Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0036] As Figure 1 shown, an embodiment of the present application provides a transporter, including a support base 1, a box body 2 is arranged on the support base 1 and is hermetically connected to the support base 1. The box body 2 includes six faces, and the connection positions of each face are hermetically treated to improve the sealing performance of the box body 2. The box body 2 is a chamber for accommodating a battery assembly of a solid-state battery; a sensor assembly (not shown in the figure) is arranged in the box body 2, and the sensor assembly is used to monitor the concentration value of toxic gases in the chamber under different working conditions; a controller (not shown in the figure) is also included, which is communicatively connected to the sensor assembly and is used to transmit the concentration value of toxic gases to a control module in the factory building. The control module in the factory building determines whether the toxic gases in the box body 2 exceed the standard. If they exceed the standard, the alarm device in the factory building will give an alarm, so that the operator can push the transporter to the corresponding position according to different working conditions. And an exhaust pipe 3 is also arranged on one side of the box body 2, and the exhaust pipe 3 is used to connect to exhaust ducts at different positions under different working conditions, so as to keep the toxic gases in the box body 2 below the threshold value and improve the safety of the transporter when transporting the battery assembly of the solid-state battery.

[0037] Optionally, the connection position between the exhaust pipe 3 and the box body 2 can be connected by a flange. The flange includes two flange plates, which are respectively fixed on the exhaust pipe 3 and the box body 2, and then a sealing gasket is placed between the two flange plates and they are tightly connected together with bolts, so as to achieve sealing and fixation.

[0038] Optionally, the controller can be arranged outside the box body 2. The sensing part of the sensor assembly is located inside the box body 2, while the transmission part can be located outside the box body 2. A gasket can also be arranged at the position where the sensor assembly passes through the box body 2 to achieve sealing.

[0039] Optionally, the sensor assembly includes a hydrogen sulfide monitoring sensor. When the transporter is responsible for transporting sulfide as the electrolyte of a solid-state battery, toxic gases such as hydrogen sulfide will be generated during the production process. By monitoring hydrogen sulfide, the production safety can be improved. The sensor assembly can also include a methane monitoring sensor. When the transporter is responsible for transporting polymer as the electrolyte of a solid-state battery, toxic gases such as methane will be generated during the production process. By monitoring methane, the production safety can be improved.

[0040] Optionally, full welding can be performed at the connection positions of each surface of the box body 2, or sealant can be applied at the connection positions to improve the sealing performance of the box body 2.

[0041] Optionally, the controller can be a PLC controller in the prior art.

[0042] Optionally, the controller and the sensor assembly can be fixed at any position inside the box body 2, which is not specifically limited in the embodiments of the present application, and they can be connected to the box body 2 through fasteners.

[0043] As Figure 1 shown, optionally, the transporter further includes a lifting bracket and a hydraulic cylinder. The hydraulic cylinder is connected to the lifting bracket, and the lifting bracket is connected to the support base 1. When the operator steps on the pedal, the pedal can make the hydraulic cylinder move, thereby raising the support base 1.

[0044] Optionally, both ends of the hydraulic cylinder are connected to the lifting bracket, and one end of them is connected to the pedal.

[0045] Optionally, wheels are also provided under the transporter to facilitate the movement of the transporter.

[0046] Optionally, in the embodiments of the present application, the battery assembly may include a positive electrode tab that, after drying treatment, is adhered to a hydrogen sulfide solid electrolyte membrane. Since the adhered positive electrode tab contains hydrogen sulfide, it can be hermetically transported by the transporter in the embodiments of the present application. At the same time, it can also be docked with the machine platform for the next lamination process. Of course, the battery assembly may also be a negative electrode tab that, after drying treatment, is adhered to a hydrogen sulfide solid electrolyte membrane. Since the adhered negative electrode tab contains hydrogen sulfide, it can be hermetically transported by the transporter in the embodiments of the present application. At the same time, it can also be docked with the machine platform for the next lamination process. It may also be a bare battery cell after the hydrogen sulfide solid electrolyte membrane is adhered to the positive electrode tab and the negative electrode tab respectively, that is, a solid-state battery without encapsulation. Since the hydrogen sulfide solid electrolyte membrane is clamped between the positive electrode tab and the negative electrode tab and can release hydrogen sulfide gas, it can also be transported by the transporter in the embodiments of the present application for the next encapsulation process.

[0047] Since there is currently no way to perform fully automated and fully sealed transportation of the battery assembly of a solid-state battery containing a sulfide electrolyte in the prior art, it can be transported by the transporter in the embodiments of the present application.

[0048] Optionally, the transporter in the embodiments of the present application can be applied to scenarios under three different working conditions. The first is normal transportation. When the transporter is docked with the machine platform and the sensor assembly in the box 2 monitors that the concentration of toxic gas such as hydrogen sulfide does not exceed 5 ppm, the door body 4 on the transporter is opened, and the ventilation system (including the PLC controller of the machine platform) in the machine platform is responsible for taking over the control of the hydrogen sulfide concentration in the transporter and the machine platform. When the sensor assembly in the transporter monitors that its concentration > 5 ppm at this time, the door body 4 in the transporter is closed, and the valve bodies on the intake pipe 5 and the exhaust pipe 3 in the transporter are manually opened to connect to the corresponding exhaust duct of the machine platform. The controller on the transporter continues to work and is associated with the plant-level PLC control module to control the supply and exhaust air until the concentration is controlled within 5 ppm. Since gases such as hydrogen sulfide or methane do not exceed the specified concentration value instantaneously, generally, the toxic gas in the box 2 does not exceed the standard before the transporter is docked with the machine platform. If the situation of exceeding the standard occurs, the transporter can be directly pushed to the emergency treatment site.

[0049] The second working condition is when the battery components are stored for a long time, that is, the battery components are stored in the transfer vehicle. When the sensor components in the transfer vehicle detect that the concentration of toxic gases such as hydrogen sulfide is ≤5ppm, the battery components continue to be stored; when the sensor components in the transfer vehicle detect that the concentration of toxic gases is within the range of 5pp~10ppm, the door body 4 in the transfer vehicle is closed, the valve bodies on the air intake pipe 5 and the exhaust pipe 3 in the transfer vehicle are manually opened, and the exhaust duct corresponding to the temporary storage place is connected. The controller continues to work and is associated with the plant-level PLC control module to control the supply and exhaust air until the concentration is controlled within 5ppm.

[0050] The third working condition is that if the factory suddenly loses power and cannot operate, the battery components on the transfer vehicle need to be pushed to the emergency treatment site. Because the emergency treatment site has a backup power supply, the toxic gas in the transfer vehicle can be monitored. At the same time, the emergency treatment site also has corresponding exhaust ducts.

[0051] Optionally, the threshold value of the toxic gas monitored in the box 2 can also be adjusted at any time for monitoring different toxic gases.

[0052] Optionally, the exhaust duct is generally in a negative pressure state to prevent the backflow of toxic gases.

[0053] like Figure 1 and 3 As shown, as an embodiment, one of the sides of the box body 2 is provided with an opening 21; the transfer vehicle also includes a door body 4, which is arranged in the chamber, located at the position of the opening 21, and is sealed with the opening 21; the door body 4 can be moved in the horizontal direction relative to the box body 2 to open the opening 21, and the opening 21 is used to dock with the machine in the preparation of solid-state batteries. In this way, when the transfer vehicle is transferred to the machine, the door body 4 is moved and the opening 21 is opened, so that the machine can dock with the transfer vehicle, and the battery components of the solid-state battery in the box body 2 are taken out to proceed to the next step.

[0054] Optionally, the opening 21 faces the front side of the box 2, which facilitates docking with the machine.

[0055] Optionally, sealing rings can be provided on both sides of the opening 21. The sealing ring located inside the chamber can form a sealed connection with the door body 4 when the door body 4 is closed. The sealing ring located outside can form a sealed connection between the box body 2 and the machine when the box body 2 is docked with the machine, thereby avoiding leakage of toxic gases during transportation.

[0056] Optionally, the machine mentioned in the embodiment of the present application may include mid-end equipment, such as a stacking machine. When the transfer vehicle is transporting positive electrode sheets or negative electrode sheets bonded to hydrogen sulfide solid electrolyte membranes, the transfer vehicle needs to be pushed to the position of the stacking machine, docked with the stacking machine, and the next stacking process is carried out; the machine may also include back-end equipment, such as packaging equipment. When the transfer vehicle is transporting bare battery cells after hydrogen sulfide solid electrolyte membranes are bonded to positive electrode sheets and negative electrode sheets respectively, the transfer vehicle needs to be pushed to the position of the packaging equipment, docked with the packaging equipment, and the next packaging process is carried out.

[0057] like Figure 5 As shown, as an embodiment, an air intake pipe 5 is provided on one side of the box body 2, and the positions where the air intake pipe 5 and the exhaust pipe 3 are connected to the box body 2 are sealed. The air intake pipe 5 and the exhaust pipe 3 are both provided with a valve body. By setting the valve body, the air intake pipe 5 and the exhaust pipe 3 can be opened and closed; the air intake pipe 5 is used to introduce inert gas after the battery assembly of the solid-state battery is installed. The introduction of inert gas can limit the volatilization of toxic gases.

[0058] Optionally, the connection position between the intake pipe 5 and the box body 2 can be connected by a flange, which includes two flange plates, which are fixed on the exhaust pipe 3 and the box body 2 respectively, and then a sealing gasket is placed between the two flange plates, and they are tightly connected together with bolts to achieve sealing and fixation.

[0059] like Figure 3 、 5 As shown in FIG7 , as an embodiment, a slide 6 is further provided in the box body 2, and a rolling assembly 7 is provided on the door body 4. The door body 4 can slide relative to the slide 6 through the rolling assembly 7. By providing the slide 6 and the rolling assembly 7, the movement of the door body 4 is facilitated.

[0060] like Figure 7 As shown, optionally, two slideways 6 are provided, one above the other, and the two slideways 6 are connected to the upper top surface and the bottom plate of the box body 2 respectively.

[0061] like Figure 3 As shown, as an embodiment, the rolling assembly 7 includes a first connecting member 71 perpendicular to the door body 4 and a second connecting member 72 parallel to the door body 4. The rolling assembly 7 also includes rollers 73 provided on the first connecting member 71 and the second connecting member 72; the roller 73 is provided on at least one end of the first connecting member 71, and one end of the second connecting member 72 is connected to the door body 4, and the other end is provided with the roller 73. By providing the first connecting member 71 perpendicular to the door body 4 and the second connecting member 72 parallel to the door body 4, the two rollers 73 on the two connecting members can respectively support the door body 4 in the vertical and horizontal directions, thereby improving the smoothness of the movement of the door body 4. At the same time, it can also achieve torque balance between the first connecting member 71 and the second connecting member 72 to avoid stress concentration.

[0062] Optionally, two second connectors 72 can be provided on each of the upper and lower sides of the door body 4. Rollers 73 can be provided at both ends of the second connector 72, or a roller 73 can be provided at one end, and a roller 73 can be provided at the opposite end of the other second connector 72 on the same side.

[0063] As Figure 5 shown, as an implementation manner, a chute is provided in the slideway 6, and the rolling assembly 7 can slide along the chute. The chute includes a first groove 61 and a second groove 62 that communicate with each other. The first groove 61 and the second groove 62 are on different axes. The second groove 62 is located at the position where the door body 4 is closed and is close to the opening 21; the roller 73 on the second connector 72 is located in the chute. In this way, when the door body 4 is closed, since the second groove 62 is arranged close to the door body 4, during the closing process of the door body 4, it is buckled towards the opening 21 to the position of the opening 21, rather than always closing along the direction of the first groove 61. This is because a sealing ring is provided at the position of the opening 21. If the door body 4 directly closes from the side along the direction of the first groove 61, it is easy to hit the sealing ring during the closing process, and the sealing will fail after long-term use.

[0064] Optionally, the first groove 61 and the second groove 62 are connected by an inclined groove.

[0065] As Figure 7 shown, optionally, the embodiments of the present application are provided with two upper and lower slideways 6, and at least two chutes are provided in each slideway 6, which can improve the stability of the door body 4 during the moving process and also improve the smoothness of the opening movement.

[0066] Optionally, the door body 4 of the embodiments of the present application is a double-layer door body, and the fasteners can sequentially connect the double-layer door body of the embodiments of the present application.

[0067] Optionally, the rolling assembly 7 can include a plurality of first connectors 71 perpendicular to the door body 4 and second connectors 72 parallel to the door body 4. The rollers 73 on the first connectors 71 can slide along the surface of the slideway 6, and the rollers 73 on the second connectors 72 are located in the chute and move along the chute; by providing the first connectors 71 and rollers 73 perpendicular to the door body 4, it can play a supporting role in the direction perpendicular to the moving direction of the door body 4; by providing the second connectors 72 and rollers 73 parallel to the door body 4, it can play a guiding role when the door body 4 moves.

[0068] Optionally, at least one handle is provided on one side of the box body 2. The handle can pull the door body 4 to move relative to the box body 2. As a preferred implementation manner, two handles are provided in the embodiments of the present application. At the same time, the door body 4 of the present application is a double-layer structure, and each layer is connected to one handle. In this way, when one handle is damaged, the opening and closing function of the door body 4 can be realized through the other handle, so as to improve the adaptability of the product.

[0069] As Figure 2 and 4 shown, as an implementation manner, a moving mechanism 8 is further provided in the box body 2. The moving mechanism 8 is used to support the battery assembly of the solid-state battery. That is to say, the positive electrode plate and / or the negative electrode plate with a hydrogen sulfide solid electrolyte membrane, as well as the unencapsulated bare battery cell, can be placed on the moving mechanism 8, and the moving mechanism 8 can move relative to the box body 2 to align the battery assembly of the solid-state battery with the opening 21. In this way, after the opening 21 corresponds to the machine table, the door body 4 is opened, and through the movement of the moving mechanism 8, the battery assembly is aligned with the opening 21, and then the manipulator on the machine table can pull out the battery assembly from the box body 2, so as to perform the next process. In addition, by providing the moving mechanism 8, multiple groups of battery assemblies can also be placed on the support plate 85, increasing the number of battery assemblies accommodated in the box body 2. After one group of battery assemblies is pulled out of the box body 2 by the manipulator, the moving mechanism 8 can move to align another group of battery assemblies with the opening 21, ready to be pulled out by the manipulator.

[0070] Optionally, the manipulator can be a manipulator in the prior art, which can extend into the box body 2 through the opening 21 and then pull out the battery assembly from the box body 2. Those skilled in the art can make corresponding selections according to actual needs, and the present application will not introduce too much.

[0071] As Figure 4 shown, as an implementation manner, the moving mechanism 8 includes a rotatable rod 81. One end of the rotatable rod 81 is provided with a gear 82. The rotatable rod 81 passes through the box body 2 and is hermetically connected to the box body 2. The moving mechanism 8 further includes a support plate 85 and a rack 83. The rack 83 is fixed on the support plate 85. The support plate 85 is used to support the battery assembly of the solid-state battery. The rack 83 meshes with the gear 82. When the rotatable rod 81 rotates, the gear 82 will drive the rack 83 to move. When the rack 83 moves, it will also drive the support plate 85 to move, thereby realizing the movement of the drive battery assembly and making the battery assemblies of multiple groups of solid-state batteries on the support plate 85 respectively correspond to the position of the opening 21.

[0072] Optionally, at least two groups of battery assemblies can be placed on the support plate 85, and the battery assemblies of the same group are stacked.

[0073] Optionally, the rotatable rod 81 and the box body 2 can be connected by a flange.

[0074] Optionally, a hand crank is further provided at one end of the rotatable rod 81. By driving the rotation of the hand crank, it is convenient to drive the rotation of the rotatable rod 81.

[0075] As Figure 6 shown, as an implementation manner, a support platform 9 is further provided on the bottom plate of the box body 2. The rotatable rod 81 passes through the support platform 9, and the rotatable rod 81 is connected to the support platform 9 through a bearing assembly. By providing the support platform 9, stable support can be provided for the rotatable rod 81. At the same time, the rotatable rod 81 and the support platform 9 are connected through a bearing assembly, making the rotation of the rotatable rod 81 smoother.

[0076] As Figure 4 shown, as an implementation manner, the moving mechanism 8 further includes at least one slide rail assembly 84. The slide rail assembly 84 includes a slide rail and a slider. The slide rail is fixed on the bottom plate of the box body 2, and the support plate 85 is provided with a slider facing the direction of the slide rail. The slider can slide along the slide rail. By providing the slide rail and the slider, it is easier for the support plate 85 to rotate after being driven by the rotatable rod 81.

[0077] Optionally, there are two slide rail assemblies 84.

[0078] Optionally, the rack 83 is in the same direction as the extension direction of the slide rail, and at the same time, both of them are in the same direction as the opening and closing direction of the door body 4. In this way, it is convenient for the battery assembly of the solid-state battery on the support plate 85 to be aligned with the opening 21.

[0079] As Figure 6 shown, as an implementation manner, the transfer vehicle further includes a support frame 10. The support frame 10 can move relative to the support plate 85 along a direction perpendicular to the opening 21. The support frame 10 is used to place the battery assembly of the solid-state battery. In this way, when the box body 2 is docked with the machine table, the manipulator on the machine table can pull out the battery assembly of the solid-state battery placed on the support frame 10 from the opening 21 by pulling the support frame 10.
