The application provides a display screen code scanning method, referring to fig. 1-4, the method is applied to a code scanning system 1, the code scanning system 1 comprises a positioning device 3, a code reader 5, a carrier 4 and a host 6, and the code reader 5 is electrically connected with the host 6; the method comprises the following steps:
s10: mounting the carrier 4 carrying a plurality of display screens 9 on an upper positioning plate 32 of the positioning device 3; the upper positioning plate 32 is provided with a scanning window 321, and the scanning window 321 exposes at least two bar codes on the display screen 9.
In this embodiment, the display screen 9 is a display screen of a barcode to be scanned, and in the present application, the display screen 9 mainly refers to a micro display screen, and the display screen 9 is mounted on the carrier 4. The positioning device 3 comprises an upper positioning plate 32 and a lower positioning plate 31, a certain distance is reserved between the upper positioning plate 32 and the lower positioning plate 31, the carrier 4 is installed on the top surface of the upper positioning plate 32, the code reader 5 is installed on the top surface of the lower positioning plate 31, and a scanning window 321 is formed in the upper positioning plate 32.
When the carrier 4 carrying the display screen 9 is mounted on the upper positioning plate 32, the scanning window 321 can expose at least two bar codes on the display screen 9, the bar codes on the display screen 9 are opposite to the code reader 5, the bar codes of the display screen 9 exposed through the scanning window 321 can be scanned at one time through the code reader 5, and the number of bar codes of the display screen 9 required to be scanned at one time can be reasonably set through the scanning window 321.
S11: controlling the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 to scan the bar code on the display screen 9 exposed through the scanning window 321; the scanning range of the code reader 5 covers the scanning window 321.
In this embodiment, after the carrier 4 carrying the display screen 9 is mounted on the upper positioning board 32, the host 6 may control the code reader 5 to scan the bar codes on the display screen 9 exposed through the scanning window 321 in batches. For example, the bar codes of thirty display screens 9 can be exposed through the scanning window 321, and the bar codes of thirty display screens 9 exposed by the scanning window 321 can be scanned at one time by the code reader 5.
S12: the carrier 4 is moved to a preset position, and the code reader 5 is controlled to scan the bar code on the display screen 9 exposed through the scanning window 321.
In this embodiment, the preset position is a preset position in advance, when the carrier 4 moves to the preset position, the display screen 9 scanned in step S11 by the code reader 5 moves to a position no longer exposed by the scanning window 321 along with the carrier 4, and the scanning window 321 exposes at least part of other display screens 9 on the carrier 4 that are not scanned above the code reader 5, and then the bar codes on the display screen 9 exposed by the scanning window 321 are scanned again in batches by the code reader 5. And repeating the step S12 until the bar codes of all the display screens 9 on the carrier 4 are scanned, and then repeating the steps S10-S12 to scan the bar codes of the display screens 9 on the rest carrier plates.
For example, ninety display screens 9 are installed on the carrier 4, the scanning window 321 can expose the bar codes of thirty display screens 9 at a time, after the bar codes of thirty display screens 9 are scanned at a time in step S11, the carrier 4 is moved to a preset position where the bar codes of another thirty display screens 9 which are not scanned by the bar codes can be exposed, and then the bar codes of the thirty display screens 9 exposed by the scanning window 321 are scanned in batches by the code reader 5. And repeating the step S12, moving the carrier 4 to a preset position capable of exposing the bar codes of the rest thirty display screens 9 through the scanning window 321, and finally scanning the bar codes of the rest thirty display screens 9 in batches through the code reader 5. Thus, the bar codes of all the display screens 9 on the carrier plate can be scanned three times.
Based on the above design, compared with the prior art that only one bar code on one display screen 9 can be scanned at a time, the application can scan the bar codes on a plurality of display screens 9 exposed by the scanning window 321 in batch at a time through the code reader 5, when the code reader 5 scans the bar codes on the display screen 9 for the first time, the carrier 4 is quickly moved to a preset position, and then the bar codes on the display screen 9 exposed by the scanning window 321 are scanned again in batch through the code reader 5. In this way, by setting the preset position for the movement of the carrier 4 and performing batch scanning on the bar codes of the display screen 9 exposed by the scanning window 321 through the code reader 5, the scanning efficiency of the bar codes on the display screen 9 can be greatly improved.
In some embodiments, referring to fig. 5, the step of controlling the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 to scan the bar code on the display screen 9 exposed through the scanning window 321 includes:
s111: the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 is adjusted.
S112: based on the adjusted code reader 5, the bar code on the display screen 9 exposed by the scanning window 321 is scanned.
In this embodiment, before the bar codes on the display screen 9 are scanned by the code reader 5, the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 is adjusted so as to scan the bar codes on all the display screen 9 exposed by the scanning window 321 more clearly. In this way, the scanning quality of the barcode on the display screen 9 exposed through the scanning window 321 by the barcode reader 5 can be improved.
In some embodiments, referring again to fig. 4, the positioning device 3 further includes a frame 33 and a spacer 34, the spacer 34 is mounted on a top surface of the frame 33, the upper positioning plate 32 is mounted on a top surface of the spacer 34, and the lower positioning plate 31 is mounted on a lower portion of the frame 33. The cushion block 34 may be connected to the upper positioning plate 32 and the frame 33 by a positioning pin, a bolt, and the lower positioning plate 31 may be mounted on the frame 33 by a bolt. The number of the cushion blocks 34 is preferably two, and the two cushion blocks 34 may be symmetrically disposed at two sides of the scanning window 321.
The step of adjusting the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 includes: the distance between the upper positioning plate 32 and the lower positioning plate 31 is adjusted through the cushion block 34, so as to adjust the distance between the code reader 5 and the bar code of the display screen 9.
The distance between the upper positioning plate 32 and the lower positioning plate 31 may not be too large or too small to clearly scan the bar code on the display screen 9 exposed by the scanning window 321, so that the distance between the upper positioning plate 32 and the lower positioning plate 31 needs to be adjusted to be suitable in order to adjust the distance between the code reader 5 and the bar code on the display screen 9. For example, the vertical distance between the upper positioning plate 32 and the lower positioning plate 31 may be set to 65mm to 75mm. Thus, the bar code of the display screen 9 exposed by the scanning window 321 can be scanned more clearly and more comprehensively by the code reader 5.
Preferably, referring to fig. 6, the cushion block 34 includes a first cushion block 341, a second cushion block 343, and a cylinder 342 located between the first cushion block 341 and the second cushion block 343, the cylinder 342 is mounted on the top surface of the first cushion block 341, and a piston rod of the cylinder 342 is connected with the bottom surface of the second cushion block 343.
In this embodiment, when the piston rod of the cylinder 342 extends, the piston rod of the cylinder 342 sequentially drives the second base plate 343 and the upper positioning plate 32 to move away from the lower positioning plate 31, so as to increase the distance between the upper positioning plate 32 and the lower positioning plate 31. When the piston rod of the cylinder 342 is retracted, the piston rod of the cylinder 342 sequentially drives the second pad 343 and the upper positioning plate 32 to move in a direction approaching the lower positioning plate 31, so that the distance between the upper positioning plate 32 and the lower positioning plate 31 can be reduced. In this way, it is possible to more conveniently adjust the distance between the upper positioning plate 32 and the lower positioning plate 31, and thus it is possible to more conveniently adjust the distance between the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 and the code reader 5.
In some embodiments, please refer to fig. 2 again, the code scanning system 1 further includes a code scanning conversion device and a warehouse system 8, the warehouse system 8 is electrically connected with the host 6, the scan conversion device 7 has two USB interfaces, one USB interface is electrically connected with the host 6, and the connection manner of the other USB interface is in two cases: when the code scanning position is calibrated at the code reader 5, the other USB interface is electrically connected with the code reader 5; after the calibration of the code scanning position is completed, when the warehousing system 8 scans codes in batches and stores data, the other USB interface is electrically connected with the warehousing system 8.
Referring to fig. 7, the step of adjusting the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 includes:
s1111: and connecting the code scanning conversion device with the code reader 5.
One USB interface of the code scanning conversion device is electrically connected with the host 6, and the other USB interface is electrically connected with the code reader 5.
S1112: the code reader 5 is adjusted to generate a scanning template.

S1122: based on the scanning stencil, the code reader 5 mounted on the lower positioning plate 31 of the positioning device 3 is controlled to scan the bar code on the display screen 9 exposed through the scanning window 321.
Based on the scanning template loaded into the warehousing system 8, the warehousing system 8 controls the code reader 5 to scan the bar code on the display screen 9 exposed by the scanning window 321. Thus, since the scanning template is obtained based on the fact that the barcode reader 5 can clearly and comprehensively scan the barcode of the display screen 9 exposed by the scanning window 321, the barcode reader 5 can scan the barcode of the display screen 9 with higher quality based on the scanning template. Since the same type of display screen 9 can be based on one scanning template, the scanning template is not required to be generated when the bar codes of the same type of display screen 9 are scanned in the later period, so that the efficiency of scanning the bar codes of the display screen 9 can be further improved.
In some embodiments, referring to fig. 9, the step of adjusting the code reader 5 to generate a scan template includes:
s11121: the frame of the bar code image of the display screen 9 scanned by the code reader 5 is adjusted.
The barcode image of the display screen 9 on the carrier 4 is scanned by the code reader 5, and then the frame of the barcode image is adjusted to adjust the size and definition of the barcode image, for example, the focal length of the code reader 5 is adjusted until the code reader 5 can clearly scan the barcode of the display screen 9 on the carrier 4.
S11122: and adjusting the signal transmitted by the code reader 5.
The signal emitted by the code reader 5 is adjusted to ensure that the signal emitted by the code reader 5 can cover the bar codes of all the display screens 9 exposed by the scanning window 321.

And detecting whether the code reader 5 can clearly and completely read the bar code of the display screen 9 exposed by the scanning window 321, and if not, repeating the steps S11121-S11123.
S11124: if so, generating a scanning template.
When the code reader 5 can read the bar code of the display screen 9 exposed by the scanning window 321 clearly and completely, the scanning template is generated. Thus, by reading the definition and the comprehensiveness of the bar code of the display screen 9 from the code reader 5, a scanning template with higher precision can be generated, so that the bar code of the display screen 9 can be scanned more efficiently and accurately.
In some embodiments, referring to fig. 10, after the step of scanning the bar code on the display screen 9 exposed by the scanning window 321 based on the adjusted code reader 5, the method further includes:
s113: the scanning information of the bar code on the code reader 5 is recorded and stored by the warehouse system 8.

In some embodiments, the positioning device 3 further comprises a positioning assembly 35 mounted on the top surface of the upper positioning plate 32; the mounting of the carrier 4 carrying the display screens 9 on the upper positioning plate 32 of the positioning device 3 comprises the following steps: the carrier 4 carrying the plurality of display screens 9 is positioned on the upper positioning plate 32 of the positioning device 3 by the positioning assembly 35.
In this embodiment, when the positioning component 35 is used to mount the carrier 4 on the upper positioning board 32, the scanning window 321 may just expose the bar code of the display screen 9 on the carrier 4, and the positioning component 35 may be used to move the carrier 4 to the preset position more accurately, so that the code reader 5 may scan the bar code of the next batch of display screens 9 more conveniently.
In some embodiments, referring to fig. 4 again, the positioning assembly 35 includes a first L-shaped positioning block 351, a second L-shaped positioning block 353, and a plurality of bar-shaped positioning blocks 352 disposed between the first L-shaped positioning block 351 and the second L-shaped positioning block 353, wherein the first L-shaped positioning block 351, the bar-shaped positioning block 352, and the second L-shaped positioning block 353 are sequentially arranged along the moving direction of the carrier 4.
The step of positioning the carrier 4 carrying the plurality of display screens 9 on the upper positioning plate 32 of the positioning device 3 by the positioning assembly 35 includes: the carrier 4 carrying the plurality of display screens 9 is positioned on the upper positioning plate 32 of the positioning device 3 through the first L-shaped positioning block 351 and the strip-shaped positioning block 352.
The step of moving the carrier 4 to a preset position and controlling the code reader 5 to scan the bar code on the display screen 9 exposed through the scanning window 321 includes: the carrier 4 is moved to contact with the second L-shaped positioning block 353, and the code reader 5 is controlled to scan the bar code on the display screen 9 exposed through the scanning window 321.
In this embodiment, the right-angle sides of the first L-shaped positioning block 351 and the second L-shaped positioning block 353 face the carrier 4, and the distance between two adjacent bar-shaped positioning blocks 352 is smaller than the width of the carrier 4, so that the carrier 4 can be prevented from sliding out from the gap between two adjacent bar-shaped positioning blocks 352 when the carrier 4 slides along the bar-shaped positioning blocks 352. The first L-shaped positioning block, the plurality of bar-shaped positioning blocks 352, and the second L-shaped positioning block 353 may be integrally formed.
Referring to fig. 3 again, when the carrier 4 carrying the display screen 9 is placed on the upper positioning plate 32, a side of the carrier 4, which is close to the first L-shaped positioning block 351, abuts against the first L-shaped positioning block 351, and at this time, the bar codes of the display screen 9 on the carrier 4 are exposed through the scanning window 321 and face the code reader 5, and then the bar codes of the display screen 9 exposed through the scanning window 321 are scanned by the code reader 5.
Referring to fig. 12, after the barcode of the display screen 9 exposed by the scanning window 321 is scanned by the code reader 5, the carrier 4 is moved in the direction of the second L-shaped positioning block 353 (i.e. in the direction indicated by the arrow in fig. 12), for example, the carrier 4 may be manually moved to abut against the second L-shaped positioning block 353. When the carrier 4 abuts against the second L-shaped positioning block 353, the two-dimensional code of the display screen 9 exposed by the scanning window 321 is not scanned by the code reader 5.
For example, sixty display screens 9 are carried on the carrier 4, when the carrier 4 abuts against the first L-shaped positioning block 351, the bar codes of thirty display screens 9 on the carrier 4 are exposed by the scanning window 321, and the code reader 5 can scan the exposed bar codes of thirty display screens 9 in batches for the first time. When the carrier 4 abuts against the second L-shaped positioning block 353, all the scanned display screens 9 on the carrier 4 are moved to the positions not exposed by the scanning window 321, the bar codes of the remaining thirty non-scanned display screens 9 are just all exposed by the scanning window 321, and the code reader 5 can scan the bar codes of the remaining thirty display screens 9 in batch for the second time. In this way, the display screen 9 on the carrier 4 can be accurately positioned by the first L-shaped positioning block 351, the bar-shaped positioning block 352 and the second L-shaped positioning block 353, so that the scanning efficiency and the scanning quality of the bar code of the display screen 9 can be further improved.
In the present embodiment, the number of times the carrier 4 moves from the first L-shaped positioning block 351 to the second L-shaped positioning block 353 is not limited, and the carrier 4 may also move in a direction perpendicular to the direction indicated by the arrow in fig. 11. In summary, when the carrier 4 is required to move to the preset position, the barcodes of all the display screens 9 scanned last time are no longer exposed by the scanning window 321, and the barcodes of the display screens 9 not scanned are just exposed by the scanning window 321. Therefore, the carrier 4 can be moved to the preset position more accurately, so that the bar code of the display screen 9 on the carrier 4 can be scanned more efficiently.
Preferably, referring to fig. 13, the side surfaces of the first L-shaped positioning block 351, the strip-shaped positioning block 352 and the second L-shaped positioning block 353 are respectively provided with a chute 10, the carrier 4 is provided with a protrusion 41, and the protrusion 41 is slidably connected with the chute 10. In this way, the carrier 4 can be moved along the preset route more stably, so that the barcode of the display screen 9 can be exposed more accurately by the scanning window 321.
In some embodiments, referring to fig. 14, the carrier 4 is provided with a plurality of mounting slots 42 arranged in an array, and a scanning slot 43 in communication with the mounting slots 42.
The step of mounting the carrier 4 carrying the plurality of display screens 9 on the upper positioning plate 32 of the positioning device 3 is preceded by the following steps: several display screens 9 are installed in the installation groove 42 one by one, and the bar codes on the display screens 9 are exposed through the scanning groove 43.
In this embodiment, since the mounting grooves 42 are arranged in a layer array, when the display screen 9 is mounted in the mounting groove 42, the display screen 9 is also arranged in a layer array. The side of the display screen 9 with the bar code faces the scanning groove 43, and the bar code of the display screen 9 is exposed through the scanning groove 43, so that the bar code of the display screen 9 faces the code reader 5. Thus, the bar codes of the display screen 9 can be scanned in batches by the code reader 5 more conveniently.
Preferably, referring to fig. 15, a step structure is formed between the mounting groove 42 and the scanning groove 43, the edge of the display screen 9 is placed on the mounting groove 42, and one side of the display screen 9 with bar codes is suspended in the scanning groove 43. In this way, the side of the display screen 9 with the bar code can be prevented from contacting with the carrier 4, so that the damage of the carrier 4 to the bar code of the display screen 9 and corresponding components can be prevented as much as possible.
In summary, compared with the prior art in which only one barcode on the display screen 9 can be scanned at a time, the barcode reader 5 can scan the barcodes on the plurality of display screens 9 exposed by the scanning window 321 in batch at a time, when the barcode reader 5 scans the barcodes on the display screen 9 for the first time, the carrier 4 is quickly moved to a preset position, and then the barcodes on the display screen 9 exposed by the scanning window 321 are scanned again in batch by the barcode reader 5. In this way, by setting the preset position for the movement of the carrier 4 and performing batch scanning on the bar codes of the display screen 9 exposed by the scanning window 321 through the code reader 5, the scanning efficiency of the bar codes on the display screen 9 can be greatly improved.
The above description is merely illustrative of various embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the scope of the present application, and the application is intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
