Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a constant-temperature, multi-specification, and highly compatible restraint battery device. Background Art

[0002] During the formation and static process of new batteries, the batteries need to be restrained and fixed and cooperate with temperature-raising and temperature-control operations. Traditional restraint devices and temperature-raising and temperature-control devices are usually designed separately, and the batteries need to be transferred separately to independent temperature-raising and temperature-control devices (such as constant temperature storage locations) for reloading. This process involves multiple loading and unloading operations, which increases labor costs and time costs. At the same time, the batteries are easily damaged by bumps and collisions due to frequent transportation, affecting product yield. In addition, since the temperature-raising and temperature-control devices are separated from the restraint devices, the batteries will experience heat loss during the transfer process, resulting in an extension of the overall temperature-raising and temperature-control time, thereby affecting battery production efficiency, which needs to be solved urgently.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0017] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0018] Please refer to the following Figure 1 To the attached Figure 6 The present invention describes a constant temperature, multi-specification, and highly compatible restraint battery device.

[0019] Reference Figures 1 to 6 The constant temperature multi-specification and highly compatible restraint battery device includes a restraint frame 1 and a restraint device 2. A plurality of restraint partitions 3 are arranged and slide inside the restraint frame 1. Specifically, fixed shafts 4 are fixedly installed on the top and bottom of the restraint frame 1. The top and bottom sides of the restraint frame 1 are slidably connected to the fixed shaft 4 to improve the sliding connection stability of the restraint frame 1. A restraint heating channel for placing batteries is formed between two adjacent restraint partitions 3. Heating plates 5 and first thermally conductive silicone rubber 6 are sequentially provided on the opposite sides of the restraint partition 3. The restraint device 2 is provided on the restraint frame 1 and is used to drive the first restraint partition 3 to move toward the adjacent restraint partition 3. The heating plate 5 and the abutment restraint function are integrated in the restraint partition 3 to realize the integration of restraint and heating, avoid battery transfer, shorten the heating time, and the heating plate 5 is in close contact with the battery through the first thermally conductive silicone rubber 6, which can improve the heat transfer efficiency.

[0020] It should be noted that the heating plate 5 can adopt the commonly used methods on the market such as embedded resistance wire, laminated heating film, built-in PTC heating plate, etc. to achieve the function of heating the board surface. This is common knowledge among those skilled in the art and will not be elaborated or specifically limited here.

[0021] Preferably, two opposite mounting side panels 7 are provided between each two adjacent restraint partitions 3, and a second thermally conductive silicone rubber 8 is provided on the inner side of the mounting side panel 7. Splicing grooves 9 and buckles 11 are provided on opposite sides of the restraint partition 3. The opposite side walls of the splicing grooves 9 are open, and the positions of the mounting side panels 7 corresponding to the splicing grooves 9 are provided with splicing blocks 10 for plugging into the splicing grooves 9. The splicing blocks 10 include a sliding portion 101 and a limiting portion 102. When the splicing blocks 10 are plugged into the splicing grooves 9, the sliding portion 101 slides into the inside of the splicing grooves 9 through the side wall opening of the splicing grooves 9, the limiting portion 102 is used to abut the inner side wall of the splicing grooves 9, and the buckle 11 is used to abut the outer side of the mounting side panel 7. By providing the mounting side panel 7, it can be directly engaged during restraint. It contacts the side of the battery and efficiently transfers the heat of the first thermally conductive silicone 6 of the restraint partition 3 to the side of the battery through the second thermally conductive silicone 8 of the installation side panel 7, thereby realizing the synchronous heating function around the battery. At the same time, the installation side panel 7 is locked with the splicing groove 9 of the restraint partition 3 through the sliding part 101 and the limiting part 102 of the splicing block 10, and is fixed with the buckle 11, so as to form a stable support structure and a quick disassembly structure to enhance the stability and convenience of the restraint. Specifically, during installation, the sliding part 101 slides into the side wall opening of the splicing groove 9, and the limiting part 102 abuts against the inner wall of the groove after being in place to realize lateral limitation. The buckle 11 presses the installation side panel 7 from the outside to prevent longitudinal loosening. When disassembly is required, release the buckle 11 and take out the installation side panel 7 from the longitudinal direction.

[0022] It should be noted that, in actual work, the width of the restrained temperature-raising channel can be adjusted simply by replacing the mounting side plates 7 with different widths, so as to achieve compatibility with batteries of different sizes.

[0023] Furthermore, a side abutment plate 12 is provided on the inner side of the mounting side plate 7, and the side abutment plate 12 is slidably connected to the inner side of the mounting side plate 7 through a guide rod 13. A spring 14 is fixedly connected between the side abutment plate 12 and the mounting side plate 7, and the second thermally conductive silicone rubber 8 is provided on a side of the side abutment plate 12 away from the mounting side plate 7, wherein the side abutment plate 12 driven by the guide rod 13 and the spring 14 is provided on the inner side of the mounting side plate 7, and the second thermally conductive silicone rubber 8 on its surface is tightly attached to the side of the battery under the elastic force of the spring 14, and the elastic force of the spring 14 compensates for the size deviation and deformation of the battery, so that the second thermally conductive silicone rubber 8 is in gapless contact with the battery surface, thereby improving the heat transfer efficiency.

[0024] Preferably, the constant temperature restraint battery device with multiple specifications and strong compatibility also includes a number of support seats 15, which are all slidably arranged on the restraint frame 1 and are used to provide support for the battery. A number of restraint partitions 3 and a number of support seats 15 are spaced apart in the order of restraint partitions 3 and support seats 15. A constant temperature cavity for accommodating the battery is formed between two adjacent restraint partitions 3, support seats 15 and two opposite mounting side panels 7. Among them, the support seats 15 and the restraint partitions 3 are spaced apart and cooperated with the mounting side panels 7 to form a constant temperature cavity, which provides bottom support for the battery and reduces heat loss.

[0025] Specifically, the support seat 15 includes a guide rail slide 151, which is slidably connected to the restraint frame 1. Two opposing battery insulation pads 152 are detachably provided on the top of the guide rail slide 151. A clearance channel is left between the two battery insulation pads 152 for the installation side panel 7 to pass through. A battery replacement pad 153 for supporting the battery is detachably provided on the top of the battery insulation pad 152. Among them, the guide rail slide 151, the detachable battery insulation pad 152 and the replacement pad combination of the support seat 15 achieve compatibility in the height direction of the battery. During operation, the height of the support seat 15 can be adjusted by replacing pads of different thicknesses to adapt to batteries of different heights. The guide rail slide 151 ensures that the support seat 15 is accurately positioned, and the clearance channel ensures that the support seat 15 will not interfere with the installation side panel 7.

[0026] Furthermore, a plurality of rollers 154 are arranged on the top of the battery replacement pad 153. By arranging the rollers 154 on the top of the battery replacement pad 153, the friction during the loading and unloading of the battery can be reduced, thereby overcoming the problem of inconvenient operation due to the heavy battery.

[0027] Preferably, temperature detectors 16 are provided on two opposite sides of the restraint partition 3, and the temperature detectors 16 are controlled and connected to the heating plate 5. By arranging temperature detectors 16 on both sides of the restraint partition 3 and controlling the heating plate 5, temperature closed-loop control can be achieved. During operation, the probes monitor the surface temperature of the battery in real time, and feed back to the control system to adjust the heating power, maintain a constant temperature or heat within a certain temperature, avoid overheating or insufficient temperature, and ensure the stability of the battery formation and static process.

[0028] In addition, in this embodiment, the restraint device 2 includes an upper trapezoidal screw rod 21 and a lower trapezoidal screw rod 22. One end of the upper trapezoidal screw rod 21 is threaded through the restraint frame 1 and is fixedly connected to the pressure handwheel 23. The other end of the upper trapezoidal screw rod 21 is rotatably connected to the first restraint partition 3. A section of the lower trapezoidal screw rod 22 is threaded through the restraint frame 1 and the other end is rotatably connected to the first restraint partition 3. The upper trapezoidal screw rod 21 and the lower trapezoidal screw rod 22 are both coaxially fixedly connected to a synchronous wheel 24. A synchronous toothed belt 25 is wound and meshed between the two synchronous gears. During operation, the upper and lower trapezoidal screw rods 22 of the restraint device 2 are driven by the synchronous wheel 24 and the synchronous toothed belt 25 to ensure that the upper and lower trapezoidal screw rods 22 move forward synchronously, so that the restraint partition 3 applies uniform lateral restraint force to the battery, ensuring consistent heat transfer in various parts of the battery and improving product quality.

[0029] The implementation principle of a constant temperature, multi-specification, and highly compatible restraint battery device in the embodiment of the present application is as follows: by arranging a restraint partition 3 with a heating plate 5 and a first thermally conductive silicone rubber 6 in a restraint frame 1, and utilizing an upper trapezoidal screw 21 and a lower trapezoidal screw 22 to drive the first restraint partition 3 to move via a synchronous wheel 24 and a synchronous toothed belt 25, so that the batteries in the restraint heating channel formed between adjacent restraint partitions 3 are evenly compressed, thereby heating the batteries in all restraint heating channels. At the same time, the restraint partition 3 can be matched with an installation side panel 7 through the plug-in cooperation of the splicing block 10 and the splicing groove 9 and the snap fastener 11 for fixation, and a side abutment plate with a second thermally conductive silicone rubber 8 is installed on the inner side of the installation side panel 7. 12 is elastically pressed against the side of the battery by the spring 14 and the guide rod 13, completing the multi-directional restraint of the battery, realizing the simultaneous completion of the battery restraint and heating processes, improving the production efficiency of the product, and cooperating with the detachable battery insulation pad 152 on the support seat 15 and the changeable pad with roller 154, realizing convenient loading and multi-specification adaptation of the battery, and the device has strong compatibility, and the temperature detector 16 monitors and controls the temperature of the heating plate 5 in real time. The constant temperature wall formed by the restraint partition 3, the support seat 15 and the installation side plate 7 can reduce heat loss, ensure that the battery is efficiently heated and easy to maintain a constant temperature in the restrained state, and realize the integrated design of the temperature control device and the restraint device 2.

[0030] The above specific embodiments do not constitute a limitation on the scope of protection of this application. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors.
