Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a transmission device. Background Art

[0002] During the production process of battery modules, some manual processing techniques are involved. The battery modules are transported through a carrier plate. The weight and volume of the battery modules are relatively large, making them inconvenient to move. Therefore, in the prior art, an automated conveyor or a semi-automated conveyor is used to transport the battery modules, and the staff processes the battery modules on one side of the conveyor. However, this conveyor causes the staff to be unable to freely control the movement of the battery modules. In the prior art, most of the non-powered rolling devices adopt a scheme in which multiple rollers are arranged side by side along the transportation direction. The axial direction of the rollers is perpendicular to the transportation direction of the carrier plate, and the length of the rollers is adapted to the width direction of the transmission device, which has relatively precise restrictions on the length of the rollers. However, when manufacturing the rollers, the raw materials may not be able to match rollers of a suitable length. Smaller-length rollers are relatively easy to purchase on the market, but the number of rollers arranged is large, and the installation efficiency is low. If they are laid at intervals, it will affect the stability of the carrier plate during the transmission process.

[0003] Therefore, it is urgent to design a transmission device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a transmission device that can make full use of small-sized rollers, appropriately reduce the number of rollers laid, and ensure the stability of the transmission of the carrier plate.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0034] This embodiment provides a transmission device, which can make full use of small-sized rollers 212, appropriately reduce the laying number of the rollers 212, and ensure the stability of the transmission of the carrier plate 40. As Figure 1 shown, the transmission device includes a support assembly 10 and a multi-row roller mechanism 20. The multi-row roller mechanism 20 extends along a first direction (the X direction in the figure) and is installed on the support assembly 10. The multi-row roller mechanisms 20 are arranged at intervals along a second direction (the Y direction in the figure, the Y direction is perpendicular to the X direction). The roller mechanism 20 includes at least two roller assemblies 21 arranged at intervals along the first direction. The roller assembly 21 includes a plurality of rollers 212 arranged in sequence along the first direction. A gap 22 is formed between two adjacent roller assemblies 21 in the same roller mechanism 20, and the gap 22 is covered by the projection of the roller assemblies 21 in the other roller mechanisms 20 in the second direction.

[0035] The above-mentioned transmission device, by setting the multi-row roller mechanism 20, first of all, the width of the multi-row roller mechanism 20 can conform to the size of the carrier plate 40 in the second direction during transmission. The rollers 212 used are small-sized rollers 212, and there is no need to separately manufacture rollers 212 with the same length as the carrier plate 40. The purchased rollers 212 are fully utilized for assembly. In addition, the adjacent roller assemblies 21 in the same roller mechanism 20 are arranged at intervals, which can appropriately reduce the use of rollers 212. At the same time, the gap 22 between two adjacent roller assemblies 21 is covered by the projection of other roller mechanisms 20 in the second direction, so that in the second direction, there are rollers 212 at any position of the multi-row roller assemblies 21, that is, during the transmission of the carrier plate 40, the bottom is supported by the rollers 212. While reducing the number of rollers 212 used, the stability of the transmission of the carrier plate 40 is ensured.

[0036] Optionally, as Figure 1 shown, several roller assemblies 21 on adjacent roller mechanisms 20 are arranged staggeredly in the first direction; several roller assemblies 21 on two roller mechanisms 20 separated by one roller mechanism 20 are arranged in alignment in the first direction. Exemplarily, as Figure 1 shown, the roller mechanism 20 is provided with five rows. The roller assemblies 21 in the first row, the third row, and the fifth row of the roller mechanisms 20 are arranged in alignment with each other. The second row and the fourth row are staggered from the above three rows by a certain distance in the first direction, so that the gaps 22 in the first row, the third row, and the fifth row of the roller mechanisms 20 are blocked. The staggered distance is greater than the distance of the gap 22, so that the gaps 22 in the second row and the fourth row are also blocked by the first row, the third row, and the fifth row. With this setting, the distance between the two aligned roller mechanisms 20 is relatively small. When the carrier plate 40 reaches the position of the gap 22 during the transmission process, the support for the carrier plate 40 is relatively stable, and the transmission device is symmetrically arranged in the width direction. When the carrier plate 40 reaches the position of the gap 22 during the transmission process, the forces on both sides of the carrier plate 40 are balanced.

[0037] In other embodiments, two or more roller mechanisms 20 can also be spaced between two aligned roller mechanisms 20, which is not limited herein.

[0038] Optionally, in the multi-row roller mechanism 20, at least two roller assemblies 21 protrude along the first direction at each end in the first direction, and the outer ends of the roller assemblies 21 protruding at the same end are aligned. Through the above setting, it can be ensured that when the carrier plate 40 is input or output, at least two roller assemblies 21 support the carrier plate 40, ensuring the stability of the carrier plate 40 at both ends of the transmission device.

[0039] In this embodiment, the lengths of each roller assembly 21 are equal. With the above arrangement, during the manufacturing of the roller assemblies 21, the specifications are unified, making it not easy to make mistakes during the assembly of the roller assemblies 21. Moreover, when the roller assemblies 21 are installed on the support assembly 10, it is also not easy to install them in the wrong position.

[0040] Specifically, as Figure 2 and Figure 3 shown, the roller assembly 21 further includes a U-shaped support 211. The U-shaped support 211 extends along the first direction, and the U-shaped support 211 forms a U-shaped groove extending along the first direction. The U-shaped support 211 is installed on the support assembly 10; a plurality of rollers 212 are sequentially pivotally connected to the U-shaped support 211 along the first direction and are located within the U-shaped groove. With the above arrangement, the U-shaped support 211 serves as a carrier for the plurality of rollers 212 and is installed on the support assembly 10. It can be understood that in this embodiment, the lengths of the plurality of U-shaped supports 211 are the same, and the number of rollers 212 on each U-shaped support 211 is the same.

[0041] In other embodiments, if the lengths of the U-shaped supports 211 are different, roller assemblies 21 with different lengths can also be manufactured according to the lengths of the already formed U-shaped supports 211 on-site, which is not limited herein.

[0042] Optionally, as Figure 3 shown, the bearing plate 40 protrudes downward by two limiting protrusions 41 corresponding to each roller mechanism 20. The U-shaped support 211 is limited between the two limiting protrusions 41. With the above arrangement, when the bearing plate 40 is transported on multiple rows of roller mechanisms 20, its position is limited by the U-shaped support 211, preventing the bearing plate 40 from shifting in the second direction. In this embodiment, since there are five rows of roller mechanisms 20, five groups of the two limiting protrusions 41 are provided on the lower side of the bearing plate 40. In other embodiments, it can be adaptively adjusted according to the number of roller mechanisms 20.

[0043] In other embodiments, two limiting grooves (not shown) are provided on the lower side of the bearing plate 40 corresponding to each roller mechanism 20. The U-shaped support 211 protrudes with protrusions, and the protrusions and the limiting grooves are arranged in one-to-one correspondence. The protrusions can slide relative to the limiting grooves. With the above arrangement, the protrusions can also prevent the bearing plate 40 from shifting in the second direction.

[0044] Optionally, as Figure 1As shown in the figure, the support assembly 10 includes a plurality of support members 11. The plurality of support members 11 are arranged in sequence along the first direction, and the roller assembly 21 can connect two adjacent support members 11. Through the above settings, different lengths of the support assembly 10 can be assembled by setting different numbers of support members 11. At the same time, the roller assembly 21 serves both as a transported part and a connecting part. A connecting position 12 is formed between two adjacent support members 11, giving full play to the role of the roller assembly 21. In this embodiment, there are four connecting positions 12 between two adjacent support members 11, that is to say, there are five support members 11. In other embodiments, the number of support members 11 can be adaptively adjusted according to the transmission distance, which is not limited herein. Of course, the support members 11 can also be assisted in connection by other connecting members, which is not limited herein.

[0045] Optionally, a plurality of through holes (not shown) are formed in the U-shaped support body 211, and bolts pass through the through holes and are connected to the corresponding support members 11 to realize the connection between two adjacent support members 11.

[0046] Optionally, as Figure 2 shown in the figure, the support assembly 10 includes two limiting members 13. The two limiting members 13 are arranged at intervals along the second direction, and each limiting member 13 extends along the first direction. Both sides of the bearing plate 40 can be limited by the two limiting members 13 respectively. The setting of the limiting members 13 can further prevent the bearing plate 40 from moving in the second direction during the transmission process.

[0047] Optionally, the limiting member 13 is a pipe. It can appropriately reduce the weight of the support member 11, facilitating the handling by personnel.

[0048] Optionally, the support assembly 10 further includes a support frame 111 and a support table 112. The support table 112 is arranged on the top of the support frame 111. The two limiting members 13 are respectively arranged on both sides of the support table 112, and the roller assembly 21 is arranged on the support table 112. Through the above settings, the support frame 111 can support the support table 112 to a suitable height. Among them, the U-shaped support body 211 is connected to the support table 112.

[0049] Optionally, as Figure 1 shown in the figure, a plurality of part boxes 30 are arranged at intervals on both sides of the support assembly 10 extending along the first direction. The part boxes 30 are used to place different assembly parts, facilitating the access by the operators.

[0050] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
