Abstract
Description
Technical Field

[0002] The ternary positive electrode materials used in battery production are generally packaged in aluminum foil inner bags to prevent the ternary positive electrode materials from contacting the air, thereby preventing the ternary positive electrode materials from chemically reacting with oxygen and water in the air. Generally, after the ternary positive electrode materials are loaded into the aluminum foil inner bag, a sealing device is required to seal the aluminum foil inner bag.
[0003] For example, a Chinese patent application numbered CN201120020477.8 discloses a packaging sealing machine, which includes a workbench with a heated copper block above the workbench. An electric heater is installed inside the copper block, and a power cord of the electric heater is connected to a temperature controller and a time relay. A cylinder is also provided above the workbench, and a push rod of the cylinder is connected to the copper block.

[0038] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0039] like Figures 1 to 3 As shown, a transverse sealing device 10 of an embodiment includes a bracket 10a, a horizontal driving member 100, a fixed bracket 200, a movable bracket 300 and at least two heating plate assemblies 400, the movable bracket 300 is connected to the output end of the horizontal driving member 100, and there is a preset distance between two adjacent heating plate assemblies 400 in the vertical direction. Each of the heating plate assemblies 400 includes a first heating plate 410 and a second heating plate 420, the first heating plate 410 is fixedly connected to the movable bracket 300, and the second heating plate 420 is fixedly connected to the fixed bracket 200, and the first heating plate 410 and the second heating plate 420 are located in the same horizontal direction, so that the horizontal driving member 100 drives the first heating plate 410 to approach or move away from the second heating plate 420 when working.
[0040] In this embodiment, there are two heating plate assemblies 400, each of which is fixedly connected to the movable bracket 300, and each of which is fixedly connected to the fixed bracket 200. The movable bracket 300 is driven to move horizontally by the horizontal driving member 100, thereby driving the two first heating plates 410 to move horizontally toward the corresponding second heating plates 420, until the two first heating plates 410 abut against the corresponding second heating plates 420, and the packaging bag with the bag opening located between the first heating plate 410 and the second heating plate 420 is heated and sealed. Compared with the longitudinal sealing device of the traditional technology, the present disclosure does not need to lay the packaging bag flat or bend the bag opening before heating and sealing, which improves the convenience of packaging, and the horizontal driving member 100 can perform double-layer sealing after working once, which improves the sealing performance of the packaging bag and the efficiency of packaging. Further, the horizontal driving member 100 can be a cylinder or a motor.
[0041] In the above-mentioned transverse sealing device 10, the movable bracket 300 is connected to the output end of the horizontal driving member 100, the first heating plate 410 is fixedly connected to the movable bracket 300, the second heating plate 420 is fixedly connected to the fixed bracket 200, and the first heating plate 410 and the second heating plate 420 are located in the same horizontal direction. When the horizontal driving member 100 is working, it drives the movable bracket 300 to move horizontally, so that the first heating plate 410 moves horizontally toward the second heating plate 420. When the first heating plate 410 and the second heating plate 420 abut, the packaging bag is heated and sealed. Through the horizontal arrangement of the first heating plate 410 and the second heating plate 420, there is no need to lay the packaging bag flat or bend the bag mouth during packaging, which improves the convenience of packaging. On the other hand, the device is provided with at least two heating plate assemblies 400, and double-layer or multi-layer sealing operations can be performed at one time when the horizontal driving member 100 is working, thereby improving the efficiency of packaging.
[0042] In one embodiment, the preset distance is 5cm-10cm.
[0043] In this embodiment, the preset distance between two adjacent heating plate assemblies 400 is 5 cm, that is, the distance between two adjacent first heating plates 410 and two adjacent second heating plates 420 is 5 cm, so that the distance between two adjacent packaging ports after heating packaging is 5 cm.
[0044] In one embodiment, the surface of the first heating plate 410 and the surface of the second heating plate 420 are both covered with a heat-conducting layer (not shown).
[0045] It can be understood that the heat-conducting layer can make the temperature of the surface of the first heating plate 410 and the surface of the second heating plate 420 more uniform, thereby preventing the packaging bag from being scorched or burned due to excessively high local temperature of the packaging bag.
[0046] In one embodiment, the heat conductive layer is a Teflon heat conductive layer.
[0047] In this embodiment, a thermal conductive layer made of Teflon is coated on the surface of the first heating plate 410 and the surface of the second heating plate 420. Teflon has the characteristics of high temperature resistance and good thermal conductivity. Of course, in other embodiments, other thermal conductive layers with high temperature resistance and good thermal conductivity can also be used.
[0048] like Figure 2 and Figure 3 As shown, in one embodiment, the heating plate assembly 400 further includes a first temperature sensor 430 and a second temperature sensor 440 , wherein the first temperature sensor 430 is installed on the first heating plate 410 , and the second temperature sensor 440 is installed on the second heating plate 420 .
[0049] It can be understood that the first temperature sensor 430 detects the temperature of the first heating plate 410, and the second temperature sensor 440 detects the temperature of the second heating plate 420, and the first temperature sensor 430 and the second temperature sensor 440 are both electrically connected to the control system, and the horizontal driving member 100 is also electrically connected to the control system, so that when the temperature of the first heating plate 410 and the second heating plate 420 rises to a preset value, the control system drives the horizontal driving member 100 to work, thereby making the first heating plate 410 and the second heating plate 420 abut against each other to heat and seal the packaging bag.
[0050] like Figure 2 and Figure 3 As shown, in one embodiment, the first temperature sensor 430 includes a plurality of first sensing units 431 , and the plurality of first sensing units 431 are installed in sequence and at intervals along the length direction of the first heating plate 410 .
[0051] In this embodiment, the number of the first sensing units 431 is three, and the three first sensing units 431 are distributed at the head, middle and tail of the first heating plate 410, that is, multiple temperatures of the first heating plate 410 are detected to make the temperature control of the first heating plate 410 more accurate.
[0052] like Figure 2 and Figure 3 As shown, in one embodiment, the second temperature sensor 440 includes a plurality of second sensing units 441 , and the plurality of second sensing units 441 are installed in sequence and at intervals along the length direction of the second heating plate 420 .
[0053] In this embodiment, the number of the second sensing units 441 is three, and the three second sensing units 441 are distributed at the head, middle and tail of the first heating plate 410, that is, multiple temperatures of the second heating plate 420 are detected to make the temperature control of the second heating plate 420 more accurate.
[0054] like Figure 2 and Figure 3 As shown, in one embodiment, the heating plate assembly 400 further includes a first protective cover 450 and a second protective cover 460 , the first heating plate 410 is provided with the first protective cover 450 at the power connection end, and the second heating plate 420 is provided with the second protective cover 460 at the power connection end.
[0055] It can be understood that both ends of the first heating plate 410 and both ends of the second heating plate 420 are connected to the wires, and the wires will produce copper scraps when used in a long-term high-temperature environment. If the copper scraps fall into the packaging bag during packaging, it will affect the quality of the ternary positive electrode material and cause problems such as excessive copper. Therefore, a first protective cover 450 is provided at the connection point between the first heating plate 410 and the wire, and a second protective cover 460 is provided at the connection point between the second heating plate 420 and the wire, so that the copper scraps are blocked and will not fall into the packaging bag.
[0056] In one embodiment, the first protective cover 450 is provided with a first through hole (not shown), and the first external wire is welded to the power connection end of the first heating plate 410 through the first through hole, so that the first external wire is electrically connected to the first heating plate 410 after passing through the first through hole.
[0057] In one embodiment, the second protective cover 460 is provided with a second through hole (not shown), and the second external wire is welded to the power connection end of the second heating plate 420 through the second through hole, so that the second external wire is electrically connected to the second heating plate 420 after passing through the second through hole.
[0058] In one embodiment, the first protective cover 450 is bonded to the power connection end of the first heating plate 410. It can be understood that the bottom of the first protective cover 450 is bonded with an adhesive layer, and the adhesive layer is a rubber pad. The first protective cover 450 is bonded to the top of the first heating plate 410 through the rubber pad to prevent copper chips from falling at the connection between the first external wire and the first heating plate 410, and to prevent the first protective cover 450 from interfering with the abutment between the first heating plate 410 and the second heating plate 420.
[0059] In one embodiment, the second protective cover 450 is bonded to the power connection end of the second heating plate 420. It can be understood that the bottom of the second protective cover 460 is bonded with an adhesive layer, and the adhesive layer is a rubber pad. The second protective cover 460 is bonded to the top of the second heating plate 420 through the rubber pad to prevent copper chips from falling at the connection between the second external wire and the second heating plate 420, and to prevent the second protective cover 460 from interfering with the abutment between the second heating plate 420 and the first heating plate 410.
[0060] The present application also provides a battery production device, comprising the transverse sealing device 10 described in any of the above embodiments.
[0061] Compared with the prior art, the present invention has at least the following advantages:
[0062] In the above-mentioned transverse sealing device 10, the movable bracket 300 is connected to the output end of the horizontal driving member 100, the first heating plate 410 is fixedly connected to the movable bracket 300, the second heating plate 420 is fixedly connected to the fixed bracket 200, and the first heating plate 410 and the second heating plate 420 are located in the same horizontal direction. When the horizontal driving member 100 is working, it drives the movable bracket 300 to move horizontally, so that the first heating plate 410 moves horizontally toward the second heating plate 420. When the first heating plate 410 and the second heating plate 420 abut, the packaging bag is heated and sealed. Through the horizontal arrangement of the first heating plate 410 and the second heating plate 420, there is no need to lay the packaging bag flat or bend the bag mouth during packaging, which improves the convenience of packaging. On the other hand, the device is provided with at least two heating plate assemblies 400, and double-layer or multi-layer sealing operations can be performed at one time when the horizontal driving member 100 is working, thereby improving the efficiency of packaging.
[0063] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
