However, the production line of cylindrical batteries is accelerating towards high speed, and the traditional on-line code scanning can no longer meet the beat requirements. Since the battery two-dimensional code is on the surface of the cylinder or the cup, the direction of the two-dimensional code is not unique when flowing on the production line. The prior art usually uses the method of manually rotating the battery by hand to adjust the orientation of the two-dimensional code for code scanning, or uses a servo motor to drive the clamping jaw to clamp the battery and rotate it for code scanning. The former has low efficiency, and the latter has high equipment cost and inconvenient maintenance, and both are difficult to meet the requirements of high-speed code scanning.

[0038] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0039] The following specifically describes the code scanning device 100 according to an embodiment of the present utility model in conjunction with the accompanying drawings.

[0040] As Figures 1 to 4 shown, the code scanning device 100 according to an embodiment of the present utility model includes: a first conveying mechanism 10, a second conveying mechanism 20, a turntable 30, and a code scanning mechanism 40.

[0041] Specifically, the code scanning device 100 has a code scanning station 101. The first conveying mechanism 10 and the second conveying mechanism 20 respectively convey the carrier 200 along a first direction, and the code scanning station 101 is located between the first conveying mechanism 10 and the second conveying mechanism 20. The turntable 30 is rotatably disposed at the code scanning station 101 around its own axis, and a plurality of accommodating portions 31 adapted to accommodate the carrier 200 are circumferentially spaced apart on the turntable 30. The accommodating portions 31 are used to receive the carrier 200 from the first conveying mechanism 10 and convey the carrier 200 along an arc path to the second conveying mechanism 20. The code scanning mechanism 40 is disposed at the code scanning station 101, and the code scanning mechanism 40 includes a plurality of code scanning guns 42 arranged in a ring to scan the carrier 200 or the battery 300 in the carrier 200.

[0042] In other words, the code scanning device 100 according to an embodiment of the present utility model is mainly composed of a first conveying mechanism 10, a second conveying mechanism 20, a turntable 30, and a code scanning mechanism 40.

[0043] Among them, the first conveying mechanism 10 and the second conveying mechanism 20 can be arranged at intervals, and the code scanning station 101 can be arranged between the first conveying mechanism 10 and the second conveying mechanism 20. Both the first conveying mechanism 10 and the second conveying mechanism 20 can convey the carrier 200 along the first direction. That is to say, the first conveying mechanism 10 and the second conveying mechanism 20 can convey the carrier 200 in the same direction. The carrier 200 can accommodate the battery 300.

[0044] Optionally, the carrier 200 can include a cup, the battery 300 can be a cylindrical battery 300, and the bottom of the cylindrical battery 300 can be accommodated in the cup. The first conveying mechanism 10 and the second conveying mechanism 20 can have the same structure. For example, both the first conveying mechanism 10 and the second conveying mechanism 20 are conveyor belts.

[0045] The code scanning station 101 can be provided with a turntable 30 and a code scanning mechanism 40. The turntable 30 can rotate around its own axis, and the axis of the turntable 30 can extend in the vertical direction. A plurality of accommodating parts 31 can be provided on the circumference of the turntable 30, and the shape and size of the accommodating parts 31 can be adapted to the shape and size of the carrier 200. For example, when the carrier 200 is a circular cup, the accommodating part 31 can have an arc surface that can fit with the circular cup.

[0046] During the rotation of the turntable 30, the carrier 200 accommodated in the accommodating part 31 can rotate a predetermined angle around the axis of the turntable 30, so that the carrier 200 moves along an arc path. One end of the arc path can be connected to the first conveying mechanism 10, and the other end of the arc path can be connected to the second conveying mechanism 20.

[0047] In addition, the code scanning mechanism 40 can scan the carrier 200 accommodated in the accommodating part 31 or the battery 300 in the carrier 200. Specifically, a two-dimensional code can be provided on the carrier 200 or the battery 300. During the process of being conveyed on the first conveying mechanism 10, the second conveying mechanism 20 and the turntable 30, the direction of the two-dimensional code on the carrier 200 is not unique. A plurality of code scanning guns 42 can be arranged at the code scanning station 101 to cover the cylindrical surface of the carrier 200 or the battery 300, so that no matter what direction the two-dimensional code on the carrier 200 or the battery 300 faces, at least one code scanning gun 42 can scan the two-dimensional code, ensuring the reliability of high-speed code scanning.

[0048] The working process of the code scanning device 100 of the present utility model will be described in detail below.

[0049] The first conveying mechanism 10 conveys the carrier 200 to the turntable 30 along the first direction. The receiving portion 31 on the turntable 30 receives the carrier 200 and conveys the carrier 200 along an arc path. When the carrier 200 is conveyed on the turntable 30, since it is conveyed along an arc path, the distance between adjacent carriers 200 can be increased. When the carrier 200 is conveyed by the turntable 30 to a predetermined position, the turntable 30 can stop rotating. At this time, there is enough space between two adjacent carriers 200, and the code scanning mechanism 40 can accurately scan the current carrier 200 or the battery 300 in the carrier 200 without being affected by the remaining carriers 200. After the code scanning is completed, the turntable 30 continues to rotate and conveys the carrier 200 to the second conveying mechanism 20, and the second conveying mechanism 20 continues to convey the carrier 200 downstream along the first direction.

[0050] Thus, for the code scanning device 100 according to the embodiment of the present invention, conveying mechanisms capable of conveying the carrier 200 along the same direction are respectively arranged before and after the code scanning station 101. By using the turntable 30 to convey the carrier 200 along an arc path, the distance between adjacent carriers 200 can be increased. Cooperating with multiple code scanning guns 42 arranged at the code scanning station 101, the code scanning mechanism 40 can accurately and efficiently scan the carrier 200 on the turntable 30 or the battery 300 in the carrier 200, realizing high-speed, continuous and stable on-line code scanning. The carrier 200 does not need to be separated from the conveying line, and there will be no missed scanning situation, which is beneficial to the high-speed development of the battery 300 production line.

[0051] According to an embodiment of the present invention, the first conveying mechanism 10 conveys the carrier 200 along a first straight path, the second conveying mechanism 20 conveys the carrier 200 along a second straight path, the extension line of the first straight path coincides with the second straight path, and the arc path is connected between the first straight path and the second straight path.

[0052] Specifically, the first conveying mechanism 10 may include a first conveyor belt extending along the first direction, the second conveying mechanism 20 may include a second conveyor belt extending along the first direction, the first conveyor belt and the second conveyor belt respectively convey the carrier 200 along a straight path, the path of the carrier 200 on the first conveyor belt is the first straight path, and the path of the carrier 200 on the second conveyor belt is the second straight path.

[0053] It should be noted that the first straight path may be the connection line between the positions passed by the center point of the carrier 200 during the process of the carrier 200 being conveyed along the first direction on the first conveying mechanism 10, and the second straight path may be the connection line between the positions passed by the center point of the carrier 200 during the process of the carrier 200 being conveyed along the first direction on the second conveying mechanism 20. The arc path may be the connection line between the positions passed by the center point of the carrier 200 during the process of the carrier 200 being conveyed on the turntable 30.

[0054] The first straight path and the second straight path can be located on the same straight line, and the arc path is connected between the first straight path and the second straight path. That is to say, the carrier 200 is conveyed along the same straight line before and after passing through the turntable 30. The scanning process will not change the conveying direction of the carrier 200, which is more conducive to the high-speed conveying of the carrier 200, avoiding the overturning of the carrier 200 during the conveying process, and improving the reliability and stability of the scanning device 100.

[0055] According to some other embodiments of the present invention, the shortest distance between the center point of the turntable 30 and the extension line of the first straight path is L, the radius of the turntable 30 is R, and L < R.

[0056] Specifically, as Figure 1 shown, most of the structure of the turntable 30 can be arranged on the left side of the first conveying mechanism 10, and a small part of the turntable 30 can protrude to the right and extend to the right side of the first conveying mechanism 10. The center point of the turntable 30 is located on the left side of the first conveying mechanism 10. The arc path can be a minor arc protruding towards the right side of the first conveying mechanism 10, and the extension line of the first straight path can be located on the left side of the arc path. Therefore, L < R.

[0057] Thus, it can make the arc path and the first straight path and the arc path and the second straight path smoothly transition through an obtuse angle, which can not only achieve the purpose of increasing the distance between the carriers 200, but also reduce the path length passed by the carriers 200, and at the same time prevent the carriers 200 from overturning, which is beneficial to realizing high-speed scanning.

[0058] In some specific embodiments of the present invention, the scanning device 100 further includes a guiding mechanism 50. The guiding mechanism 50 is arranged at the scanning station 101. The guiding mechanism 50 is provided with a guiding groove 51. At least a part of the guiding groove 51 extends along the arc path to guide the carrier 200 to move along the arc path. One end of the guiding groove 51 is communicated with the first conveying mechanism 10, and the other end of the guiding groove 51 is communicated with the second conveying mechanism 20.

[0059] Specifically, the scanning station 101 can also be provided with a guiding mechanism 50. The guiding mechanism 50 can have a guiding groove 51. In the first direction, both ends of the guiding groove 51 can be open. One end of the guiding groove 51 can be communicated with the first conveying mechanism 10, and the other end of the guiding groove 51 can be communicated with the second conveying mechanism 20.

[0060] As Figure 1As shown, the guide groove 51 may include a first section 511, a second section 512, and a third section 513 sequentially connected along a first direction, wherein the first section 511 and the third section 513 may be straight sections, and the second section 512 may be an arcuate groove extending along an arcuate path. A portion of the turntable 30 may extend into the guide mechanism 50 and enter the second section 512 of the guide groove 51, whereby when the turntable 30 drives the carrier 200 to rotate, the arcuate groove may guide and limit the movement of the carrier 200 to prevent the carrier 200 from tipping over.

[0061] In addition, the first section 511 and the third section 513 can be on the same straight line as the first straight path. The carrier 200 output by the first conveying mechanism 10 can first enter the first section 511, move a certain distance in the straight direction in the first section 511, and then enter the arc-shaped second section 512. At this time, the carrier 200 can enter the accommodating portion 31 of the turntable 30, and move in an arc along the second section 512 under the drive of the turntable 30, and finally leave the turntable 30 and enter the third section 513, and enter the second conveying mechanism 20 in sequence through the third section 513.

[0062] In this embodiment, a guide mechanism 50 is provided at the code scanning station 101 to guide the movement path of the carrier 200, which can assist the turntable 30 in pulling the adjacent carriers 200 apart, and can also limit the carrier 200 to prevent the carrier 200 from tipping over during transportation.

[0063] According to some optional embodiments of the present invention, the outer circumferential surface of the turntable 30 includes a plurality of arc surfaces 32 and a plurality of inclined surfaces 33 arranged alternately along the circumference of the turntable 30, the arc surfaces 32 are recessed toward the center of the turntable 30 to form a receiving portion 31, the inclined surfaces 33 extend outward at an angle, and one end of the inclined surface 33 close to the center of the turntable 30 is tangent to the adjacent arc surface 32.

[0064] Specifically, the outer circumferential surface of the turntable 30 may be mainly composed of multiple arc surfaces 32 and multiple inclined surfaces 33, which are arranged in a staggered manner, that is, an inclined surface 33 is connected between two adjacent arc surfaces 32, and an arc surface 32 is connected between adjacent inclined surfaces 33.

[0065] The arc surface 32 may be formed as the accommodating portion 31 . When the turntable 30 transports the carrier 200 , the arc surface 32 may fit the outer peripheral surface of the carrier 200 and apply a driving force to the carrier 200 .

[0066] The inclined surface 33 can extend obliquely relative to the center of the turntable 30. The end of the inclined surface 33 close to the center of the turntable 30 is connected to an arc surface 32, and the end of the inclined surface 33 away from the center of the turntable 30 can be connected to another arc surface 32. The connection here can include direct connection and indirect connection.

[0067] For ease of description, the arc surface 32 at one end of the inclined surface 33 close to the center of the turntable 30 can be defined as the first arc surface, and the arc surface 32 at the end of the inclined surface 33 far from the center of the turntable 30 can be defined as the second arc surface. As Figure 2 shown, from the top-down perspective, the projection of the inclined surface 33 on the horizontal plane is tangent to the projection of the adjacent first arc surface on the horizontal plane.

[0068] By providing the inclined surface 33 between adjacent arc surfaces 32, the distance between adjacent arc surfaces 32 can be increased, thereby increasing the distance between adjacent carriers 200. At the same time, the inclined surface 33 does not interfere with the linear and arc motions of the carrier 200, facilitating the code scanning by the code scanning mechanism 40 and preventing adjacent carriers 200 from interfering with the code scanning.

[0069] According to some other embodiments of the present invention, the end of the inclined surface 33 far from the center of the turntable 30 is smoothly transitioned with the adjacent arc surface 32. As Figure 2 shown, a fillet 34 can be provided between the inclined surface 33 and the adjacent second arc surface to prevent the turntable 30 from having sharp edges that may scratch the carrier 200 or the battery 300.

[0070] In some specific embodiments of the present invention, a code scanning point 102 is provided on the arc path, and the code scanning mechanism 40 includes an adjustment bracket 41. The adjustment bracket 41 is provided at the code scanning station 101. A plurality of code scanning guns 42 are circumferentially spaced apart on the adjustment bracket 41 and are directed towards the code scanning point 102 to scan the carrier 200 or the battery 300 within the carrier 200 at the code scanning point 102.

[0071] Specifically, the adjustment bracket 41 can be fixedly provided at the code scanning station 101. At least two code scanning guns 42 can be connected to the adjustment bracket 41, and the plurality of code scanning guns 42 can be arranged around the code scanning point 102 on the arc path. Preferably, the code scanning point 102 can be located at the center point of the arc path.

[0072] In addition, the adjustment bracket 41 can adjust the position and orientation of the code scanning gun 42 to meet the code scanning requirements of carriers 200 and batteries 300 with different heights and diameters, improving the applicability of the code scanning device 100.

[0073] According to some alternative embodiments of the present invention, the number of code scanning guns 42 ≥ 4. By providing four or more code scanning guns 42, the scanning range of each code scanning gun 42 can be ≥ 90°. Thus, it can better ensure that the fields of view of these code scanning guns 42 completely cover the entire cylindrical surface of the carrier 200 or the battery 300, enabling the code scanning and reading of the two-dimensional code at any position.

[0074] For example, as Figure 3As shown, four barcode scanners 42 can be provided on the adjustment bracket 41. The four barcode scanners 42 can be symmetrically distributed about the center. The included angle between the connecting lines of two adjacent barcode scanners 42 and the scanning point 102 can be 90°.

[0075] According to some other embodiments of the present invention, multiple barcode scanners 42 are evenly spaced along the circumferential direction. Thus, the effective field of view of each barcode scanner 42 can be increased, and the overlapping area of the fields of view between adjacent barcode scanners 42 can be reduced, which is beneficial to the full coverage of the cylindrical surface of the vehicle 200 or the battery 300.

[0076] In some specific embodiments of the present invention, the adjustment bracket 41 includes a plurality of rods 411 and a connecting block 413. The plurality of rods 411 are sequentially connected by locking members 412. Two adjacent rods 411 are perpendicular to each other. Each rod 411 is movable relative to the locking member 412 connected to itself along its own extension direction, and each rod 411 is rotatable relative to the locking member 412 connected to itself about its own axis. The foremost one of the plurality of rods 411 is provided at the scanning station. The connecting block 413 is provided on the rearmost one of the plurality of rods 411, and the barcode scanner 42 is connected to the connecting block 413.

[0077] Specifically, the adjustment bracket 41 can include three rods 411. For the convenience of description, the three rods 411 can be defined as the first rod 4111, the second rod 4112, and the third rod 4113. The first rod 4111 can extend in the vertical direction and can be fixedly provided at the scanning station 101. The first rod 4111 and the second rod 4112 can be connected by a locking member 412. The first rod 4111 can move relative to the locking member 412 in the vertical direction, and the first rod 4111 can rotate relative to the locking member 412 about the axis extending vertically, so that the height and angle of the second rod 4112 can be adjusted.

[0078] The second rod 4112 can extend in the horizontal direction. Two locking members 412 can be provided on the second rod 4112. One of the locking members 412 is used to connect the first rod 4111, and the other locking member 412 is used to connect the second rod 4112. The second rod 4112 can move relative to the two locking members 412 along its own extension direction, and the second rod 4112 can rotate relative to its own axis relative to the two locking members 412.

[0079] The third rod 4113 can extend in the vertical direction and can move in the vertical direction or rotate about the axis extending vertically relative to the locking member 412 between the second rod 4112 and the third rod 4113. A connecting block 413 can be connected to the bottom of the third rod 4113. The connecting block 413 can be in the shape of a cuboid, and four barcode scanners 42 can be installed on the four circumferential side surfaces of the connecting block 413.

[0080] The locking member 412 can lock or unlock the rod member 411. In the unlocked state, the rod member 411 can move or rotate relative to the locking member 412. In the locked state, the relative positions of the locking member 412 and the rod member 411 are locked. By unlocking the locking member 412, the position of the rod member 411 can be adjusted, thereby changing the position of the connecting block 413 and the barcode scanner 42 on the connecting block 413, and realizing the adjustment of the position of the barcode scanner 42 in the horizontal plane, the height in the vertical direction, and the rotation angle around the vertical axis.

[0081] In summary, for the barcode scanning device 100 according to the embodiment of the present invention, conveying mechanisms capable of conveying the carrier 200 along the same direction are respectively arranged in front of and behind the barcode scanning station 101. By using the turntable 30 to convey the carrier 200 along an arc path, the distance between adjacent carriers 200 can be increased. Cooperating with multiple barcode scanners 42 arranged at the barcode scanning station 101, the barcode scanning mechanism 40 can accurately and efficiently scan the carrier 200 on the turntable 30 or the battery 300 in the carrier 200, realizing high-speed, continuous and stable on-line barcode scanning. The carrier 200 does not need to be separated from the conveying line, and there will be no missed scanning situation, which is beneficial to the high-speed development of the battery 300 production line.
