[0023] Based on the background technology, the traditional laminating machine for manufacturing battery pack insulation plates usually has only one laminating station, which is difficult to meet the processing of insulation plates of different sizes and has certain limitations. The utility model provides a battery pack insulation plate laminating device, which aims to configure a first laminating station 11 and a second laminating station 12 on a frame 1, and the first laminating station 11 and the second laminating station 12 are both equipped with an upper mold base 2 and a lower pressing component for driving the upper mold base 2 to move, and the size of the lower mold base 3 can be selectively configured on the frame 1. By controlling the size of the lower mold base 3, the present application can realize the processing and forming of battery pack insulation plates of different sizes, thereby improving the processing range of the present application for battery pack insulation plates and improving the scope of application of the present application.

[0024] like Figures 1 to 3 As shown, the battery pack insulation plate laminating equipment of the utility model comprises: a frame 1, on which a first laminating station 11 and a second laminating station 12 are formed; an upper mold base 2, which has two and is respectively arranged at the first laminating station 11 and the second laminating station 12, and the upper mold base 2 is driven by the lower pressing component to move in the vertical direction; a lower mold base 3, which is detachably arranged on the frame 1 at the first laminating station 11 and / or the second laminating station 12 and is placed below the upper mold base 2.

[0025] See also Figure 1 , Figure 2 The first laminating station 11 and the second laminating station 12 are both equipped with an upper die base 2 and a lower pressing assembly. The lower die base 3 is detachably arranged on the frame 1 and is located directly below the first laminating station 11 or the second laminating station 12 .

[0026] When the upper mold base 2 and the lower mold base 3 are molded together, the insulating plate located between the two can be hot-pressed. When there is only one lower mold base 3, hot-pressing processing of smaller-sized battery pack insulating plates can be realized. When processing of larger-sized battery pack insulating plates is required, the smaller lower mold base 3 can be removed, and then the lower mold base 3 that can be located at the first laminating station 11 and the second laminating station 12 at the same time can be installed; through this arrangement, the processing range of the battery pack insulating plate of the present application can be effectively improved, and the scope of application of the present application can be improved.

[0027] In a possible embodiment, a linear module is arranged on the frame 1, and the lower die base 3 is detachably mounted on the linear module via a tray. This arrangement facilitates the movement of the lower die base 3 on the frame 1, thereby facilitating the blanking of the formed battery pack insulation board.

[0028] In one or more embodiments, the pressing assembly at least includes a first driving device 41 disposed above the frame 1 and a supporting plate 42 driven by the first driving device 41 ; wherein the upper mold base 2 is disposed at the bottom of the supporting plate 42 .

[0029] See also Figure 1 , Figure 2 , Figure 3 The first driving device 41 can be a driving cylinder, which drives the supporting plate 42 to move downward, thereby realizing the upper mold base 2 approaching the lower mold base 3 to realize the mold closing operation, which has the characteristics of convenient operation and simple structure.

[0030] In one or more embodiments, it also includes a lifting mechanism arranged on the frame 1 below the lower mold base 3, and the lifting mechanism is used to drive the lower mold base 3 located at the first film pressing station 11 and / or the second film pressing station 12 to move in the vertical direction; the lifting mechanism at least includes a second driving device 51 arranged on the frame 1 and a push rod 54 driven to rise by the second driving device 51; wherein the push rod 54 can pass through the frame 1 upward and abut against the bottom surface of the lower mold base 3; there are two push rods 54 and they are respectively located at the first film pressing station 11 and the second film pressing station 12.

[0031] See also Figure 1 , Figure 2The second driving device 51 can be a servo motor, and two push rods 54 are installed on the bottom plate 52. The bottom plate 52 has a threaded hole. The shaft end of the second driving device 51 is equipped with a screw 53. The screw 53 is driven to rotate by the second driving device 51, so that the bottom plate 52 moves up and down to get close to or away from the lower mold base 3, and then the push rod 54 lifts the lower mold base 3, so that the upper mold base 2 and the lower mold base 3 move toward each other, which speeds up the production efficiency of the battery pack insulation board and has practicality. In addition, by connecting the screw 53 and the bottom plate 52 by thread, the accuracy of the push rod 54 in controlling the rising height of the lower mold base 3 can be improved, thereby improving the use effect of the present application.

[0032] It should be noted that the two push rods 54 are respectively located at the first film laminating station 11 and the second film laminating station 12. When the push rods 54 control the two push rods 54 to rise, the two push rods 54 extend out of the frame 1 at the same time and contact the lower mold base 3 at the first film laminating station 11 or the second film laminating station 12, thereby realizing the lifting of the lower mold base 3.

[0033] In other possible implementations, the second driving device 51 may be a driving cylinder, which directly controls the push rod 54 to lift the lower mold base 3, which has the characteristics of convenient operation and simple structure.

[0034] In one or more embodiments, the push rod 54 is formed with a friction force expansion portion at one end close to the lower die base 3. The diameter of the friction force expansion portion is larger than the diameter of the push rod 54, and the shape of the friction force expansion portion can be disc-shaped, triangular-shaped, etc.; through this arrangement, the stability of the push rod 54 when lifting the lower die base 3 can be improved.

[0035] In one or more embodiments, a limiting component is disposed between the first laminating station 11 and the second laminating station 12, and at a position of the second laminating station 12 away from the first laminating station 11. The limiting component is used to limit the position of the lower mold base 3 disposed on the frame 1. The limiting component includes at least a third driving device 61 disposed on the frame 1 and a limiting block 62 that can be lifted by the third driving device 61 to be flush with the side of the upper mold base 2.

[0036] See also Figure 2 , Figure 3, when the lower mold base 3 is only located at the first laminating station 11, the third driving device 61 located between the first laminating station 11 and the second laminating station 12 is controlled to work so that the limit block 62 rises to form a limit on the side of the lower mold base 3, thereby improving the accuracy of the position of the lower mold base 3; when the volume of the lower mold base 3 increases and is relatively located at the first laminating station 11 and the second laminating station 12, the third driving device 61 at the second laminating station 12 away from the first laminating station 11 controls the limit block 62 to extend, thereby limiting the side position of the lower mold base 3, further improving the accuracy of the position of the lower mold base 3, and improving the molding effect of the battery pack insulation plate. It should be noted that the third driving device 61 can be a driving cylinder.

It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
