[0034] Specifically, please refer to Figures 1 to 3 , in order to ensure the integrity of the entire thermal lamination device 100 and the compactness of the layout, when setting the deviation rectifying device 30 in this embodiment, the deviation rectifying device 30 further includes a mounting seat 40, and the rotational deviation rectifying mechanism 32, the Y-direction deviation rectifying mechanism 33, and the X-direction deviation rectifying mechanism 34 are all mounted on the mounting seat 40.

In this way, through the installation of the Y-direction deviation rectifying mechanism 33 on the mounting frame 41, the electrode sheet 200 can pass through the mounting frame 41 and move towards the frame 10. By installing the rotational deviation rectifying mechanism 32 and the X-direction deviation rectifying mechanism 34 on the connecting frame 42 and driving the connecting frame 42 and the mounting frame 41 to rotate relative to each other under the drive of the rotational deviation rectifying mechanism 32, the angular adjustment of the position of the electrode sheet 200 on the mounting frame 41 can be realized, and the X-direction deviation rectifying mechanism 34 is used for driving the mounting frame 41 to move in the X direction to realize the adjustment of the position of the electrode sheet 200 in the X direction.

[0036] Among them, please refer toFigure 3 and Figure 4 , is a structural schematic diagram of the rotation correction mechanism 32 of an embodiment of the utility model, the rotation correction mechanism 32 includes a rotation driving member 321, a first arc guide member 322 and a second arc guide member 323, the rotation driving member 321 and the first arc guide member 322 are installed on the connecting frame 42, the second arc guide member 323 is installed on the mounting frame 41, and is slidably arranged relative to the first arc guide member 322, so that under the drive of the rotation driving member 321, the mounting frame 41 can rotate relative to the connecting frame 42. Specifically, the rotation driving member 321 of this embodiment is a rotary motor, when the rotary motor is started, the mounting frame 41 is driven to rotate relative to the connecting frame 42, so as to adjust the swing angle of the pole piece 200, so as to achieve the effect of more precise adjustment of the position of the pole piece 200.

[0037] Specifically, in this embodiment, the first arc-shaped guide member 322 is a slider, and the second arc-shaped guide member 323 is a slide groove, and the slide groove is provided to guide the movement of the mounting frame 41. In other embodiments, the first arc-shaped guide member 322 can also be a slide groove, and the second arc-shaped guide member 323 can be a slider, which can also achieve the effect of driving the mounting frame 41 to rotate.

[0038] See also Figure 2 and Figure 4 , is a structural schematic diagram of the X-direction correcting mechanism 34 of an embodiment of the utility model. Specifically, the X-direction correcting mechanism 34 includes an X-direction driving member 341, a driving electric cylinder of the X-direction correcting mechanism 34 of this embodiment, and a fixing frame 43 includes a fixing plate 431 and an adapter 432. The X-direction driving member 341 is connected between the adapter 432 and the connecting frame 42. The connecting frame 42 is slidably arranged relative to the fixing plate 431. Under the drive of the X-direction correcting mechanism 34, the connecting frame 42 can drive the mounting frame 41 to move along the X-direction together, so as to realize the adjustment of the X-direction position of the pole piece 200 penetrated on the mounting frame 41.

[0039] Specifically, when the connecting frame 42 is set to slide relative to the fixed plate 431, it is achieved through the guide rod 342, that is, the X-direction correction mechanism 34 also includes a guide rod 342, and the guide rod 342 is connected to the connecting frame 42 and is slidably set relative to the fixed plate 431. In this way, through the setting of the guide rod 342, when the connecting frame 42 moves along the X direction, it is guided by the guide rod 342, and the connecting frame 42 and the mounting frame 41 are supported by the guide rod 342, thereby ensuring the stability of the movement of the connecting frame 42 and the mounting frame 41.

[0040] Further, in order to ensure the smoothness of the movement of the connecting frame 42 and the mounting frame 41 in the X direction, the X-direction deviation rectifying mechanism 34 further includes a bearing 343. The bearing 343 is installed on the fixing plate 431 and is used for the guide rod 342 to slide. Specifically, the bearing 343 in this embodiment is a universal bearing. By setting the bearing, the smoothness of the movement of the connecting frame 42 and the mounting frame 41 relative to the fixing plate 431 through the guide rod 342 is ensured.

[0041] Among them, in order to ensure the stability of the movement of the connecting frame 42 and the mounting frame 41 in the X direction, the X-direction deviation rectifying mechanism 34 includes two guide rods 342 and two bearings 343. One guide rod 342 slides with one bearing 343. The connecting frame 42 is supported by the two guide rods 342 to prevent the gravity from concentrating on one guide rod 342.

[0042] Please refer to Figure 4 and Figure 5 In an embodiment of the present utility model, the Y-direction deviation rectifying mechanism 33 includes a Y-direction driving member 331, a driving roller 332, a lifting driving member 333, and a driven roller 334. The driving roller 332 is connected to the Y-direction driving member 331 and is driven to rotate by the Y-direction driving member 331; the driven roller 334 is connected to the lifting driving member 333 and is driven by the lifting driving member 333 to move up and down to cooperate with or move away from the driving roller 332. In this way, under the drive of the Y-direction driving member 331, the pole piece 200 is clamped by the driving roller 332 and the driven roller 334 and moves forward. When it is necessary to adjust the forward speed of the pole piece 200, it can be achieved by controlling the driving speed of the Y-direction driving member 331; when it is necessary to replace the pole piece 200, the driven roller 334 is lifted by controlling the lifting driving member 333, and the pole piece 200 can be conveniently and quickly passed through between the driving roller 332 and the driven roller 334.

[0043] Specifically, the lifting driving member 333 in this embodiment is a driving cylinder. Through the drive of the driving cylinder, the up and down movement of the driven roller 334 is driven to achieve cooperation or separation from the driving roller 332.

[0044] It can be understood that when the pole piece 200 and the separator 300 are thermally compounded, the pole piece 200 includes a positive pole piece and a negative pole piece. The positive pole piece and the negative pole piece are respectively placed on the opposite side surfaces of the separator 300. Therefore, the thermal compounding device 100 includes two deviation rectifying devices 30. One deviation rectifying device 30 is used to rectify the state of the positive pole piece, and the other deviation rectifying device 30 is used to rectify the state of the negative pole piece.

[0045] Please refer to Figure 1 and Figure 2, in an embodiment of the present utility model, the vision detection mechanism 31 includes two CCD cameras 311 that are separately arranged. When installing the two CCD cameras 311, the two CCD cameras 311 are separately arranged on the frame 10 along the width direction of the pole piece 200 to monitor the two side edges of the pole piece 200. Thus, the two CCD cameras 311 are used to monitor the two side edges of the pole piece 200 in the width direction to monitor whether the position of the pole piece 200 corresponds to that of the diaphragm 300. Compared with the method of only detecting the middle region of the pole piece 200, the accuracy of judgment is improved.

It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
