[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0038] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0039] 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.

[0040] 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.

[0041] According to one aspect of the present invention, Figures 1 to 3As shown, a restraining device is provided, which is applied to battery production, including: a base plate 1 and a first baffle plate 2 and a second baffle plate 3 spaced apart on the base plate 1 along a first direction (X direction in the figure); and a push-pull plate 4, a pressure plate 5 and a first driving mechanism, wherein the push-pull plate 4 is movably arranged between the first baffle plate 2 and the second baffle plate 3, and respectively forms a first accommodating groove 6 with the first baffle plate 2 and a second accommodating groove 7 with the second baffle plate 3, the first accommodating groove 6 is used to place the pressure plate 5, and the second accommodating groove 7 is used to place the battery 26; the first driving mechanism is located on a side of the first baffle plate 2 away from the second baffle plate 3, and its output end extends through the first baffle plate 2 into the first accommodating groove 6, and the output end can move the push-pull plate 4 in the first direction toward the direction close to the second baffle plate 3 by pressing the pressure plate 5.

[0042] Specifically, in the present embodiment, the first baffle plate 2 and the second baffle plate 3 are spaced apart on the bottom plate 1 along the first direction, and the push-pull plate 4 is movably arranged on the bottom plate 1 and is located between the first baffle plate 2 and the second baffle plate 3, so that when the first driving mechanism presses the pressure plate 5 through its output end, the pressure plate 5 can push the push-pull plate 4 to move along the first direction toward the direction close to the second baffle plate 3, thereby reducing the size of the second accommodating groove 7 formed by the push-pull plate 4 and the second baffle plate 3 in the first direction.

[0043] In practical applications, the second receiving groove 7 is used to place the battery 26. When the size of the second receiving groove 7 in the first direction is reduced, the multiple batteries 26 placed in the second receiving groove 7 are squeezed in the first direction, so that each battery 26 is restrained. The number of batteries 26 placed can be set according to actual production needs. When multiple batteries 26 are placed in the second receiving groove 7, the multiple batteries 26 can be arranged at intervals along the first direction to restrain each battery 26.

[0044] In the above embodiment, by using the pressure plate 5 to pressurize the push-pull plate 4, the structure of the entire restraint device is relatively simple, and there is no need to set more complex parts, and there is no special requirement for the pressure plate 5, which reduces the production cost. In addition, by using the pressure plate 5 to pressurize the battery 26, the displacement of the output end of the first drive mechanism and the moving distance of the push-pull plate 4 in the first direction close to the second baffle 3 can be easily converted, which simplifies the control logic of the device.

[0045] Furthermore, the use of the pressure plate 5 to apply pressure makes the first drive mechanism's pressure on the push-pull plate 4 more uniform, thereby improving the uniformity of the force applied to the battery 26. Moreover, after the battery 26 is restrained, if it needs to be unrestrained, the pressure plate can be removed from the first receiving groove 6 to restore the push-pull plate 4 to its initial position before the restraint, thereby simplifying the subsequent unrestraining method. In addition, the output end of the first drive mechanism extends through the first baffle plate 2 into the first receiving groove 6. On the one hand, the first baffle plate 2 can play a certain guiding and supporting role on the output end. On the other hand, it can also prevent the movement of the output end of the first mechanism from being disturbed by the external environment, thereby improving the reliability of the device.

[0046] Alternatively, if Figures 1 to 3 As shown, it also includes a third baffle 8, which is spaced apart at a side of the first baffle 2 away from the second baffle 3, and forms a third accommodating groove 9 with the first baffle 2, and the third accommodating groove 9 is used for pre-placing the pressure plate 5; the output end of the first driving mechanism can sequentially pass through the third baffle 8 and the first baffle 2 and extend into the first accommodating groove 6.

[0047] Specifically, in this embodiment, by arranging the third baffle plate 8 at a distance from the side of the first baffle plate 2 away from the second baffle plate 3, a third receiving groove 9 can be formed between the third baffle plate 8 and the first baffle plate 2. When the restraint is subsequently released or the device is idle, the pressure plate can be pre-stored in the third receiving groove 9 to avoid loss or damage of the pressure plate 5. In actual applications, the size of the pressure plate 5 can be set according to actual needs, and the utility model does not limit this.

[0048] Optionally, a first avoidance hole is provided on the first baffle plate 2, and a second avoidance hole is provided on the third baffle plate 8. The first avoidance hole and the second avoidance hole are concentric holes for avoiding the output end of the first driving mechanism.

[0049] Specifically, in this embodiment, the output end of the first driving mechanism passes through the second avoidance hole and the first avoidance hole in sequence, and extends into the first accommodating groove 6, so as to be pressed against the pressing plate 5. The first avoidance hole and the second avoidance hole are concentric holes, that is, in the first direction, the centers of the first avoidance hole and the second avoidance hole coincide, thereby guiding and limiting the output end of the first driving mechanism.

[0050] Alternatively, if Figure 2 As shown, it also includes a guide rod 10, which is arranged at the side of the bottom plate 1 along the first direction. A guide hole is arranged on the push-pull plate 4. The guide rod 10 passes through the guide hole, so that the push-pull plate 4 is movably arranged on the bottom plate 1.

[0051] Specifically, in this embodiment, the push-pull plate 4 is movably arranged on the bottom plate 1 through the guide rod 10, so that the push-pull plate 4 can always move along the first direction when the pressure plate 5 applies pressure to it, further improving the reliability of the device. Among them, the first baffle plate 2, the second baffle plate 3 and the third baffle plate 8 can all be passed through and fixed on the guide rod 10 to improve the stability of the device. In practical applications, two or more guide rods 10 can be provided, respectively located on both sides of the bottom plate 1, and can be specifically provided according to needs.

[0052] Alternatively, if Figure 2 As shown, the first driving mechanism includes a first driving member 11 and at least one push rod 12 connected to the first driving member 11 . The first driving member 11 can cause the at least one push rod 12 to press against the pressure plate 5 .

[0053] Specifically, in this embodiment, the first driving mechanism includes a first driving member 11 and a push rod 12, and the push rod 12 is directly connected to the first driving member 11, so that the first driving member 11 drives the push rod 12 in the first direction. There can be multiple push rods 12, all connected to the first driving member 11, so that the first driving mechanism exerts a more uniform pressure on the pressure plate 5.

Among them, the first driving member 11 can be a motor, and each push rod 12 is connected to the output shaft of the motor. In practical applications, the output shaft of the motor can also be directly pressed against the pressing plate 5, that is, the output end of the first driving mechanism can be either the output shaft of the motor or the push rod 12 connected to the output shaft.

[0055] Alternatively, if Figures 1 to 3 As shown, when a plurality of batteries 26 are placed in the second accommodating groove 7 at intervals along the first direction, the first driving member 11 is pressed against the pressure plate 5 through four push rods 12, so that the push-pull plate 4 can move in the first direction toward the direction close to the second baffle 3 to restrain the plurality of batteries 26.

[0056] Specifically, in this embodiment, when a plurality of batteries 26 are placed in the second receiving slot 7, each first driving member 11 is connected to four push rods 12 to disperse the pressure applied by the first driving mechanism on the pressure plate 5, avoid damage to the pressure plate 5, and make the restraining force on each battery 26 more balanced.

[0057] Alternatively, if Figures 1 to 3As shown, it also includes a plurality of partitions 13 , which are spaced apart and movably disposed in the second receiving groove 7 along a first direction, and a single battery 26 is placed between two adjacent partitions 13 .

[0058] Specifically, in this embodiment, a plurality of partitions 13 are spaced apart along the first direction, so that each battery 26 can be arranged one by one in the area formed between two partitions 13, thereby avoiding mutual influence between two adjacent batteries 26 during processing or production, thereby improving production convenience.

[0059] Alternatively, if Figures 1 to 3 As shown, it also includes a base 14, a mounting frame 15 and a mounting seat 16. The first driving member 11 and the base plate 1 are both fixed on the base 14, the push rod 12 is arranged on the mounting frame 15, and the mounting seat 16 is fixed on the base 14 and is located at one end of the base plate 1 close to the first baffle 2; a guide rail 17 is arranged on the mounting seat 16 along the first direction, and the mounting frame 15 is movably assembled on the mounting seat 16 through the guide rail 17, so that the first driving member 11 can drive multiple push rods 12 to move along the first direction.

[0060] Specifically, in this embodiment, the push rod 12 is slidably assembled on the mounting seat 16 through the mounting frame 15, and the first driving member 11 is fixed on the base 14, so that the first driving member 11 drives the push rod 12 to move in the first direction toward the second baffle 3 more smoothly and stably, and can improve the driving efficiency of the first driving member 11, reduce the process time of adding constraints, improve production efficiency, and also play a certain guiding role in the movement of the push rod 12, improving the reliability and stability of the device. Among them, the specific structures of the base 14, the mounting seat 16 and the mounting frame 15 can be matched and designed according to actual needs, and the utility model does not limit this.

[0061] Alternatively, if Figure 1 to Figure 2 As shown, a limiting structure 18 is disposed on the guide rail 17, and a limiting portion 19 matching the limiting structure 18 is disposed on the mounting frame 15 to limit the movement range of the push rod 12 along the first direction.

[0062] Specifically, in this embodiment, the limiting structure 18 provided on the guide rail 17 can limit the movement of the limiting portion 19 so that the movement range of the entire push rod 12 is limited to a certain area, thereby preventing the push rod 12 from being too large or too small in displacement to affect the restraint time, thereby further improving the reliability of the device.

[0063] In actual applications, a limiting structure 18 can be set at each end of the guide rail 17. By limiting the limiting portion 19, the maximum displacement limit and the minimum displacement limit of the push rod 12 in the first direction are realized, thereby preventing the push rod 12 from pushing the push-pull plate 4 too much, causing the battery 26 to be squeezed and damaged, or the push rod 12 from returning too much and leaving the guide rail 17.
