electrically connected to the processing unit 22 is disposed between the carrier 31 and the guide rail 30. The driving motor 242 is used to drive the carrier 31 to move on the guide rail 30. Among them, the guide rail 30 is provided with a discharge position 301, an identification position 302 and a grabbing position 303 in sequence in its extension direction, and the identification position 302 is provided with a first sensor 3021, and the grabbing position 303 is provided with a second sensor 3031. The first sensor 3021 and the second sensor 3031 are both connected to the processing unit 22, and the first sensor 3021 or the second sensor 3031 is used to sense whether the carrier 31 is in the identification position 302 or the grabbing position 303, and the discharge position 301 is used to place a piece to be tested 300 in the carrier 31 (in the present embodiment In the example, the test object 300 is a mobile phone, and the mobile phone includes a to-be-tested area 200 where an IMEI number is printed, and the character recognition component 20 is arranged above the recognition position 302, so that the image acquisition unit 21 is facing the to-be-tested area 200 of the test object 300, and the grab position 303 is used to grab the test object 300 to enter the next test unit 400, and the test unit 400 is used to plug the test object 300 to obtain the IMEI number stored in the test object 300, and determine whether the IMEI number is the same as the character information stored in the storage unit 23. Among them, the first sensor 3021 and the second sensor 3031 can be position sensors. During the specific operation, the operator loads a test piece 300 into the carrier 31 at the discharge position 301, and the processing unit 22 issues an actuation command to the drive motor 242, so that the carrier 31 loaded with the test piece 300 starts to move from the discharge position 301 until the first sensor 3021 senses that the carrier 31 moves to the identification position 302, and the processing unit 22 issues a stop command to the drive motor 242, and the carrier 31 stays at the identification position 302, and waits for the character recognition component 20 to complete the identification of the test piece 300. The character information of the to-be-identified area 200 is recognized and stored, and the processing unit 22 again gives an actuation instruction to the drive motor 242 until the second sensor 3031 senses that the carrier 31 moves to the grabbing position 303, and the processing unit 22 again issues a stop instruction to the drive motor 242, and the carrier 31 stays at the grabbing position 303, and waits for the to-be-tested piece 300 in the carrier 31 to enter the next test unit 400, and the processing unit 22 issues an actuation instruction to the drive motor 242, so that the carrier 31 returns to the discharge position 301.When the processing unit 22 senses that a fault occurs at the identification position 302 or the gripping position 303 (for example, the character information determined by the processing unit 22 at the identification position 302 is incorrect), the processing unit 22 gives an actuation command to the drive motor 242, so that the carrier 31 carrying the test piece 300 returns to the discharge position 301, and the operator further confirms.

[0079] In this embodiment, please refer to Figure 7 The test unit 400 includes at least one test component 402 arranged side by side, a plug-in component 401 arranged at one end of each of the test components 402, and at least one grabbing component 403 arranged above the test component 402. Each of the test components 402 includes a slide rail 4021 and a test platform 4022 movably arranged on the slide rail 4021. The grabbing component 403 is used to grab the test piece 300 from the carrier 31 from the grabbing position 303 and place it on the test platform 4022. The test platform 4022 is used to transport the test piece 300 to the vicinity of the plug-in component 401. The plug-in component 401 is used to plug the test piece 300 and transmit the EMEI number stored in the test piece 300 to the processing unit 22. The processing unit 22 compares the EMEI number with the character information stored in the storage unit 23.

[0080] In other embodiments of the present invention, the slide rail of the test component 402 may be omitted, as long as the plug-in component 401 can be plugged into the test piece 300 on the test platform 4022 .

[0081] In this example, see Figure 7 The plug assembly 401 includes a base 4011, a plug board 4012 movably fixed on the base 4011, a plug connector 4013 movably fixed on the plug board 4012, and a cylinder 4014 fixed on the base 4011 for driving the plug board 4012. The cylinder 4014 can push the base 4011 to move along the slide rail 4021, so as to facilitate the alignment of the plug connector 4013 and the test piece 300 in the direction of the slide rail 4021. The plug connector 4013 can move on the plug board 4012 in a direction perpendicular to the slide rail 4021, so as to facilitate the alignment of the plug connector 4013 and the test piece 300 in a direction perpendicular to the slide rail 4021.

[0082] See also Figure 4In this embodiment, the carrier 31 includes a receiving portion 311 and a pre-pushing portion 312. The receiving portion 311 is used to receive the test piece 300 having a to-be-recognized area 200. The pre-pushing portion 312 includes a slider 3121, a push block 3122 detachably fixed to the slider 3121, and a positioning block 3123 fixed below the receiving portion 311. The positioning block 3123 is fixed below the receiving portion 311 facing the push piece 3126. The positioning block 3123 is used to block the push piece 3126 when the push piece 3126 pushes the to-be-recognized area 200 to a predetermined position. This is beneficial for the image acquisition unit 21 to recognize the image information of the to-be-recognized area 200.

[0083] Specifically, the slider 3121 can be movably accommodated below the accommodating portion 311 along the width direction of the accommodating portion 311, and a plurality of first protrusions 3124 are arranged on the side of the slider 3121 close to the area to be identified 200. The push block 3122 includes a fixing plate 3125 and an L-shaped push plate 3126 extending perpendicularly to the fixing plate 3125 toward the area to be identified 200. A plurality of first openings 3127 matching the protrusions 3124 are arranged through the fixing plate 3125. The push block 3122 can be fixed and disassembled by inserting or pushing the first protrusions 3124 into or out of the first openings 3127. At the same time, the distance between the push plate 3126 and the area to be identified 200 along the width direction of the accommodating portion 311 can be adjusted by adjusting the first protrusions 3124 to be inserted into different first openings 3127.

[0084] In other embodiments of the present invention, the fixing plate 3125 includes a connecting plate (not shown) extending vertically from one end close to the accommodating portion 311, and the pushing plate 3126 can be movably fixed to the connecting plate. Specifically, the connecting plate is provided with a plurality of second protrusions (not shown), and the pushing plate 3126 is provided with a plurality of second openings at positions corresponding to the second protrusions. By adjusting the second protrusions to insert into different second openings, the distance between the pushing plate 3126 and the area to be identified 200 along the length direction of the accommodating portion 311 can be adjusted. During the specific operation, the operator exposes the area to be identified 200 (for example, the area in the mobile phone card tray where the IMEI number should be) from the test piece 300, and then loads the test piece 300 into the receiving portion 311, so that the area to be identified 200 is opposite to the push piece 3126. Then, the operator pushes the slider 3121, and the slider 3121 drives the push piece 3126, and the push piece 3126 pushes the area to be identified 200 until the positioning block 3123 blocks the push piece 3126. At this time, the area to be identified 200 is in the best position for facilitating the operation of the image acquisition unit 21.
