For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0034] Please refer to Figure 1 and Figure 2 , the automatic roll-changing device 100 and the battery cell preparation system provided in the embodiments of the present utility model can solve the above problems, and will be described in detail below.

[0035] The automatic roll-changing device 100 includes a first reel 110, a second reel 120, a gluing mechanism 130, a cutting mechanism 140, and a tensioning mechanism 150;

[0036] Wherein, the first reel 110 and the second reel 120 are arranged at intervals and form an operation space. The gluing mechanism 130 is located at one end of the operation space, and the cutting mechanism 140 and the tensioning mechanism 150 are located at the other end of the operation space. The tensioning mechanism 150 is arranged farther away from the gluing mechanism 130 than the cutting mechanism 140;

[0037] The first reel 110 and the second reel 120 are used for winding or unwinding the coil material, the gluing mechanism 130 is used for gluing operation, the cutting mechanism 140 is used for tape cutting operation, and the tensioning mechanism 150 is used for tensioning operation.

[0038] During the use of the device, each mechanism can perform operations automatically, which improves the operation efficiency compared with the full-process manual operation. And by defining the layout positions of each mechanism, there is no need to reserve a large manual activity space, which also improves the space utilization rate.

[0039] It should be noted that the automatic roll-changing device 100 may further include a controller. The controller can write a control program in advance. Specifically, the controller can be a single-chip microcomputer of the STM-32 series or a PLC, and is used to communicate with the control elements of each mechanism to send, convert, and receive signals. At the same time, the controller can also store and calculate the status information in the processing flow, which helps to realize the intelligent operation of the overall device.

[0040] Reference Figure 1 and Figure 2 In order to orient the driven coil material, the automatic roll-changing device may further include a deviation rectifying mechanism 160, which is arranged on the side of the tensioning mechanism 150 away from the gluing mechanism 130. When the coil material passes through the deviation rectifying mechanism 160 in a strip form, it will turn to a certain extent, and thus deviation rectification is realized during the turning process to prevent the coil material from deflecting.

[0041] Moreover, there are two sets of tensioning mechanisms 150, which are arranged oppositely. The sides of the two sets of tensioning mechanisms 150 close to each other are used to contact the coil material. That is to say, tensioning wheels for contacting the coil material are arranged on the sides of the two tensioning mechanisms 150 close to each other. The coil material passes between the two tensioning wheels in the form of a tape and contacts one of the tensioning wheels. At the same time, the coil material will also change direction, and thus tension is realized during the direction-changing process to prevent the coil material from being too loose and resulting in poor quality.

[0042] Reference Figure 1 and Figure 2 The automatic roll-changing device 100 further includes a first support base 170. The gluing mechanism 130 is rotatably connected to the first support base 170 so that the gluing mechanism 130 can approach or move away from the first reel 110 or the second reel 120.

[0043] In this embodiment, there is one gluing mechanism 130. One gluing mechanism 130 can perform gluing operations on the coil materials on the first reel 110 and the second reel 120 successively, and the gluing sequence is not limited and can be adjusted according to the actual operation situation.

[0044] Of course, in order to further improve the operation efficiency, the number of the tape sticking mechanisms 130 can be two, and the two tape sticking mechanisms 130 are respectively used for sticking tapes to the first reel 110 and the second reel 120.

[0045] Reference Figure 1 and Figure 2 , the automatic reel changing device 100 further includes a second support base 180. The tensioning mechanism 150 is arranged on the second support base 180, and the cutting mechanism 140 is movably arranged on the second support base 180.

[0046] Specifically, since both the tensioning mechanism 150 and the cutting mechanism 140 are located at the same end of the operation space, in order to reduce the material cost and improve the relative position stability of the two, both of them can be installed on the second support base 180.

[0047] Reference Figure 3 , the cutting mechanism 140 includes a base 141, a driving member 142, a roller body 143 and a cutter 144. The driving member 142 is connected to the roller body 143 and is used to drive the roller body 143 to be movably connected to the base 141, and the cutter 144 protrudes from the roller body 143.

[0048] Specifically, the base 141 is installed on the second support base 180. The base 141 is used for indirectly supporting the roller body 143 to avoid interfering with the relative movement of the roller body 143. The cutter 144 protrudes from the roller body 143 so as to realize the tape cutting operation when the roller body 143 approaches the rolled material.

[0049] And, the driving member 142 includes a rotary power source 1421 and a sliding block 1422. The rotary power source 1421 is coaxially connected to the roller body 143. The roller body 143 is connected to the sliding block 1422. A slide rail 1411 is arranged on the base 141, and the sliding block 1422 is in sliding fit with the sliding block 1422. That is to say, the rotary power source 1421 is used to provide rotary power to make the roller body 143 perform a rotary motion, and the sliding block 1422 is used to drive the roller body 143 to move axially along the slide rail 1411 and make the cutter 144 move synchronously to increase the movement range of the tape cutting operation.

[0050] It should be noted that the rotary power source 1421 can be a rotary motor, a rotary cylinder or a rotary hydraulic cylinder, and the sliding block 1422 can be an electric slider, a pneumatic slider or a hydraulic slider. The specific power forms of the two are not limited.

[0051] Meanwhile, in order to increase the stopping rate of the roller body 143, the cutting mechanism 140 may further include a brake 145 for braking the roller body 143. Specifically, the brake 145 may be located at one end of the roller body 143 close to the rotary power source 1421. When receiving a braking signal, the brake 145 will contact the end face of the roller body 143 to achieve locking, so as to brake the roller body 143.

[0052] Reference Figure 3 , in order to accurately detect the relative position of the roller body 143, the cutting mechanism 140 may further include a sensing element 146. The sensing element 146 includes a first sensor 1461 and a second sensor 1462, and the first sensor 1461 and the second sensor 1462 are respectively used to output circumferential and axial position information of the roller body 143.

[0053] Among them, the first sensor 1461 may be a sensing piece, which is used to be arranged on the lower side of the roller body 143 to obtain the rotation state information of the roller body 143. The second sensor 1462 may be a photoelectric sensor, which is used to be arranged at one end of the slide rail 1411. By obtaining the axial position of the sliding block 1422 on the slide rail 1411, the axial state information of the roller body 143 is output.

[0054] Of course, in other embodiments of the present invention, the first sensor 1461 and the second sensor 1462 may also be other detection elements, and the specific element types of the two are not limited; and the two may also be arranged at other positions, and the specific arrangement positions of the two are not limited.

[0055] An embodiment of the present invention further provides a battery cell preparation system, including the above automatic roll changing device 100, and further including a roll material supply device for outputting a roll material and driving the roll material to move. The battery cell preparation system includes the automatic roll changing device 100, which has all the functions of the automatic roll changing device 100.

[0056] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
