Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the dual-channel barcode scanning device 100 of some embodiments of this application includes two conveying mechanisms 110 and a barcode scanning module 120. The two conveying mechanisms 110 are arranged side by side, and each conveying mechanism 110 is used to convey multiple workpieces 300; the barcode scanning module 120 includes two barcode scanning components 121, with each conveying mechanism 110 corresponding to a barcode scanning component 121. The barcode scanning component 121 is disposed on the path of the corresponding conveying mechanism 110, and is used to read the information code of the workpiece conveyed by the corresponding conveying mechanism 110.

[0031] The conveying mechanism 110 conveys the workpiece 300 along the first direction X. Two conveying mechanisms 110 are arranged side by side along the second direction Y. The first direction X and the second direction Y are two mutually perpendicular horizontal directions. The workpiece 300 can be a single battery cell or other types of products that require barcode scanning and sorting.

[0032] The dual-channel barcode scanning device 100 of this application embodiment includes two conveying mechanisms 110, each conveying mechanism 110 having a corresponding barcode scanning component 121. The conveying mechanism 110 can independently convey the workpiece 300 through the corresponding barcode scanning component 121, enabling dual-channel barcode scanning operations, flexibly matching different feeding rhythms, and improving barcode scanning efficiency and workpiece 300 sorting efficiency.

[0033] like Figure 2 As shown, in some embodiments of this application, the barcode scanning module 120 further includes a light shield 122, which is configured to cover the barcode scanning component 121 from above.

[0034] The material of the sunshade 122 can be plastic, resin glass, acrylic sheet, etc.

[0035] Two barcode scanning components 121 can share the same light shield 122, or each barcode scanning component 121 can have its own independent light shield 122. The barcode scanning component 121 is located above the conveying mechanism 110 in the vertical direction Z, and the upper surface of the workpiece 300 is engraved with an information code. The barcode scanning component 121 includes a barcode scanner 1211, the scanning port of the barcode scanner 1211 is set downwards or diagonally downwards in the vertical direction Z, and the light shield 122 covers the barcode scanner 1211 from above.

[0036] This configuration can improve the reflectivity of the workpiece 300 surface and reduce the probability of external light sources entering the barcode scanner via reflection from the workpiece 300, thereby improving the barcode scanner 1211's recognition accuracy of the information code and thus enhancing the scanning accuracy.

[0037] In other embodiments, the barcode scanning component 121 may also be disposed on one side of the conveying mechanism 110 along the second direction Y, the barcode scanner 1211 is horizontally positioned, the workpiece 300 is engraved with information codes on the left or right side, and the light shield 122 covers the barcode scanning component 121 from the side.

[0038] In some embodiments of this application, the reflectivity of the light shield 122 is R, which satisfies: R≤50%.

[0039] Reflectivity R refers to the ratio of the radiant energy reflected from the surface of an object to the total incident radiant energy.

[0040] As an example, the light shield 122 is made of acrylic sheet and is brown in color.

[0041] This configuration reduces the light transmittance of the light shield 122, improves the reflection phenomenon on the surface of the workpiece 300, and reduces the probability of external light sources entering the barcode scanner through reflection, thereby improving scanning accuracy.

[0042] like Figure 2 As shown, in some embodiments of this application, the light shield 122 includes a top wall 1221 and an outer peripheral wall 1222, the outer peripheral wall 1222 extending downward from the edge of the top wall 1221.

[0043] The thickness of the top wall 1221 extends along the vertical direction Z. The top wall 1221 is located on the upper side of the barcode scanning component 121. The outer peripheral wall 1222 extends downward from the edge of the top wall 1221 along the vertical direction Z.

[0044] This configuration allows for the maintenance of unobstructed light at the barcode scanner while minimizing the obstruction of light sources from other directions, thus mitigating the problem of surface reflection on the workpiece 300 that affects scanning accuracy.

[0045] like Figure 2 As shown, in some embodiments of this application, the outer peripheral wall 1222 includes two oppositely arranged first sidewalls 1223 and two oppositely arranged second sidewalls 1224. Each first sidewall 1223 connects to the two second sidewalls 1224. The first sidewalls 1223 extend along the conveying direction of the conveying mechanism 110, and the lower edge of the first sidewall 1223 extends beyond the lower edge of the second sidewall 1224.

[0046] Two first sidewalls 1223 are arranged opposite each other along the second direction Y, and two second sidewalls 1224 are arranged opposite each other along the first direction X. The top wall 1221 is a square plate, and each edge of the square plate corresponds to a sidewall. The length direction of the first sidewall 1223 extends along the first direction X, and the length direction of the second sidewall 1224 extends along the second direction Y.

[0047] The lower side of the first sidewall 1223 has a first edge 1225, and the lower side of the second sidewall 1224 has a second edge 1226. The lower edge of the first sidewall 1223 extending beyond the lower edge of the second sidewall 1224 means that the first edge 1225 is lower than the second edge 1226, that is, the first edge 1225 is closer to the conveying mechanism 110 relative to the second edge 1226.

[0048] This configuration improves the light-blocking effect on both sides of the conveying mechanism 110, thereby increasing scanning accuracy.

[0049] In other embodiments, the top wall 1221 may also be of other shapes, and the edges of the outer peripheral wall 1222 may also be flush.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this application, the dual-channel scanning device 100 includes a frame 130, the scanning module 120 includes a bracket 123, the conveying mechanism 110 is disposed on the frame 130, and the light shield 122 is disposed on the frame 130 through the bracket 123.

[0051] The barcode scanning component 121 can be fixed to the light shield 122, for example, fixed to the first side wall 1223 of the light shield 122; the barcode scanning component 121 can also be fixed to the bracket 123, for example, the bracket 123 can also include two uprights and a crossbar, the two uprights are spaced apart along the first direction X, each upright extends along the vertical direction Z, the bottom of the uprights is installed on the frame 130, the crossbar connects the two uprights along the first direction X, and the barcode scanning component 121 is fixed to the crossbar.

[0052] The frame 130 also includes four support assemblies, which are located at the four corners of the bottom of the frame 130. Each support assembly includes a traveling wheel 131 and a fixed support 132. The traveling wheel 131 facilitates the movement of the frame 130. After the frame 130 is moved into place, the fixed support 132 is fixed to the ground using threaded parts to fix the position of the dual-channel barcode scanner 100.

[0053] The frame 130 also includes two intermediate support legs, which are spaced apart along the second direction Y. Each intermediate support leg is located between the fixed support legs 132 of the two support leg assemblies along the first direction X. The intermediate support legs are fixed to the ground using threaded parts, which can increase the stability of the dual-channel barcode scanner 100.

[0054] This configuration allows for a simple and reliable installation of the light shield 122 over the barcode scanning component 121.

[0055] like Figure 1 and Figure 4As shown, in some embodiments of this application, the conveying mechanism 110 includes a drive assembly 111 and a tray 112. The drive assembly 111 is used to drive the tray 112 to move. The tray 112 includes a plurality of slots 113, each slot 113 being used to fix a workpiece 300.

[0056] The drive assembly 111 includes a drive motor 1111 and a transmission assembly 1112. Both the drive motor 1111 and the transmission assembly 1112 are mounted on the frame 130. The tray 112 is mounted on the actuating end of the transmission assembly 1112. The drive motor 1111 drives the tray 112 to move along the first direction X through the transmission assembly 1112. The transmission assembly 1112 can be a chain assembly or a lead screw and nut assembly.

[0057] The number of slots 113 can be two, three, five, ten, etc. Multiple slots 113 can be set at intervals along the first direction X, or they can be set along other directions.

[0058] With this configuration, the tray 112 can be moved along the first direction X, thereby driving multiple workpieces 300 through the barcode scanning module 120, and the barcode scanning component 121 can perform barcode scanning on the workpieces 300.

[0059] like Figure 1 and Figure 4 As shown, in some embodiments of this application, a plurality of slots 113 are spaced apart along the conveying direction of the conveying mechanism 110, and the barcode scanning assembly 121 includes a plurality of barcode scanners 1211, which are spaced apart along the conveying direction of the conveying mechanism 110.

[0060] Multiple slots 113 are spaced apart along a first direction X, and multiple barcode scanners 1211 are spaced apart along the first direction X. Each slot 113 and barcode scanner 1211 can correspond one-to-one, with the number of slots 113 and barcode scanners 1211 being the same. Alternatively, one barcode scanner 1211 can correspond to two adjacent slots 113. Each barcode scanner 1211 scans the workpiece 300 sequentially across two slots 113. Correspondingly, the number of slots 113 is twice the number of barcode scanners 1211.

[0061] This configuration reduces the overall external dimensions of the dual-channel barcode scanner 100 in the second direction Y, resulting in a compact device layout and a smaller installation space required.

[0062] In other embodiments, the plurality of slots 113 may also be spaced apart along other directions.

[0063] like Figure 1 and Figure 4As shown, in some embodiments of this application, the barcode scanning component 121 includes N barcode scanners 1211 spaced apart, and the tray 112 is provided with 2N slots 113 spaced apart, where N is an integer ≥1. One barcode scanner 1211 reads the information code of the workpiece 300 of two adjacent slots 113.

[0064] For example, each scanning component 121 includes five barcode scanners 1211 spaced apart along a first direction X. The tray 112 has ten slots 113 spaced apart along the first direction X. These ten slots 113 are sequentially divided into odd-numbered slots and even-numbered slots. The first barcode scanner 1211 corresponds to the first and second slots 113, the second barcode scanner 1211 corresponds to the third and fourth slots 113, and so on. Driven by the drive component 111, the tray 112 stops at a first position and a second position. When the tray 112 stops at the first position, the barcode scanner 121 reads the information codes of the workpieces 300 in the five odd-numbered slots; when the tray 112 stops at the second position, the barcode scanner 121 reads the information codes of the workpieces 300 in the five even-numbered slots. The number of barcode scanners 1211 can also be four, six, seven, etc.

[0065] This configuration allows for the scanning of twice the number of workpieces 300 using a smaller number of barcode scanners 1211, thus improving scanning efficiency.

[0066] Understandably, each pallet 112 of the conveyor mechanism 110 can receive multiple workpieces 300 in one cycle, and the scanning module 120 adopts a one-to-two method for odd and even number scanning operations, which improves scanning efficiency while reducing the number of scanners 1211. Furthermore, the drive components 111 of the two conveyor mechanisms 110 are set independently, which allows the two conveyor mechanisms 110 to work asynchronously with the upstream unloading cycle, thereby improving the scanning cycle time.

[0067] like Figure 6 and Figure 7 As shown, some embodiments of the sorting equipment 200 of this application include a dual-channel barcode scanner 100.

[0068] Due to the characteristics of the dual-channel barcode scanning device 100 in this application embodiment, the sorting equipment 200 in this application embodiment has high sorting efficiency.

[0069] like Figure 6 and Figure 7As shown, in some embodiments of this application, the sorting equipment 200 includes a sorting device 210, multiple sorting lines 220 arranged side by side, and a control device 230. The sorting device 210 is located downstream of the dual-channel barcode scanner 100, and the multiple sorting lines 220 arranged side by side are all connected to the sorting device 210. The control device 230 is used to receive the barcode scanning data from the barcode scanning module 120 and control the sorting device 210 to sort the workpieces 300 and send the workpieces 300 into the corresponding sorting lines 220.

[0070] The control device 230 is signal-connected to the two drive motors 1111, each barcode scanner 1211 of the two barcode scanning components 121, and the sorting device 210. The control device 230 controls the start and stop of the drive motors 1111, receives the barcode scanning data of the barcode scanners 1211 and performs judgment and analysis, and controls the sorting device 210 to sort the workpieces 300.

[0071] The analysis process of the scanned data by the control device 230 can classify the workpiece 300 by grade, or sort qualified and NG parts; a transfer mechanism can be set at the junction of the dual-channel scanning device 100 and the sorting device 210 to transfer the workpiece 300 from the unloading position to the feeding position of the sorting device 210, so as to realize fully automated scanning and sorting operations.

[0072] The sorting equipment 200 in this embodiment of the application uses a dual-channel barcode scanner 100. Since the dual-channel barcode scanner 100 can perform dual-channel barcode scanning operations, it improves the barcode scanning efficiency. Therefore, the sorting equipment 200 also has high sorting efficiency.

[0073] The working principle of the dual-channel barcode scanning device 100 and the sorting equipment 200 in this application embodiment is as follows:

[0074] The drive assembly 111 drives the fully loaded pallet 112 to move to the first position, and the barcode scanner 1211 scans and detects the odd-numbered workpieces 300.

[0075] The drive assembly 111 drives the tray 112 to move to the second position, and the barcode scanner 1211 scans and detects the even-numbered workpieces 300.

[0076] The control device 230 receives the scanning data from the barcode scanner 1211 and performs judgment and analysis, and the drive motor 1111 continues to move the tray 112 to the unloading position;

[0077] The sorting device 210 receives the workpieces 300 from the pallet 112, sorts the workpieces 300 according to the results of the barcode scanning data, and sends the workpieces 300 into the corresponding sorting line 220.

[0078] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0079] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
