Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.

Through long-term observation and research, the inventors found that various errors are involved in assembling the high-voltage battery. For example, an automated guided vehicle (Automated Guided Vehicle, AGV) may have a positioning error when dragging a first substrate (e.g., a pallet), i.e., the AGV will first reach a predetermined position during assembly, which may result in the positioning error described above. Similarly, when assembled layer by layer, the spreader and the second substrate (e.g., battery rack) can also introduce errors that can have a significant impact on the efficiency and accuracy of the assembly.

In order to solve the above problems, the inventor first proposes adding an intermediate substrate (such as a positioning frame with a frame structure) disposed between the first substrate and the second substrate, and connecting the two substrates through the intermediate substrate, so as to improve the positioning accuracy.

For a better understanding of the inventive concept, reference will be made to the following description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic view of an assembling device according to an embodiment of the utility model.

Referring to fig. 1, the assembly device 10 includes a first substrate 11, an intermediate substrate 12, and a second substrate 13, wherein the first substrate 11 is carried by an AGV during assembly, the intermediate substrate 12 is assembled between the first substrate 11 and the second substrate 13, and the second substrate 13 is used for carrying a high-voltage battery.

Specifically, the intermediate substrate 12 is mounted on the first substrate 11, and first floating modules 121 are respectively provided at least two positions of the intermediate substrate 12, and the first floating modules 121 are elastically coupled to the first positioning grooves 111 on the first substrate 11. By so doing, when the intermediate substrate 12 is assembled onto the first substrate 11, the first floating module 121 interacts with the first positioning groove 111 to achieve the limitation between the two layers of substrates, i.e., the first positioning groove 111 limits the first floating module 121 such that the error between the two layers of substrates is less than a specified threshold (e.g., 5 mm).

Also, the second substrate 13 is mounted on the intermediate substrate 12, and second floating modules 131 are respectively provided at least two positions of the second substrate 13, wherein the second floating modules 131 are elastically coupled to the second positioning grooves 122 on the intermediate substrate 12. When the second substrate 11 is assembled on the intermediate substrate 12, the second floating module 131 interacts with the second positioning groove 122 to achieve a limiting effect between the two layers of substrates, that is, the second positioning groove 122 limits the second floating module 131, so that a positioning error between the two layers of substrates is smaller than a specified threshold.

In one embodiment, a plurality of through holes are also provided at the edges of one or more of the first, second and intermediate substrates. The fastening bolts 14 cooperate with the transition sleeve to effect a tight connection of the first, second and/or intermediate base plates. And after the high-voltage battery and the automobile to be assembled are aligned, tightening the fastening bolts of the high-voltage battery and the automobile to be assembled to a specified torque so as to complete the assembly of the high-voltage battery.

Through setting up first, second floating module on intermediate base plate 12 and second base plate 13 for all have spacing effect each other between the adjacent base plate, thereby promoted positioning accuracy and stability.

Fig. 2A is a schematic diagram of a first floating module structure according to an embodiment of the utility model, and fig. 2B is a schematic diagram of a first floating module structure according to an embodiment of the utility model at another view angle.

As shown in fig. 2A, the first floating module 121 includes: a first support column 21 having a first end fixedly connected to the intermediate substrate 12; a first ball member 22 coupled to the second end of the first support column 21, and a bottom of a ball 221 (e.g., a universal ball) of the first ball member 22 is located in the first positioning groove 111; a first spring group 23 arranged along the extending direction of the first support column 21 for providing cushioning between the first substrate 11 and the intermediate substrate 12. In addition, the first support column 21 may be fixedly connected to the intermediate substrate 12 via a flange 24.

The spring group 23 will act as a buffer during the assembly of the intermediate substrate 12 to the first substrate 11. Since there is a positioning error at the time of assembly, the first positioning groove 111 and the ball 221 interact with each other, so that the positioning error is reduced.

In one embodiment, the second end of the first support column 21 includes a cavity for receiving the first ball member 22. Similarly, the second end of the first support column 21 may also include other attachment mechanisms for attaching the first ball member 22.

In one embodiment, the first ball member 22 is configured such that the balls 221 remain rolling when subjected to pressure in other directions. It will be appreciated that the first ball member 22 may be a separate component (e.g., a ball joint) or may be an assembly of multiple discrete components. For example, the first ball member 22 may include a sleeve to accommodate the spring plate and the ball 221, and thus when the ball 221 is pressed, the spring plate may provide elasticity without affecting the rolling of the ball in all directions.

The first positioning groove 111 may be a V-groove, and thus, when the balls 221 deviate from the groove bottom due to an assembly error, the sidewalls of the V-groove will apply resistance to the balls 221 to achieve a limit. The angle of the V-groove (i.e., the angle of the sidewall to the horizontal) may be any angle from 10 to 80 degrees, depending on the application. In another embodiment, the first positioning groove 111 may be an arc groove, and the depth and length of the arc groove may be adjusted according to the application requirement.

As shown in fig. 2B, a limiting assembly is further provided near the first floating module 121, and includes: the limiting block 112 is arranged on the first substrate 11, and a limiting groove is formed in the limiting block 112; the limiting rod 123 is disposed on the intermediate substrate 12, and the radius of the end of the limiting rod 123 is smaller than the radius of the limiting groove 112, so that the end of the limiting rod 123 can extend into the limiting groove 112. Since the stopper rod 123 and the first support column 21 are both fixed to the intermediate substrate 12, they will move simultaneously. It will be appreciated that the cooperation of the limiting rod 123 and the limiting groove 112 can limit the relative movement range of the first substrate 11 and the intermediate substrate 12. In other words, the limiting assembly limits the relative movement amount of the intermediate substrate 12 and the first substrate 11 by limiting the movement distance of the limiting rod 123 to limit the limiting effect of the balls 221.

As shown in fig. 2C, the radius of the end of the stopper rod 123 is r1, and the radius of the stopper groove 112 is r2. If the preset alignment positions are concentric with each other, the maximum movement amount corresponding to the limiting component is the difference between r2 and r 1. It will be appreciated that the end of the stop bar 123 and the stop recess 112 may have other shapes, such as rectangular or other polygonal shapes, when the relative movement of adjacent substrates is fixed in a certain direction.

Fig. 3A is a schematic diagram of a second floating module according to an embodiment of the utility model, and fig. 3B is a schematic diagram of a ball and groove structure in the second floating module according to an embodiment of the utility model.

As shown in fig. 3A, the second floating module 131 includes: a second support column 31 fixedly connected to the second substrate 13; the second ball member 32 is coupled to the second support column 31, and the bottom of the ball 321 in the second ball member 32 is located in the second positioning groove, wherein the second positioning groove is disposed in the stopper 124 on the intermediate substrate 12. The second floating module 131 further includes a second spring group 33 arranged along the extending direction of the second support column 31 for providing a buffer between the second substrate 13 and the intermediate substrate 12. In this embodiment, the second ball member 32 may be a ball-and-socket ball, such as a self-lubricating ball-and-socket structure, which includes a ball seat, balls, an elastomer, and a reservoir for lubricant that enters the mounting cavity when the balls are pressurized.

Similarly, the second end of the second support column 31 may include a cavity for receiving the second ball member 32, or the second end of the second support column 21 may be connected to the second ball member 22 by other connection mechanisms.

In the present embodiment, the second positioning groove 124 is an arc-shaped groove, and the depth H of the second positioning groove is equal to or less than the radius of the ball 321. In one embodiment, the length L of the second positioning groove 124 is 3 to 8 times the radius of the ball 321 of the second ball member. It can be appreciated that the parameters of the arc type slot can be set according to the application scenario. Therefore, the second floating module 131 achieves a limiting effect with the balls 321 through the arc-shaped grooves.

In other embodiments, the second positioning groove may be a V-shaped groove, and the second ball member 321 may be a universal ball or other components with corresponding functions, which will not be described herein.

With continued reference to fig. 2A, the assembly apparatus further includes an inter-layer rolling assembly for providing inter-layer support and sliding. The interlayer rolling assembly includes: a sleeve 125 fixedly connected to the intermediate substrate 12; a third ball member 126 (e.g., a ball joint) is disposed within the sleeve 125 and is resiliently coupled to the pad 113 on the first substrate 11. It will be appreciated that in other embodiments, the spacer 113 may be omitted, or may be replaced by a groove or a guiding spacer, rail or other component. It will be appreciated that the interlayer rolling assembly may be disposed between the first substrate 11 and the intermediate substrate 12, or between the second substrate 13 and the intermediate substrate 12, depending on the application requirements.

Although in the embodiment the first and second floating modules are of different types, in a particular application both may be floating sliders of the same type, in other words the first and second floating modules may take the same structure. Likewise, the number and distribution of the first and second floating modules may be specifically adjusted according to the application requirements.

FIG. 4 is a schematic diagram of a floating module distribution according to an embodiment of the present utility model.

As shown in fig. 4, the assembly device in fig. 1 is projected in a vertical direction as a rectangle, and the assembly device may be provided with a first floating module 121 at four corner regions, and a second substrate may be provided with a second floating module 122 at a central axis region. It will be appreciated that the number and distribution of floating modules required may be different in different scenarios. For example, the mounting device may provide the first floating modules 121 in two diagonal areas (hatched portions), or may provide the first floating modules 121 in three of four corner areas. Also, the assembly device may be provided with more floating modules, such as 6 floating modules at the edge region of the intermediate substrate 12. Similarly, the number and distribution of the second floating modules can be adjusted accordingly, which is not limited to the case described in the above embodiment.

In another embodiment, the first floating module may be used interchangeably with the second floating module, and will not be described in detail herein.
