[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] The code reading mechanism 100 according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 5 As shown, the code reading mechanism 100 according to the embodiment of the utility model includes at least one sub-mechanism 1, and each sub-mechanism 1 includes: a turntable 10, a plurality of first bearing assemblies 20, a code reading assembly 30 and a cam assembly 40.

[0039] Specifically, each sub-mechanism 1 has a standby station a and a code reading station b. The turntable 10 is rotatable around its own axis. The turntable 10 has a plurality of first mounting portions 11 arranged along its own circumference. In the axial direction of the turntable 10, the standby station a and the code reading station b are spaced apart. Each first bearing assembly 20 is movably arranged on the first mounting portion 11 between the standby station a and the code reading station b. The first bearing assembly 20 is used to carry the code piece to be read. The code reading assembly 30 is arranged at the standby station a and is used to read the code piece to be read. The cam assembly 40 is connected to the plurality of first bearing assemblies 20 and is used to guide each first bearing assembly 20 to move between the standby station a and the code reading station b.

[0040] In other words, the code reading mechanism 100 according to the embodiment of the utility model is mainly composed of one or more sub-mechanisms 1. The code reading mechanism 100 can perform RFID code reading on the code-to-be-read part. Optionally, the code-to-be-read part can be a support cup 200 with a chip, and the support cup 200 carries and binds the battery cell 300. The code reading mechanism 100 can perform RFID code reading on the support cup 200, thereby tracing the information of the battery cell 300. The battery cell 300 may include but is not limited to a cylindrical battery cell 300. It should be noted that during the code reading process, each support cup 200 contains a battery cell 300. Figures 1 to 3 Some of the battery cells 300 are not shown.

[0041] The number of sub-mechanisms 1 in the code reading mechanism 100 can be one or more, which is not limited here. Each sub-mechanism 1 can have a standby station a and a code reading station b.

[0042] Each sub-mechanism 1 is mainly composed of a rotating disk 10, a plurality of first bearing components 20, a code reading component 30 and a cam component 40. The rotating disk 10 can be connected to a driving structure and rotate around its own axis under the drive of the driving structure.

[0043] The turntable 10 may be provided with a plurality of first mounting portions 11, which may be arranged along the circumference of the turntable 10, and each first mounting portion 11 may be provided with a first bearing assembly 20, and the first bearing assembly 20 is movably connected to the first mounting portion 11. Each first bearing assembly 20 may be used to carry a support cup 200, and each support cup 200 may contain a battery cell 300.

[0044] In the axial direction of the turntable 10, the standby station a and the code reading station b can be spaced apart, and the code reading station b and the standby station a can be arranged along the circumference of the turntable 10. The first bearing assembly 20 can move between the standby station a and the code reading station b, and the code reading station b can be provided with a code reading assembly 30, which can read the code of the cup 200 carried by the first bearing assembly 20 at the code reading station b.

[0045] It should be noted that the number of the code reading components 30 can be one or more, which is not limited here. Providing multiple code reading components 30 can read multiple code pieces to be read at the same time, which is conducive to improving the code reading efficiency. Figure 1 As shown, two code reading assemblies 30 may be provided on the circumference of the turntable 10 , and the two code reading assemblies 30 are arranged along the circumference of the turntable 10 .

[0046] In addition, the first bearing assembly 20 can be connected to the cam assembly 40. During the rotation of the turntable 10, the turntable 10 can make the first bearing assembly 20 rotate around the axis of the turntable 10. At the same time, the cam assembly 40 cooperates with the first bearing assembly 20 to guide the first bearing assembly 20 to move between the standby station a and the code reading station b. Since the standby station a and the code reading station b are spaced apart in the axial direction of the turntable 10, the first bearing assembly 20 can also be displaced in the axial direction of the turntable 10 when following the rotation of the turntable 10, so that the first bearing assembly 20 at the code reading station b and the first bearing assembly 20 at the standby station a are misaligned in the axial direction of the turntable 10, so as to avoid interference between adjacent code pieces to be read and affect code reading.

[0047] The code reading process of the code reading mechanism 100 of this embodiment is described in detail below.

[0048] The axis of the turntable 10 can be placed vertically, and the code reading station b can be lower than the standby station a. The turntable 10 is rotated so that the cups 200 equipped with the battery cells 300 are sequentially loaded onto the multiple first supporting components 20. When just loaded, the cups 200 can be in the standby station a. As the turntable 10 rotates, when the cup 200 moves to the code reading station b, the cup 200 is misaligned in height with the other cups 200, and the code reading component 30 reads the code of the cup 200, while the other cups 200 are still in the standby station a. After the current cup 200 completes the code reading, it can move from the code reading station b to the standby station a, and at the same time, the next cup 200 moves from the standby station a to the code reading station b for code reading.

[0049] Therefore, according to the code reading mechanism 100 of the embodiment of the utility model, a movable first bearing assembly 20 is arranged on the turntable 10 for bearing the code pieces to be read, so that the first bearing assembly 20 rotates together with the follower turntable 10, and at the same time, the cam assembly 40 is used to guide the first bearing assembly 20 to move between the standby station a and the code reading station b, so that the adjacent code pieces to be read on the turntable 10 can be axially misaligned during code reading, and the distance between adjacent code pieces to be read is increased to avoid mutual interference between adjacent code pieces to be read, so that the code reading assembly 30 can read codes normally. Compared with the prior art, the code reading mechanism 100 of this embodiment no longer requires an alignment mechanism to read codes normally, which simplifies the structure of the code reading mechanism 100 and reduces the cost of the code reading mechanism 100.

[0050] According to one embodiment of the utility model, adjacent first mounting portions 11 are spaced apart by a preset distance in the circumferential direction of the turntable 10, so that adjacent first bearing assemblies 20 and the code pieces to be read carried thereon can be spaced apart by a preset distance in the circumferential direction of the turntable 10, which is beneficial to increasing the distance between the code piece to be read at the code reading station b and the adjacent code piece to be read at the standby station a, better preventing interference between the two, and beneficial to improving the reliability of the code reading mechanism 100.

[0051] According to some other embodiments of the utility model, the cam assembly 40 includes a mounting member 41 and a plurality of cam followers 42. The mounting member 41 is provided with an annular cam groove 411, and the turntable 10 is rotatable relative to the mounting member 41. Each first bearing assembly 20 is rotatably connected with a cam follower 42, and each cam follower 42 is provided in the cam groove 411 and can move along the cam groove 411 to guide the first bearing assembly 20 to move between the standby station a and the code reading station b.

[0052] In other words, the cam assembly 40 is mainly composed of a mounting member 41 and a plurality of cam followers 42. Figure 3 As shown, the mounting member 41 may be annular, and the rotating disk 10 may be coaxially arranged with the mounting member 41. An inwardly recessed cam groove 411 may be provided on the outer circumference of the mounting member 41, and the cam groove 411 may be annular. The mounting member 41 may be fixedly arranged, and the rotating disk 10 may rotate relative to the mounting member 41. When the rotating disk 10 drives the first bearing assembly 20 to rotate, the mounting member 41 may remain stationary.

[0053] Each first bearing assembly 20 may be provided with a cam follower 42, which may match the cam groove 411. Each cam follower 42 may extend into the cam groove 411, and as the turntable 10 rotates, the cam follower 42 may move along the cam groove 411. By designing the shape of the cam groove 411, the movement trajectory of the cam follower 42 may be controlled, thereby guiding the first bearing assembly 20 to move between the standby station a and the code reading station b.

[0054] In this embodiment, the structure of the cam groove 411 and the cam follower 42 can utilize the rotation of the turntable 10 to enable the first supporting component 20 to realize reciprocating motion between the standby station a and the code reading station b, thereby cooperating with the code reading component 30 to continuously read the code, and has the advantages of stable movement mode, small friction loss, low energy consumption and long service life.

[0055] In some specific embodiments of the present invention, the cam groove 411 includes a standby section 411a, a code reading section 411b and two transition sections 411c. The standby section 411a and the code reading section 411b are spaced apart in the circumferential direction and the axial direction of the turntable 10, and the transition section 411c is connected between the adjacent ends of the standby section 411a and the code reading section 411b. When the cam follower 42 on the first bearing assembly 20 is in the standby section 411a, the first bearing assembly 20 is in the standby position a. When the cam follower 42 on the first bearing assembly 20 is in the code reading section 411b, the first bearing assembly 20 is in the code reading position b.

[0056] Specifically, the cam groove 411 can be formed by connecting four grooves, which are a standby segment 411a, a code reading segment 411b and two transition segments 411c. For ease of explanation, the two transition segments 411c can be defined as a first transition segment 411c and a second transition segment 411c. In the circumferential direction of the rotating disk 10, the standby segment 411a, the first transition segment 411c, the code reading segment 411b and the second transition segment 411c are connected in sequence to form an annular groove structure. Therefore, the standby segment 411a and the code reading segment 411b are spaced apart in the axial direction of the rotating disk 10.

[0057] In addition, in the axial direction of the turntable 10, the standby section 411a and the code reading section 411b can be spaced apart, the standby section 411a can correspond to the standby station a, and the code reading section 411b can correspond to the code reading station b. Figure 3 As shown, the standby section 411a and the code reading section 411b may be staggered in the height direction, so that the first supporting assembly 20 in the standby section 411a and the first supporting assembly 20 in the code reading section 411b are staggered in the height direction.

[0058] When the cam follower 42 on the first bearing assembly 20 is in the standby section 411a, the first bearing assembly 20 can be in the standby position a, and when the cam follower 42 on the first bearing assembly 20 is in the code reading section 411b, the first bearing assembly 20 can be in the code reading position b. The code reading assembly 30 can be arranged close to the code reading section 411b.

[0059] Optionally, each transition section 411 c may be a smooth arc-shaped groove, so that the moving trajectory of the cam follower 42 is smoother.

[0060] In this embodiment, by designing the structure of the cam groove 411 and dividing it into a standby section 411a, a code reading section 411b and two transition sections 411c, the first supporting component 20 can be guided to realize reciprocating motion between the standby station a and the code reading station b, thereby cooperating with the code reading component 30 to continuously read the code, having good stability and reliability, and facilitating precise control during the code reading process.

[0061] According to some optional embodiments of the present invention, each first bearing assembly 20 includes a positioning block 21, which is movably disposed on the first mounting portion 11 between the standby station a and the code reading station b, and has a positioning groove 211 for positioning the code piece to be read.

[0062] Specifically, the first mounting portion 11 can be connected to the positioning block 21, and the positioning block 21 can also move in the axial direction of the rotating disk 10 when the rotating disk 10 rotates. It should be noted that the above connection may include but is not limited to direct connection and indirect connection. The cam follower 42 can be connected to the positioning block 21, and the connection may include but is not limited to direct connection and indirect connection.

[0063] The positioning block 21 may have a positioning groove 211, and the positioning groove 211 may be used to position the code-reading component. Figure 4 and Figure 5 As shown, the support cup 200 can be positioned and fixed in the positioning groove 211 .

[0064] In this embodiment, the positioning block 21 is provided to position the code piece to be read, which can ensure the position accuracy of the code piece to be read during code reading, thereby improving the reliability of the code reading mechanism 100. At the same time, the positioning block 21 can also be used to fix the code piece to be read to prevent the code piece from moving during the code reading process.

[0065] According to some other embodiments of the utility model, each first mounting portion 11 is provided with a guide member 111, and each first bearing assembly 20 also includes a guide fitting member 22, which is connected between the positioning block 21 and the cam follower 42, and the guide member 111 is connected to the guide fitting member 22 and guides the guide fitting member 22 to move along the axial direction of the turntable 10.

[0066] Specifically, the positioning block 21 and the first mounting portion 11 may be connected via a guide member 111 and a guide fitting member 22. The guide member 111 may be fixedly mounted on the first mounting portion 11, for example, the guide member 111 may be fixedly mounted on the outer circumferential surface of the turntable 10. The guide fitting member 22 may be fixedly connected to the positioning block 21, the guide fitting member 22 may be connected to the guide member 111, the guide member 111 may guide the guide member 111 to move along the axial direction of the turntable 10, and the cam follower 42 may be connected to the guide fitting member 22, so that as the turntable 10 rotates, when the cam follower 42 passes through the transition section 411c, the positioning block 21 may move along the axial direction of the turntable 10 under the guidance of the guide member 111.

[0067] In this embodiment, the guide member 111 cooperates with the guide matching member 22 to achieve smooth and precise movement of the positioning block 21 and the code to be read. In conjunction with the cam assembly 40, the first supporting assembly 20 can be accurately driven to switch between the standby station a and the code reading station b.

[0068] In some specific embodiments of the present invention, the guide member 111 is a guide rail, which extends along the axial direction of the turntable 10 , and the guide matching member 22 is a slider.

[0069] Specifically, the guide rail can be fixed on the outer circumference of the turntable 10, and when the turntable 10 is placed vertically, the guide rail can extend in the vertical direction. The slider can be connected to the guide rail and can slide along the guide rail. The combination of the slider and the guide rail has the advantages of simple structure and low friction resistance, which is conducive to the smooth and accurate movement of the positioning block 21.

[0070] In some specific embodiments, the slider can be set on the side of the guide rail away from the center of the turntable 10, the positioning block 21 can be set on the side of the slider away from the guide rail, a connecting piece 23 can be provided between the slider and the cam follower 42, and the cam follower 42 can be set on the side of the guide rail toward the center of the turntable 10.

[0071] According to some optional embodiments of the utility model, the turntable 10 has a plurality of second mounting portions 12 arranged along its own circumference, a plurality of first mounting portions 11 and a plurality of second mounting portions 12 are arranged alternately, and each sub-mechanism 1 also includes a plurality of second bearing assemblies 50, each second bearing assembly 50 is arranged on the second mounting portion 12, and is used to carry the code piece to be read.

[0072] Specifically, a plurality of second mounting portions 12 may be provided on the turntable 10 , and the plurality of second mounting portions 12 may be arranged along the circumference of the turntable 10 , and a first mounting portion 11 may be provided between two adjacent second mounting portions 12 , and a second mounting portion 12 may be provided between two adjacent first mounting portions 11 .

[0073] A second bearing assembly 50 is provided on each second mounting portion 12, and the second bearing assembly 50 can bear the code piece to be read. The second bearing assembly 50 can be fixed on the turntable 10 and rotate with the turntable 10. Thus, as the turntable 10 rotates, the first bearing assembly 20 can switch between the standby position a and the code reading position b, and the second bearing assembly 50 is always in the standby position a on the turntable 10.

[0074] During the loading process, the first supporting component 20 and the second supporting component 50 are loaded in sequence. The code parts to be read loaded to the first supporting component 20 can be read on the current turntable 10, and the code parts to be read loaded to the second supporting component 50 can be read on other sub-mechanisms 1.

[0075] In this embodiment, a plurality of first mounting portions 11 and a plurality of second mounting portions 12 are arranged in a staggered manner, so that the first bearing assembly 20 and the second bearing assembly 50 are arranged in a staggered manner, so that the code reading assembly 30 in each sub-mechanism 1 reads a portion of the code pieces to be read on the turntable 10, and the other portion can be read in the next sub-mechanism 1. Multiple sub-mechanisms 1 can work simultaneously, so that the turntable 10 in each sub-mechanism 1 can speed up the rotation speed and achieve high-speed code reading, thereby improving the code reading efficiency.

[0076] According to some other embodiments of the utility model, the number of sub-mechanisms 1 is two, and the two sub-mechanisms 1 include a first sub-mechanism 1a and a second sub-mechanism 1b. The first supporting component 20 in the second sub-mechanism 1b obtains the code piece to be read from the second supporting component 50 in the first sub-mechanism 1a, and the second supporting component 50 in the second sub-mechanism 1b obtains the code piece to be read from the first supporting component 20 in the first sub-mechanism 1a.

[0077] Specifically, the code reading mechanism 100 may include two sub-mechanisms 1, and the two sub-mechanisms 1 have the same structure. Figure 1 As shown, the two sub-mechanisms 1 can be staggered, and the two turntables 10 can rotate synchronously. During the rotation process, the first bearing assembly 20 and the second bearing assembly 50 in the two sub-mechanisms 1 can be meshed similar to the gear 60.

[0078] The cup 200 on the first carrying assembly 20 in the first sub-mechanism 1a can be acquired by the second carrying assembly 50 in the second sub-mechanism 1b, and the cup 200 on the second carrying assembly 50 in the first sub-mechanism 1a can be acquired by the second carrying assembly 50 in the first sub-mechanism 1a.

[0079] Thus, the cup 200 loaded onto the first bearing assembly 20 of the first sub-mechanism 1a can be read in the first sub-mechanism 1a, and the cup 200 loaded onto the second bearing assembly 50 of the first sub-mechanism 1a can be read in the second sub-mechanism 1b. The two sub-mechanisms 1 cooperate to perform code reading synchronously, and reliable code reading can be performed during the high-speed rotation of the turntable 10, which is conducive to improving code reading efficiency.

[0080] In some specific embodiments of the present invention, the axes of the two rotating disks 10 are parallel, and each sub-mechanism 1 further includes: a gear 60, which is coaxially connected to the corresponding rotating disk 10, and the two gears 60 are meshed for transmission.

[0081] Specifically, each sub-mechanism 1 includes a gear 60, so the code reading mechanism 100 includes two gears 60 and two turntables 10. For ease of explanation, the two gears 60 can be defined as a first gear 60 and a second gear 60, and the two turntables 10 can be defined as a first turntable 10a and a second turntable 10b.

[0082] The diameter of the first rotating disk 10a can be the same as the diameter of the second rotating disk 10b. The first rotating disk 10a and the first gear 60 can be coaxially arranged and connected by a transmission shaft, and the second rotating disk 10b and the second gear 60 can also be coaxially arranged and connected by another transmission shaft. The axes of the two rotating disks 10 can be both vertical, and the first gear 60 and the second gear 60 can be meshed and driven, so that the first rotating disk 10a and the second rotating disk 10b can rotate synchronously, so as to facilitate the second sub-mechanism 1b to obtain the cup 200 from the first sub-mechanism 1a.

[0083] In some specific embodiments, Figure 1 As shown, in the radial direction of the turntable 10, the code reading assembly 30 in the first sub-mechanism 1a can be arranged on the side of the first turntable 10a away from the second turntable 10b, and the code reading assembly 30 in the second sub-mechanism 1b can be arranged on the side of the second turntable 10b away from the first turntable 10a.

[0084] In some other optional embodiments, the code reading mechanism 100 may further include an alignment component, which may be disposed on the first supporting component 20 for aligning the code reading component.

[0085] In summary, the code reading mechanism 100 of the embodiment of the utility model is provided with a movable first bearing assembly 20 on the turntable 10 for bearing the code pieces to be read, so that the first bearing assembly 20 rotates together with the follower turntable 10, and at the same time, a cam assembly 40 is used to guide the first bearing assembly 20 to move between the standby station a and the code reading station b, so that the adjacent code pieces to be read on the turntable 10 can be axially misaligned during code reading, and the distance between adjacent code pieces to be read is increased to avoid mutual interference between adjacent code pieces to be read, so that the code reading assembly 30 can read codes normally. Compared with the prior art, the code reading mechanism 100 of the embodiment no longer requires an alignment mechanism to read codes normally, thereby simplifying the structure of the code reading mechanism 100 and reducing the cost of the code reading mechanism 100.

[0086] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
