For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal encapsulation of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] To address the problem that heat-sealed edges in related technologies often lose their insulation properties, this invention provides a battery heat-sealing device.

[0040] The battery hot-edge device of this utility model embodiment includes a placement seat 1 and multiple hot-edge components 2.

[0041] The placement seat 1 is used to place the battery, and multiple hot-edge components 2 are spaced apart in the circumferential direction of the placement seat 1. The hot-edge components 2 can move between a first position and a second position. The hot-edge components 2 include an insulating hot-edge block 201 and a heating element 202. The heating element 202 is connected to the insulating hot-edge block 201. In the first position, the insulating hot-edge block 201 presses against the battery. In the second position, the insulating hot-edge block 201 is detached from the battery.

[0042] By configuring the hot edge assembly 2 to include an insulating hot edge block 201, the insulating hot edge block 201 in this application, compared with the hot edge block with Teflon coating on the surface in the related technology, will not lose its insulation performance due to wear. At the same time, it can not only meet the hot edge requirements of the battery, but also avoid the problem of short circuit of the battery during hot edge.

[0043] The following is in conjunction with the appendix Figure 1-3 The battery hot-iron edge device of this utility model embodiment will be further described below.

[0044] The battery hot-edge device of this utility model embodiment includes a placement seat 1 and multiple hot-edge components 2.

[0045] The placement seat 1 is used to place the battery.

[0046] like Figure 1 As shown, multiple hot-edge components 2 are spaced apart in the circumferential direction of the placement seat 1, and the hot-edge components 2 can move between a first position and a second position;

[0047] The edge-heating assembly 2 includes an insulating edge-heating block 201 and a heating element 202. The heating element 202 is connected to the edge-heating block. In the first position, the insulating edge-heating block 201 presses against the battery; in the second position, the insulating edge-heating block 201 is detached from the battery.

[0048] Optionally, the insulating edge-heating block 201 can be a ceramic edge-heating block, which can conduct heat and also has insulating properties.

[0049] Optionally, the heating element 202 may be a resistance heater.

[0050] By setting the hot edge assembly 2 to include an insulating hot edge block 201, the insulating hot edge block 201 in this application, compared with the hot edge block with a Teflon coating on its surface in the related technology, will not lose its insulation performance due to wear. At the same time, it can not only meet the hot edge requirements of the battery, but also avoid the problem of short circuit in the battery during hot edge.

[0051] In some embodiments, the battery hot-edge device of this utility model further includes a vacuum generating device 3, and a vacuum adsorption hole 101 is provided on the placement seat 1. The vacuum generating device 3 is connected to the vacuum adsorption hole 101 through a pipeline.

[0052] Furthermore, a vacuum pressure gauge 4 is installed on the pipeline between the vacuum generating device 3 and the vacuum adsorption hole 101.

[0053] By installing a vacuum pressure gauge 4 on the pipeline between the vacuum generator 3 and the vacuum adsorption hole 101, the vacuum level in the vacuum adsorption hole 101 can be monitored in real time, thus avoiding the problem of vacuum leakage when adsorbing batteries.

[0054] In some embodiments, the hot edge assembly 2 further includes a hot edge fixing seat 203, and an insulating hot edge block 201 is disposed on the hot edge fixing seat 203; the hot edge fixing seat 203 has a heating mounting hole 2031, and a heating element 202 is disposed in the heating mounting hole 2031.

[0055] As shown in the figure, the heating element 202 is a cylindrical resistance heater that can be inserted into the heating mounting hole 2031. The hot edge fixing seat 203 can transfer the heat of the heating element 202 to the insulating hot edge block 201 so that the insulating hot edge block 201 can hot edge the battery.

[0056] In order to facilitate the real-time acquisition of temperature data of the insulating hot edge block 201, a temperature sensor 7 can be provided on the hot edge fixing base 203. Since the hot edge fixing base 203 can transfer the heat of the heating element 202 to the insulating hot edge block 201, the temperature sensor 7 can be connected to the hot edge fixing base 203 to achieve the effect of acquiring the temperature data of the insulating hot edge block 201.

[0057] Meanwhile, it is understandable that the temperature sensor 7 can also be connected to the insulating hot edge block 201 to further accurately collect the temperature data of the insulating hot edge block 201.

[0058] In some embodiments, the hot-edge heating device of this utility model further includes a moving component 5, which is connected to a plurality of hot-edge heating components 2 to drive the hot-edge heating components 2 to move between a first position and a second position.

[0059] Furthermore, the moving component 5 includes a multi-claw cylinder 501, which is located below the placement seat 1. The multi-claw cylinder 501 includes a cylinder body 5011 and a plurality of pneumatic fingers 5012 spaced apart circumferentially along the cylinder body 5011. The plurality of pneumatic fingers 5012 are respectively connected to a plurality of hot edge components 2. The plurality of pneumatic fingers 5012 can move radially along the cylinder body 5011 to drive the hot edge components 2 to move between a first position and a second position.

[0060] like Figure 2 As shown, the multi-claw cylinder 501 includes four pneumatic fingers 5012 spaced apart circumferentially along the cylinder body 5011. The corresponding number of hot edge components 2 is also four. The four pneumatic fingers 5012 are respectively connected to the four hot edge components 2. The four pneumatic fingers 5012 respectively drive the four hot edge components 2 to move radially along the cylinder body 5011, thereby causing the hot edge components 2 to move between the first position and the second position.

[0061] The movement path of the four pneumatic fingers 5012 is set to move radially along the cylinder 5011, so that the movement path of the hot edge assembly 2 is also radially along the cylinder 5011. The clamping force applied by the hot edge assembly 2 to the battery is also in the radial direction of the cylinder 5011. During the hot edge process, the battery will not have the problem of vertical displacement.

[0062] In some embodiments, the movable component 5 further includes an adapter 502, which is disposed between the pneumatic finger 5012 and the hot edge fixing seat 203 to connect the hot edge fixing seat 203 and the pneumatic finger 5012.

[0063] like Figure 1 As shown, the hot edge fixing base 203 includes a first pad 5021 and a second pad 5022 stacked together. The first pad 5021 is connected to the hot edge fixing base 203, and the second pad 5022 is connected to the pneumatic finger 5012. In order to isolate the heat of the hot edge fixing base 203, the first pad 5021 can be made of bakelite. In order to improve the connection strength between the second pad 5022 and the pneumatic finger 5012, the second pad 5022 can be made of metal.

[0064] In some embodiments of the present invention, a lifting component 6 is further included, which is connected to the placement seat 1 to drive the placement seat 1 to rise and fall.

[0065] Furthermore, the lifting assembly 6 includes a plurality of lifting cylinders 601, which are spaced apart on the outer periphery of the multi-claw cylinder 501 along the circumference of the multi-claw cylinder 501; the moving ends of the plurality of lifting cylinders 601 are connected to the placement seat 1 to drive the placement seat 1 to rise and fall.

[0066] By setting up the lifting cylinder 601, on the one hand, when the battery to be heated is placed on the placement seat 1, the lifting cylinder 601 can drive the placement seat 1 to rise and fall, thereby moving the battery to be heated to a preset position, which is a position that facilitates the heating assembly 2 to heat the battery.

[0067] On the other hand, after the battery edge is heated, the lifting cylinder 601 can lift the heated battery upwards to facilitate subsequent processes, such as facilitating the mechanical clamping components of subsequent processes to clamp the heated battery.

[0068] In some embodiments, the lifting assembly 6 further includes a plurality of lifting connectors 602, one end of which is connected to the lifting cylinder 601 and the other end of which is connected to the placement seat 1.

[0069] like Figure 2 As shown, the lifting connector 602 extends radially from the cylinder body 5011 of the multi-claw cylinder 501. The inner end of the lifting connector 602 in the radial direction of the cylinder body 5011 is connected to the placement seat 1, and the outer end of the lifting connector 602 in the radial direction of the cylinder body 5011 is connected to the lifting cylinder 601, thereby facilitating the lifting cylinder 601 to drive the placement seat 1 to rise and fall.

[0070] In some embodiments, the battery hot-edge device of this utility model further includes a support base 8, as shown in the figure, where a multi-claw cylinder 501 and a lifting cylinder 601 are both disposed on the support base 8.

[0071] In practical applications, multiple battery hot-stamping devices according to this utility model can be set up to improve production efficiency, for example, such as Figure 3 As shown, two battery edge-heating devices of this utility model are arranged side by side. The two battery edge-heating devices of this utility model can heat two batteries at the same time, thereby greatly improving the edge-heating efficiency of the battery edge-heating devices of this utility model.

[0072] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
