Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to a barcode scanning device and battery manufacturing equipment. Background Technology

[0002] In the battery manufacturing process, in order to achieve traceability and management optimization throughout the product life cycle, information codes are usually engraved on the surface of the battery cells. By scanning the information codes of the battery cells with a barcode scanner, it is possible to trace not only the source of raw materials, production process parameters, quality inspection data, etc. of the battery cells, but also to achieve rapid sorting or recording, thereby improving sorting efficiency.

[0003] One common barcode scanning method involves placing the battery cell with its information code facing upwards during transport, and positioning the barcode scanner at the top of the scanning station to read the information code from the top. However, for cases where the information code is located on the front or back of the battery cell, a flipping mechanism is required to flip the battery cell so that the side with the information code is facing upwards. This not only increases the complexity of the tray but also requires a larger operating space for the flipping action, resulting in a larger layout space for the barcode scanning station. Utility Model Content

[0004] Therefore, this application proposes a barcode scanning device and battery manufacturing equipment, which can perform barcode scanning operations when the information code is set on the front or rear side of the battery cell. It has a simple structure and occupies little space.

The lifting drive is disposed on the uprights, and the scanning component is disposed on the lifting plate. The lifting drive is used to drive the lifting plate to move vertically.

[0007] Optionally, the tray includes multiple battery slots spaced apart, and the barcode scanner is movably mounted on the lifting plate along the spacing of the multiple battery slots.

[0010] Optionally, the number of the barcode scanners is N, the number of battery slots is 2N, and the barcode scanners are spaced apart along the spacing direction of the battery slots. Each barcode scanner is configured to read the information code of the battery cells of two adjacent battery slots. N is an integer and N≥1.

[0011] Optionally, the scanning device further includes: a position sensing component, disposed at the scanning station, for detecting that the tray has moved to the scanning station, and the lifting drive is configured to provide feedback and drive the scanning component to descend to the scanning height position.

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the barcode scanning device 100 of some embodiments of this application includes a conveying mechanism 110 and a scanning mechanism 120. The conveying mechanism 110 includes a conveying component and a tray 111. The tray 111 is used to carry the battery cell 200. The conveying component is used to drive the tray 111 to move so as to convey the battery cell 200 to the scanning station 130. The scanning mechanism 120 is disposed at the scanning station 130. The scanning mechanism 120 includes a frame 121, a lifting drive component 122 and a scanning component 123. The lifting drive component 122 is disposed on the frame 121. The lifting drive component 122 is used to drive the scanning component 123 to move vertically and lower to the scanning height position. The scanning port 1231 of the scanning component 123 is arranged laterally for reading the information code on the outer periphery of the battery cell 200.

[0026] The conveying mechanism 110 conveys the battery cell 200 along the first direction X, and the lifting drive 122 drives the barcode scanner 123 to move up and down along the vertical direction Z to switch between the initial position and the barcode scanning height position.

[0027] The outer periphery of the battery cell 200 refers to the front or rear side of the battery cell 200 along the first direction X, or the left or right side along the second direction Y; the first direction X and the second direction Y are two mutually perpendicular horizontal directions.

[0028] The side-mounted scanning port 1231 of the barcode scanner 123 means that the barcode port 1231 is located on the side of the barcode scanner 123 facing the barcode scanning station 130 along the horizontal direction. For example, when the tray 111 carries the battery cell 200 to the barcode scanning station 130, the barcode scanner 123 descends to the barcode scanning height position. The barcode scanner 123 is located on the rear side of the battery cell 200, and the barcode port 1231 faces the battery cell 200 along the first direction X to read the information code on the rear side of the battery cell 200.

[0029] The scanning mechanism 120 of the scanning device 100 in this application embodiment includes a lifting drive 122. The lifting drive 122 drives the scanning component 123 to descend to the scanning height position. The scanning port 1231 is arranged laterally and can read the information code on the outer periphery of the battery cell 200. This not only simplifies the structure of the conveying mechanism 110, but also allows the scanning component 123 to switch between the initial position and the scanning height position along the vertical direction Z, occupying a small installation space.

[0030] In some embodiments of this application, when the barcode scanner 123 descends to the barcode scanning height position, the barcode scanner 123 is located on the front or rear side of the pallet 111 along its conveying direction.

[0031] The conveying direction of tray 111 is the first direction X. The front side of tray 111 along the first direction X refers to the side of tray 111 closer to the discharge direction; the rear side of tray 111 along the first direction X refers to the side of tray 111 closer to the receiving direction. Taking the barcode scanner 123 located on the rear side of tray 111 as an example, the information code of battery cell 200 is located on the side closer to the discharge direction along the first direction X, i.e., the rear side. The scanning port 1231 of barcode scanner 123 faces the rear side of battery cell 200 along the first direction X to read the information code on the rear side of battery cell 200.

[0032] This configuration avoids the installation space on both sides of the conveying mechanism 110, making it easier to install other devices such as sensing components.

[0033] In other embodiments, the barcode scanner 123 may also be disposed on one side of the tray 111 along the second direction Y.

[0034] In some embodiments of this application, the frame 121 includes two uprights 1211, and the barcode scanning mechanism 120 includes a lifting plate 124. The two ends of the lifting plate 124 are slidably engaged with the two uprights 1211 through the lifting guide rail assembly 126. The lifting drive 122 is disposed on the uprights 1211, and the barcode scanning component 123 is disposed on the lifting plate 124. The lifting drive 122 is used to drive the lifting plate 124 to move vertically.

[0035] The lifting plate 124 has a first end and a second end at its two ends along the second direction Y. Two uprights 1211 are respectively arranged on both sides of the conveying mechanism 110 along the second direction Y. The first end of the lifting plate 124 is slidably engaged with the upright 1211 on the same side along the vertical direction Z through a lifting guide rail assembly 126. The second end of the lifting plate 124 is slidably engaged with the upright 1211 on the same side along the vertical direction Z through another lifting guide rail assembly 126. A lifting drive 122 is disposed on one of the uprights 1211. The actuating end of the lifting drive 122 is connected to the lifting plate 124 to drive the barcode scanner 123 to move along the vertical direction Z through the lifting plate 124.

[0036] The lifting drive component 122 is a cylinder, but it can also be other types of linear drive components.

[0037] This configuration allows the barcode scanner 123 to move smoothly and reliably along the vertical Z direction, reducing shaking and wobbling when descending to the scanning height position, thereby improving scanning accuracy.

[0038] In some embodiments of this application, the tray 111 includes a plurality of battery slots 1111, which are spaced apart, and the barcode scanner 123 is movably disposed on the lifting plate 124 along the spacing direction of the plurality of battery slots 1111.

[0039] Multiple battery slots 1111 are spaced apart along the second direction Y, and each battery slot 1111 is used to accommodate a battery cell 200. A barcode scanner 123 is movably disposed on the lifting plate 124 along the second direction Y to switch between the multiple battery slots 1111 and read the information codes of the multiple adjacent battery cells 200 one by one.

[0040] With this configuration, one barcode scanner 123 can read the information codes of multiple battery cells 200. On the one hand, it can accommodate the arrangement spacing of the battery slots 1111 in the second direction Y. On the other hand, it can reduce the number of barcode scanners 123 and reduce the manufacturing cost of the barcode scanner 100.

[0041] In other embodiments, the battery slot 1111 and the barcode scanner 123 can also be configured in a one-to-one correspondence.

[0042] In some embodiments of this application, the scanning mechanism 120 includes a transverse drive and a transverse plate 125. The transverse drive is disposed on the lifting plate 124, and the scanning component 123 is disposed on the transverse plate 125. The transverse drive is used to drive the transverse plate 125 to move along the spaced arrangement direction of the plurality of battery slots 1111.

[0043] The lateral drive unit is used to drive the lateral plate 125 to move along the second direction Y, so as to move to each battery slot 1111 corresponding to the scanning unit 123. For example, in an implementation where odd-numbered battery slots 1111 are scanned first and then even-numbered battery slots 1111 are scanned, the lateral drive unit drives the lateral plate 125 to switch between a first position and a second position along the second direction Y. When the lateral plate 125 is in the first position, the scanning unit 123 scans the odd-numbered battery slots 1111; when the lateral plate 125 is in the second position, the scanning unit 123 scans the even-numbered battery slots 1111. The lateral drive unit can be a cylinder or other types of linear drive units.

[0044] With this configuration, the barcode scanner 123 can be moved along the second direction Y to read the information codes of the battery cells 200 in multiple battery slots 1111 one by one in a simple and reliable manner.

[0045] In some embodiments of this application, the transverse plate 125 and the lifting plate 124 are slidably engaged by the transverse guide rail assembly 127.

[0046] Specifically, the transverse plate 125 and the lifting plate 124 are slidably engaged along the second direction Y via the transverse guide rail assembly 127.

[0047] This configuration allows the barcode scanner 123 to move smoothly and reliably along the second direction Y, reducing jitter and shaking during switching between different battery slots 1111, thereby improving scanning accuracy.

[0048] In some embodiments of this application, the number of barcode scanners 123 is N, the number of battery slots 1111 is 2N, the multiple barcode scanners 123 are spaced apart along the spacing direction of the multiple battery slots 1111, and each barcode scanner 123 is configured to read the information code of the battery cell 200 of two adjacent battery slots 1111, where N is an integer and N≥1.

[0049] Multiple barcode scanners 123 are spaced apart along the second direction Y, and multiple battery slots 1111 are spaced apart along the second direction Y. When the transverse plate 125 is in the first position, the barcode scanners 123 read the information codes of the battery cells 200 in the odd-numbered battery slots 1111; when the transverse plate 125 is in the second position, the barcode scanners 123 read the information codes of the battery cells 200 in the even-numbered battery slots 1111.

[0050] For example, if N=2, there are two barcode scanners 123 and four battery slots 1111; if N=1, there is one barcode scanner 123 and two battery slots 1111; if N=3, there are three barcode scanners 123 and six battery slots 1111, and so on.

[0051] This setup reduces the number of items to be scanned (123) while maintaining scanning efficiency, ensuring that the cycle time of the scanning station (130) matches the production line.

[0052] In some embodiments of this application, the scanning device 100 further includes a position sensing component 140, which is disposed at the scanning station 130 and is used to detect that the tray 111 moves to the scanning station 130. The lifting drive component 122 is configured to provide feedback and drive the scanning component 123 to descend to the scanning height position.

[0053] The position sensing assembly 140 can be a set of through-beam sensors, with the receiving end and the transmitting end arranged on both sides of the conveying mechanism 110 along the second direction Y; the position sensing assembly 140 can also include a detection element and a proximity sensor, with the detection element arranged on the tray 111 and the proximity sensor arranged on one side of the conveying mechanism 110 along the second direction Y.

[0054] This configuration allows the barcode scanner 123 to automatically descend to the barcode scanning height to read the information code of the battery cell 200.

[0055] In some embodiments of this application, the barcode scanning device 100 further includes a reset sensing component 150, which is used to detect that the tray 111 leaves the barcode scanning station 130, and the lifting drive component 122 is configured to provide feedback and drive the barcode scanning component 123 to reset.

[0056] The reset sensing assembly 150 is disposed downstream of the position sensing assembly 140 along the second direction Y. The reset sensing assembly 150 can be a set of through-beam sensors, with the receiving end and the transmitting end disposed on both sides of the conveying mechanism 110 along the second direction Y. The reset sensing assembly 150 can also include a detection element and a proximity sensor, with the detection element disposed on the tray 111 and the proximity sensor disposed on one side of the conveying mechanism 110 along the second direction Y.

[0057] The barcode scanning device 100 also includes a control device, which is electrically connected to the lifting drive 122, the lateral drive, the barcode scanning device 123, the position sensing component 140, and the reset sensing component 150.

[0058] This setup allows the barcode scanner 123 to automatically reset to its initial position, ready for the next scanning cycle.

[0059] Some embodiments of the battery manufacturing equipment in this application include a barcode scanning device 100.

[0060] Due to the aforementioned characteristics of the barcode scanning device 100 in this application embodiment, the battery manufacturing equipment in this application embodiment can transmit the information code set on the outer periphery of the battery cell 200 and perform barcode scanning detection. It has a simple structure and occupies a small installation space.

[0061] like Figures 1 to 3 As shown, the working principle of the barcode scanning device 100 in this embodiment is as follows:

[0062] The pallet 111 of the conveying mechanism 110 conveys battery cells 200 along the first direction X. Each pallet 111 is provided with four battery slots 1111, each battery slot 1111 accommodating one battery cell 200. The four battery cells 200 are spaced apart along the second direction Y. Each battery cell 200 has an information code on its rear side along the first direction X.

[0063] When the tray 111 arrives at the barcode scanning station 130, the lifting drive 122 drives the lifting plate 124 to descend vertically in the Z direction to the barcode scanning height position. The horizontal moving plate 125 drives the two barcode scanning components 123 to scan at the first position and the second position respectively, thus completing the reading of the information codes of the odd-numbered battery cells 200 and the even-numbered battery cells 200.

[0064] The conveying mechanism 110 drives the battery cell 200 to discharge along the first direction X. The transverse drive drives the transverse plate 125 to reset. The lifting drive 122 drives the lifting plate 124 to rise along the vertical direction Z. The barcode scanner 123 returns to the initial position, completing one cycle of barcode scanning.

[0065] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0066] 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.
