Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing, in particular to a novel hot pressing mechanism device for a power battery side plate. Background Technique

[0002] With the rapid development of the new energy vehicle industry, as a core component of new energy vehicles, the performance and safety of power batteries have received increasing attention. As a key component of power batteries, the power battery side plate not only needs to have good mechanical strength, but also needs to be insulated at the part in contact with the battery cells to ensure the overall performance and safety of the battery. At present, in the manufacturing process of power battery side plates, hot pressing technology is widely used to hot press an insulating film on the side plates to meet the insulation requirements.

[0003] In the prior art, the hot pressing equipment for power battery side plates generally adopts the method of placing the side plates inside the equipment for hot pressing. Although this design can achieve the basic hot pressing function, during long-term use, a large amount of heat is likely to accumulate inside the equipment, resulting in overheating of the equipment, affecting the stability and service life of the equipment. At the same time, since the side plates need to be frequently taken and placed during the hot pressing process, operators face the risk of being scalded when taking and placing the side plates, increasing the safety hazards of the operation. Therefore, a novel hot pressing mechanism device for power battery side plates is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art that during long-term use, a large amount of heat is likely to accumulate inside the equipment, resulting in overheating of the equipment, affecting the stability and service life of the equipment. At the same time, since the side plates need to be frequently taken and placed during the hot pressing process, operators face the risk of being scalded when taking and placing the side plates, increasing the safety hazards of the operation, and a novel hot pressing mechanism device for power battery side plates is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A novel hot pressing mechanism device for a power battery side plate, including a base. On one side of the top of the base, two slide rails and a support frame are respectively fixedly connected. Slide grooves three are opened on both inner walls of the support frame. A plurality of slide rods are fixedly connected between the top outer walls of the two slide rails and the top inner wall of the support frame. The outer circumferential walls of the plurality of slide rods are slidably connected with the same upper pressing plate. A hot pressing plate is fixedly connected to the bottom of the upper pressing plate. Through slide grooves one and two are respectively opened on one side of the slide rails. A lower pressing plate is slidably arranged between the two slide rails. A connecting frame is fixedly connected to one side of the lower pressing plate. On the other side of the top of the base, a mounting plate is fixedly connected. A hydraulic cylinder is fixedly connected to one side of the mounting plate. A connecting mechanism for connection and transmission is arranged between the upper pressing plate and the hydraulic cylinder.

[0007] In a possible design, the connecting mechanism includes a connecting block and two first connecting shafts. One end of each of the two first connecting shafts is fixedly connected to both sides of the upper pressing plate. The end of the first connecting shaft away from the upper pressing plate is slidably connected in the third chute. The connecting block is fixedly connected to one end of the piston rod of the hydraulic cylinder. Both sides of the connecting block are fixedly connected with second connecting shafts. The second connecting shafts slidably penetrate through the second chutes on the same side. A same connecting rod is rotatably connected between the circumferential outer wall of the second connecting shaft and the circumferential outer wall of the first connecting shaft on the same side.

[0008] In a possible design, a groove is formed on one side of the connecting block. A same tension spring is fixedly connected between the inner wall of one side of the groove and one side of the connecting frame.

[0009] In a possible design, a through hole is formed in the top of the lower pressing plate. A placing plate is slidably connected in the through hole. A receiving groove is formed in the top of the base. A resisting block is slidably connected in the receiving groove. Bevels for contacting the lower pressing plate are formed on both sides of the top of the resisting block. A same spring is fixedly connected between the bottom of the resisting block and the inner wall of the bottom of the receiving groove.

[0010] In a possible design, first limiting blocks for supporting and restricting the position of the placing plate are fixedly connected to the bottoms of the inner walls on both sides of the through hole formed in the top of the lower pressing plate. Second limiting blocks are fixedly connected to the outer walls around the resisting block. Limiting protrusions are arranged on the tops of the inner walls around the receiving groove formed in the top of the base. The second limiting blocks are adapted to the limiting protrusions to prevent the resisting block from detaching from the base.

[0011] In a possible design, sliding blocks are fixedly connected to both sides of the lower pressing plate and the connecting frame. The two sliding blocks on the same side are respectively slidably connected in the corresponding first chute and second chute. The length of the first chute is shorter than that of the second chute.

[0012] In this application, when people use this device to hot-press the side plate of a power battery, first place the side plate of the power battery to be hot-pressed on the placement plate, then start the hydraulic cylinder. Then, the piston rod of the hydraulic cylinder contracts inward and drives the connecting block, and then pulls the connecting frame and the lower pressing plate inward through the tension spring. At the same time, the connecting block drives the connecting rod through the second connecting shaft, and then drives the upper pressing plate and the hot pressing plate to move downward along the sliding rod through the first connecting shaft. When the lower pressing plate moves to directly below the hot pressing plate, the first chute blocks the lower pressing plate from continuing to move inward by restricting the slider sliding inside, while the upper pressing plate and the hot pressing plate continue to hot-press the side plate of the power battery to be hot-pressed placed on the placement plate under the drive of the piston rod of the hydraulic cylinder. When the hot pressing is completed, the piston rod of the hydraulic cylinder extends outward and drives the upper pressing plate and the hot pressing plate to move upward, while pushing the connecting block outward. At this time, due to the pulling of the tension spring and the restriction of the first chute, the lower pressing plate still remains directly below the hot pressing plate. When the connecting block contacts the connecting frame, the connecting block pushes the connecting frame and then pushes the lower pressing plate outward. When the lower pressing plate contacts the abutting block, the lower pressing plate presses the abutting block inward through the inclined surface opened on one side of the top of the abutting block. When the abutting block is located in the through hole opened on the top of the lower pressing plate, it slowly rises under the dual action of the elastic force of the spring and the inclined surface opened on the other side of the top of the abutting block, and slowly pushes out the placement plate, and then drives the hot-pressed side plate of the power battery to separate from the lower pressing plate, facilitating people to take it.

[0013] In this utility model, for the novel hot-pressing mechanism device of the side plate of a power battery, through the setting of the support frame and the connecting mechanism, the hot pressing plate can complete the hot pressing operation in the external environment, effectively solving the problem of overheating caused by heat accumulation during long-term use inside the equipment, thereby improving the stability and overall service life of the device;

[0014] In this utility model, for the novel hot-pressing mechanism device of the side plate of a power battery, through the setting of the placement plate, the connecting frame and the abutting block, the hydraulic cylinder can be used to push the side plate out to the outside after hot pressing is completed, and the abutting block is used to separate the side plate on the placement plate from the lower pressing plate, avoiding the contact between the operator and the equipment when placing and taking the side plate, greatly reducing the risk of scalding and improving the safety of operation;

[0022] Embodiment 1

[0023] Refer to Figures 1 - 4, A hot pressing mechanism device, including a base 1. On one side of the top of the base 1, two slide rails 4 and a support frame 7 are fixedly connected by bolts or other fastening means. Slide grooves three 16 are machined on the inner walls of both sides of the support frame 7 for the sliding connection of subsequent components. Between the outer walls of the tops of the two slide rails 4 and the inner wall of the top of the support frame 7, a plurality of parallel slide rods 15 are connected by welding or fasteners. These slide rods 15 jointly support and guide the sliding of an upper pressing plate 5. The bottom of the upper pressing plate 5 is fixedly connected with a hot pressing plate 6 by bolts or welding for hot pressing the side plate of the power battery. On one side of the slide rail 4, through grooves one 11 and through grooves two 12 are respectively opened. These two through grooves are used to guide the sliding of the lower pressing plate 2 and its connecting components. The lower pressing plate 2 cooperates with the through grooves one 11 and through grooves two 12 to slide through the connecting frames 13 fixedly connected to its two sides. On the other side of the top of the base 1, a mounting plate 8 is fixedly connected. A hydraulic cylinder 9 is fixed on the mounting plate 8 by bolts. The piston rod of the hydraulic cylinder 9 is connected to the upper pressing plate 5 through a set of connecting mechanisms to achieve power transmission. The connecting mechanism specifically includes a connecting block 14. The two sides of it respectively slide through a connecting shaft two 18 in the through groove two 12. The other end of the connecting shaft two 18 is rotationally connected to a connecting shaft one 17 fixed on both sides of the upper pressing plate 5 through a connecting rod 10. The other end of the connecting shaft one 17 is slidably connected in the slide groove three 16 of the support frame 7 to ensure the stable movement of the upper pressing plate 5 in the vertical direction;

[0024] A groove is opened on one side of the connecting block 14, and a tension spring 20 is fixedly connected between the inner wall of one side of the groove and one side of the connecting frame 13. The setting of the tension spring 20 helps to maintain a certain distance between the upper pressing plate 5 and the lower pressing plate 2 in the non-working state of the hydraulic cylinder 9, and at the same time increases the reset stability and reliability of the whole device. In order to further improve the positioning accuracy and stability of the side plate of the power battery during the hot pressing process, in this embodiment, the lower pressing plate 2 and its related components are improved. A through hole is opened on the top of the lower pressing plate 2, and a placing plate 3 is slidably connected in the through hole for placing the battery side plate to be hot pressed. A receiving groove is opened on the top of the base 1, and a pressing block 22 is slidably connected in the receiving groove. Bevels are provided on both sides of the top of the pressing block 22. A spring 24 is connected between the bottom of the pressing block 22 and the inner wall of the bottom of the receiving groove to provide necessary buffering and reset force. In addition, limiting blocks one 21 are fixedly connected to the bottoms of the inner walls on both sides of the through hole opened on the top of the lower pressing plate 2 to support and limit the position of the placing plate 3 to prevent it from shifting during the hot pressing process. Limiting blocks two 23 are fixedly connected to the bottom of the outer wall around the pressing block 22, and limiting protrusions 25 are provided on the top of the inner walls around the receiving groove opened on the top of the base 1. The limiting blocks two 23 are adapted to the limiting protrusions 25 to prevent the pressing block 22 from completely detaching from the base 1 under the action of the spring 24.

These sliders 19 are respectively slidably connected in the corresponding first chute 11 and second chute 12. It should be noted that the length of the first chute 11 is designed to be shorter than that of the second chute 12 to ensure that during the hot pressing process, the lower pressing plate 2 can first move to directly below the hot pressing plate 6, and then the hot pressing plate 6 continues to descend for the hot pressing operation.

[0028] However, as is well known to those skilled in the art, the working principles and wiring methods of the hot pressing plate 6 and the hydraulic cylinder 9 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here.
