[0041] Embodiment 1

[0042] In this embodiment, a stacking center calibration device is proposed, which is used to calibrate the center line of a stack formed by stacking multiple bottom covers up and down; that is, it can make the upper bottom cover and the lower bottom cover stack vertically straight, so as to calibrate the center line of the stack into a vertical straight line, avoiding the collapse of the formed stack due to its too high height; and it does not require manual calibration, saving time and effort, with high work efficiency, and avoiding the inaccuracy of manual operation in accurately ensuring that the center line of the stack is calibrated into a vertical straight line, and its calibration accuracy is high.

[0043] Specifically, as Figure 1 shown, the stacking center calibration device includes a bracket 1, a first bracket and a second bracket (not shown in the figure) arranged oppositely, and at least two groups of calibration components 4; wherein, a first driving member 2 is arranged at the bottom end of the bracket 1, the first driving member 2 is drivingly connected to a bottom plate 3 for placing the bottom cover, and the center of the bottom cover coincides with the center of the bottom plate 3, which can ensure that the centers of the stacked bottom covers are basically coincident, that is, initially position the positions of the stacked bottom covers; the first bracket and the second bracket are both movably suspended above the bottom plate 3; multiple groups of calibration components 4 are all arranged on the bracket 1 and located on the outer periphery of the stack 5, and each group of calibration components 4 includes two rotatable members 41 arranged oppositely and two calibration rods 42 respectively swingably connected to the two rotatable members 41, the rotatable members 41 and the calibration rods 42 are both vertically arranged, and the length direction of the rotatable member 41 and the length direction of the calibration rod 42 coincide with the height direction of the stack 5.

[0044] Among them, the first driving member 2 is used to drive the bottom plate 3 to move vertically upward to move the bottom cover to the first bracket and the second bracket to form a stack 5, rotate the rotatable member 41 to drive the calibration rod 42 to swing and abut against the stack 5, so that each calibration rod 42 can mutually squeeze the stack 5 from the outer periphery of the stack 5, so that each bottom cover can be kept vertically straight, so as to calibrate the center line of the stack 5 into a vertical straight line. In this embodiment, the first driving member 2 is a lifting cylinder.

[0045] By placing the bottom cover on the bottom plate 3, the first driving member 2 is driven to move the bottom plate 3 vertically upward to move the bottom cover to the first bracket and the second bracket; and repeat the above steps to move the next bottom cover to the bottom end of the previous bottom cover and support it on the first bracket and the second bracket to form a stack 5; then rotate the rotatable member 41 to drive the calibration rod 42 to swing and abut against the stack 5, so that the calibration rod 42 can mutually squeeze the stack 5 from the outer periphery of the stack 5, so that the upper bottom cover and the lower bottom cover can be stacked vertically straight, so as to calibrate the center line of the stack 5 into a vertical straight line; there is no need for manual calibration anymore, saving time and effort, with high work efficiency, and automatically calibrating through the calibration rod 42, avoiding the inaccuracy of manual operation in accurately ensuring that the center line of the stack 5 is calibrated into a vertical straight line, and its calibration accuracy is high.

[0046] Further, each calibration component 4 further includes two connecting components. One connecting component is used to connect a rotating member 41 and a calibration rod 42, so that the rotating member 41 rotates, which can drive the connecting component to rotate, and then drive the calibration rod 42 to swing. Among them, as Figure 1 shown, each connecting component includes two connecting members 431. The two connecting members 431 are respectively located at the upper and lower ends of the calibration rod 42. One end of the connecting member 431 is fixedly inserted outside the rotating member 41, and the other end of the connecting member 431 is fixedly inserted through the end of the calibration rod 42. Thus, when the rotating member 41 rotates to drive the connecting member 431 to rotate, the connecting member 431 rotates to drive the calibration rod 42 to swing relative to the axis of the rotating member 41.

[0047] Specifically, as Figure 1 shown, the calibration component 4 further includes a second driving member 44. The second driving member 44 is arranged at the top of the bracket 1, and the second driving member 44 is respectively drivingly connected to the two rotating members 41. The second driving member 44 is used to drive the rotating members 41 to rotate. In this embodiment, the second driving member 44 is an electric cylinder.

[0048] Further, the calibration component 4 further includes an intermediate component. One end of the intermediate component is drivingly connected to the electric cylinder, and the other end of the intermediate component is respectively connected to the two rotating members 41. The electric cylinder drives the intermediate component to move, and the intermediate component moves to drive the rotating members 41 to rotate.

[0049] Specifically, as Figure 1 shown, the intermediate component includes a first intermediate member 451, a second intermediate member 452 and a third intermediate member 453. Among them, one end of the first intermediate member 451 is drivingly connected to the electric cylinder, and the other end of the first intermediate member 451 is fixedly sleeved on the end of one of the two rotating members 41. One end of the second intermediate member 452 is fixedly sleeved on the end of the other rotating member 41 among the two, the other end of the second intermediate member 452 is connected to one end of the third intermediate member 453, and the other end of the third intermediate member 453 is connected to the first intermediate member 451.

[0050] In this embodiment, the number of the calibration components 4 is two groups, so that the four calibration rods 42 in the two calibration components 4 can respectively squeeze the stack 5 from the four directions on the outer periphery of the stack 5, so that each bottom cover can be kept straight up and down, thereby calibrating the center line of the stack 5 into a vertical line. Setting two groups of calibration components 4 can ensure the calibration requirement of the center line of the stack 5 on the one hand, and the processing is simple on the other hand, and the structure of the entire stack center calibration device is relatively simple. In other embodiments, the number of the calibration components 4 can also be three groups or four groups.

[0051] Embodiment 2

[0052] In this embodiment, a stacking center calibration method based on the stacking center calibration device in Embodiment 1 is proposed, which can relatively accurately ensure that the center line of the stack is a vertical straight line, and the calibration operation is relatively simple and convenient. For example, Figure 2 as shown, it includes the following steps:

[0053] S1: Place the bottom cover on the bottom plate 3, and the center of the bottom cover coincides with the center of the bottom plate 3. Then, make the first driving member 2 drive the bottom plate 3 to move vertically upward to move the bottom cover onto the first bracket and the second bracket;

[0054] S2: Repeat step S1 to move the next bottom cover to the bottom end of the previous bottom cover and support it on the first bracket and the second bracket to form a stack 5;

[0055] S3: Rotate the rotating member 41 to drive the calibration rod 42 to swing and abut against the stack 5, so that the calibration rod 42 can squeeze the stack 5 from the outer periphery of the stack 5, so that the previous bottom cover and the next bottom cover are stacked vertically, thereby calibrating the center line of the stack 5 into a vertical straight line.

[0056] The specific calibration process of the stacking center calibration method in this embodiment is as follows:

[0057] First, place the bottom cover on the bottom plate 3, and the center of the bottom cover coincides with the center of the bottom plate 3. Then, make the first driving member 2 drive the bottom plate 3 to move vertically upward to move the bottom cover onto the first bracket and the second bracket;

[0058] Then, repeat the above steps to move the next bottom cover to the bottom end of the previous bottom cover and support the whole on the first bracket and the second bracket to form a stack 5;

[0059] Secondly, start the electric cylinder to make the electric cylinder drive the first intermediate member 451 to rotate relative to the axis of the rotating member 41, and the first intermediate member 451 drives one of the two rotating members 41 to rotate; at the same time, the first intermediate member 451 drives the third intermediate member 453 to move, and the third intermediate member 453 drives the second intermediate member 452 to rotate relative to the axis of the other rotating member 41 among the two, and the second intermediate member 452 drives the other rotating member 41 among the two to rotate;

[0060] Finally, the rotating member 41 rotates to drive the connecting member 431 to rotate, and the connecting member 431 rotates to drive the calibration member to swing relative to the axis of the rotating member 41, so that the four calibration rods 42 can respectively squeeze the stack 5 from four directions from the outer periphery of the stack 5, so that each bottom cover can be kept vertically straight, thereby calibrating the center line of the stack 5 into a vertical straight line to avoid the problem of the formed stack 5 tilting and collapsing.

[0061] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
