[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, a flexible barcode scanning mechanism provided in one embodiment of this application is disposed at a barcode scanning station, which is used to fix the product 4 to be scanned. The flexible barcode scanning mechanism includes:

[0039] The barcode scanner 1 has its scanning head facing the front of the product 4, and is used to directly acquire the identifiable electronic tag 40 located on the front.

[0040] The reflective component 3 is located on the side of the barcode scanning station and is used to reflect the image of the identifiable electronic tag 40 located on the side of the product 4 into the field of view of the scanning head.

[0041] When the identifiable electronic tag 40 of product 4 is located on the front or side of product 4, it can be scanned and acquired by the barcode scanner 1.

[0042] Figure 1 The fixing structure of product 4 is not shown. For example, product 4 is positioned on a positioning fixture with its front facing up. The barcode scanner 1 is located above product 4 with its scanning head facing down, opposite to the front of product 4.

[0043] Figure 1 The image shows different locations where the identifiable electronic tag 40 can be set, such as a QR code or a barcode.

[0044] When the product structure changes and the position of the identifiable electronic tag 40 also changes, the scanner 1 can still quickly acquire the identifiable electronic tag 40, avoiding the repositioning of the product 4 and the need to change the orientation of the scanning head.

[0045] By setting a reflecting component 3 at the code scanning station, the image of the identifiable electronic tag 40 on the side of the product 4 is reflected into the field of view of the scanning head, so that a plurality of identifiable electronic tags 40 in different directions can be adapted by one code scanner 1 with a fixed scanning direction, the automatic information acquisition of the fixedly placed product 4 is realized, manual removal of the device and repositioning are avoided, the operation process is simplified, the scanning efficiency is improved, the accuracy of the scanning result is ensured, and the overall automation level and work efficiency of the production line are improved.

[0046] In an exemplary embodiment, as shown in Figure 5 , the number of products 4 is multiple, and the products 4 are placed side by side at the code scanning station. The orientations of the identifiable electronic tags 40 on the products 4 are consistent and opposite to the reflecting component 3.

[0047] When a plurality of products 4 of the same type are scanned, the products 4 need to be placed away from the reflecting component 3, and after the scanning is completed, the second product 4 is placed between the first product 4 and the reflecting component 3, and the same is repeated for the scanning of the plurality of products 4. After the second product 4 is placed, the first product 4 can be removed and transferred to the next station. The flexible code scanning mechanism can be applied to the scanning of multiple products 4, improving the transfer efficiency of the products 4.

[0048] In an exemplary embodiment, as shown in Figure 1 , Figure 2 , the number of reflecting components 3 is multiple, and the reflecting components 3 are distributed in different directions of the side of the product 4. When the product 4 has multiple sides and the identifiable electronic tags 40 can be provided on the multiple sides, the orientations of the reflecting components 3 are set according to the requirements, so that the flexible code scanning mechanism can be compatible with the acquisition of the identifiable electronic tags 40 in multiple directions.

[0049] Of course, in other embodiments, the reflecting component 3 can also be a ring-shaped reflecting structure surrounding the outer periphery of the code scanning station.

[0050] Exemplarily, the structure of a single reflecting component 3 includes a bracket 32 and a plane mirror 31. The bracket 32 is used to fix the plane mirror 31 and set the plane mirror 31 at an angle with the side of the product 4, so that the image of the identifiable electronic tag 40 on the side is reflected into the field of view of the scanning head.

[0051] When the angle between the front and the side of the product 4 is ninety degrees, the angle between the plane mirror 31 and the side of the product 4 is forty-five degrees, as shown in Figure 2 .

[0052] In an exemplary embodiment, as shown in Figure 1 , Figure 2 , the drive mechanism 2 is further included, and the drive mechanism 2 is used to drive the code scanner 1 to move and change the position of the code scanner 1 relative to the product 4, so that the image of the electronic tag is located in the field of view of the scanning head.

[0053] In another exemplary embodiment, as shown in Figure 1 , Figure 4 , Figure 5 The driving mechanism 2 is structured to include a base 24, on which the code scanner 1 is slidingly mounted, and a driver 21, which is in driving connection with the code scanner 1 and is used to drive the code scanner 1 to move in a straight line.

[0054] In the case where the field of view of the code scanner 1 is small, a simple straight-line driving mechanism is adopted, and only the code scanner 1 needs to be driven to move in a plane, so that the code scanning of various products 4 can be realized, and the overall manufacturing cost of the flexible code scanning mechanism is reduced.

[0055] The straight-line moving direction of the driving mechanism 2 corresponds to the image reflection points of the two reflecting components 3, and when the code scanner 1 moves in the straight-line direction and the scanning head corresponds to an image reflection point, the identifiable electronic label 40 located on one side of the product 4 is acquired.

[0056] The number of the corresponding reflecting components 3 is two, and the arrangement direction of the reflecting components 3, the code scanning station, and the reflecting components 3 is consistent with the moving direction of the code scanner 1, as shown in Figure 5 .

[0057] When the flexible code scanning mechanism is adapted to products 4 of different structural forms, the product 4 is placed in the code scanning station, and only the identifiable electronic label 40 needs to be directed towards a reflecting component 3, so that the flexible code scanning mechanism has a certain flexibility under the consideration of the overall structural size and cost, and is suitable for various situations.

[0058] The code scanner 1 is driven to move in a straight line, so that different products 4 correspond to different positions of the code scanner 1, which can reduce the field of view of the code scanner 1 and reduce the purchase cost of the code scanner 1, and on the other hand, the model type of the product 4 can be controlled to correspond to the position of the code scanner 1, so that the product 4 is more accurately corresponded, and the product information input process in the automatic production process is facilitated.

[0059] The middle position of the straight-line moving direction of the driving mechanism 2 corresponds to the front code scanning position of the product 4, and the number of the front code scanning positions is consistent with the number of the products 4.

[0060] When the number of the products 4 in the code scanning station is multiple, the multiple products 4 are placed side by side, and the arrangement direction of the products 4 is consistent with the moving direction of the driving mechanism 2.

[0061] The code scanner 1 can be quickly and accurately moved in a plane direction (specifically, a horizontal plane), which not only solves the problem of manually moving and placing the product 4 to align the traditional small-view code scanner 1, reduces the time consumption of manual operation, but also can accurately identify two-dimensional codes in different positions and angles, ensures the accuracy of scanning, and greatly improves the work efficiency.

[0062] As shown in the example, Figure 4 The driver 21 is a motor, the base 24 is rotationally installed with a transmission belt 22, the transmission belt 22 is fixedly connected with the code scanner 1, and the driver 21 drives the transmission belt 22 to rotate, thereby driving the code scanner 1 to move.

[0063] The code scanner 1 is provided with a sliding block, which is slidably connected with a sliding rail 23 on the base 24; the base 24 is provided with a plurality of sensors for detecting the limit position and zero position of the code scanner 1, and the movement position of the code scanner 1 is recorded by motor pulses.

[0064] In an exemplary embodiment, the present application provides a test device, which comprises the flexible code scanning mechanism according to any one of the above embodiments, the flexible code scanning mechanism is arranged at a feeding station of the test device, and the test device further comprises an automatic handling mechanism, which is used for handling the product 4 to be scanned to the code scanning station, and handling the scanned product 4 to a test station.

[0065] The flexible code scanning mechanism can make the automatic handling mechanism have the function of fixedly placing the product 4, thereby reducing the manufacturing cost of the automatic handling mechanism, improving the feeding and discharging handling efficiency and information acquisition efficiency of the product 4, avoiding the use of high-cost equipment such as multiple code scanners or complex mechanical arms, and saving the space and cost of the test device.
