[0038] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0039] Embodiment 1

[0040] This embodiment relates to a material changing mechanism for a slitting and laminating device, which can improve the material changing efficiency and the stability after material changing, and can effectively improve problems such as difficult material changing operation and poor tape splicing caused by manual material changing.

[0041] In terms of the overall structure, as Figures 1 to 3 shown, the material changing mechanism for the slitting and laminating device of this embodiment includes a first material feeding unit 1 and a second material feeding unit 2 arranged oppositely, and a first tape splicing assembly 3 and a second tape splicing assembly 4 arranged oppositely. Among them, the first material feeding unit 1 and the second material feeding unit 2 are respectively used for unreeling a first tape and a second tape. Both the first tape splicing assembly 3 and the second tape splicing assembly 4 are located on the conveying path of the tape, and both have a tape fixing unit and an adhesive preparation unit 302, and a cutting knife 100 is provided on either the first tape splicing assembly 3 or the second tape splicing assembly 4.

[0042] The cutting knife 100 can cut the first tape and the second tape simultaneously. The tape fixing unit can fix the part of the first tape in the production state after cutting, and the part of the second tape in the standby state after cutting. The adhesive preparation unit 302 can bond the tape 20 at the butt joint position of the first tape part 10a and the second tape part 10b.

[0043] At this time, in the above structure, by setting the first material feeding unit 1 and the second material feeding unit 2 arranged oppositely, and the first tape splicing assembly 3 and the second tape splicing assembly 4 arranged oppositely, and enabling the cutting knife 100 to cut the first tape and the second tape simultaneously, the part 10a of the first tape in the production state and the part 10b of the second tape in the standby state after cutting can be fixed on the tape fixing unit, and the tape 20 in the adhesive preparation unit 302 is used to bond the first tape part 10a and the second tape part 10b together, thereby realizing the rapid splicing of the tape, improving the material changing efficiency and the stability after material changing, and thus effectively improving problems such as difficult material changing operation, poor tape splicing, and tape breakage caused by manual material changing.

[0044] It should be noted that the first tape and the second tape of this embodiment can be, for example, both a positive electrode tape, a negative electrode tape, or an insulating film tape, etc.

[0045] Based on the above overall structure, in detail, continue to refer to Figures 1 to 3 shown. In this embodiment, the first material feeding unit 1 and the second material feeding unit 2 are arranged oppositely, and the first tape splicing assembly 3 and the second tape splicing assembly 4 are arranged oppositely. Among them, taking the tape unreeled by the first material feeding unit 1 as the production tape and the tape unreeled by the second material feeding unit 2 as the standby tape as an example for detailed description, when the tape on the first material feeding unit 1 is about to run out, it is beneficial for the first tape splicing assembly 3 and the second tape splicing assembly 4 to connect the standby tape on the second material feeding unit 2 to the production tape, that is, to realize the material change of the tape.

[0046] Of course, it can be understood that the tape unreeled by the second feeding unit 2 can also be used as the production tape. At this time, the tape unreeled by the first feeding unit 1 can be used as the spare tape. In this way, the tape can be replaced alternately, which is conducive to realizing tape replacement without stopping the machine.

[0047] As a preferred embodiment, in this embodiment, over-roller assemblies are provided upstream and downstream of each tape fixing unit, and the conveyed tape winds around the over-roller assemblies. The setting of the over-roller assemblies can ensure the reliability of the conveyance of the first tape or the second tape and improve the conveyance effect of the tape. Moreover, also as a preferred embodiment, in this embodiment, the first tape connecting assembly 3 and the second tape connecting assembly 4 both further include stock rollers, and the tape in the stock state winds around the tape fixing unit on the corresponding side and is pre-wound on the stock rollers. By providing the stock rollers, it is beneficial to the stock preparation of the tape, so that the tape can quickly enter the tape connecting state.

[0048] Specifically, the over-roller assembly includes a first over-roller 11, a second over-roller 22, a third over-roller 33, a fourth over-roller 44, a fifth over-roller 55, a sixth over-roller 66, a seventh over-roller 77, and an eighth over-roller 88. Among them, the first over-roller 11, the second over-roller 22, the third over-roller 33, and the fourth over-roller 44 are located upstream of the tape fixing unit, and the fifth over-roller 55, the sixth over-roller 66, the seventh over-roller 77, and the eighth over-roller 88 are located downstream of the fixing unit. And preferably, the third over-roller 33 and the fourth over-roller 44, as well as the fifth over-roller 55 and the sixth over-roller 66, are respectively arranged close to the tape fixing unit. For the convenience of distinction, the stock roller on the first tape connecting assembly 3 is defined as the first stock roller 303, and the stock roller on the second tape connecting assembly 4 is defined as the second stock roller 403. The tape fixing unit in the first tape connecting assembly 3 is defined as the first tape fixing unit 301, and the tape fixing unit in the second tape connecting assembly 4 is defined as the second tape fixing unit 401.

[0049] During specific implementation, the first tape unreeled by the first unreeling unit, that is, the production tape, successively winds around the first over-roller 11, the third over-roller 33, the fifth over-roller 55, and the seventh over-roller 77, and is conveyed to the downstream process. The second tape unreeled by the second unreeling unit, that is, the spare tape, successively winds around the second over-roller 22, the fourth over-roller 44, and the sixth over-roller 66, and is wound around the stock roller on the corresponding side, that is, wound around the second stock roller 403.

[0050] Still referring to Figures 1 to 3 As shown, in this embodiment, the two opposite tape fixing units can approach each other in the first direction and clamp the first tape and the second tape. At this time, the two tape fixing units can approach each other in the first direction and clamp the first tape and the second tape, which is beneficial to improving the cutting quality of the first tape and the second tape and ensuring the subsequent tape bonding quality.

[0051] As a preferred embodiment, in this embodiment, each tape fixing unit includes two adsorption plates for respectively adsorbing the first tape or the second tape. The cutting knife 100 is slidably disposed on one of the adsorption plates and is located between the two adsorption plates, and the cutting knife 100 can move relative to the adsorption plate in the first direction to simultaneously cut the first tape and the second tape. At this time, the arrangement of the two adsorption plates can not only fix the first tape and the second tape well, but also facilitate the arrangement of the cutting knife 100.

[0052] Moreover, as a further preferred embodiment, the two adsorption plates in each tape fixing unit can move away from each other in the second direction to form an avoidance space therebetween. The docking positions on the first tape and the second tape correspond to the avoidance space, and the tape 20 in the glue supply unit 302 can move into the avoidance space. Among them, the first direction and the second direction are orthogonally arranged as Figure 2 shown.

[0053] In this way, by enabling the two adsorption plates in each tape fixing unit to move away from each other in the second direction to form an avoidance space therebetween, on the one hand, it is convenient to expose the docking positions of the first tape portion 10a and the second tape portion 10b, and on the other hand, it is beneficial for the tape 20 in the glue supply unit 302 to move into the avoidance space and be bonded to the docking position, so that the first tape and the second tape are bonded together.

[0054] Still referring to Figures 1 to 4 shown, in this embodiment, the first tape connecting assembly 3 and the second tape connecting assembly 4 are both arranged on the frame, and the first tape connecting assembly 3 and the second tape connecting assembly 4 are basically the same in structure, except that the second tape connecting assembly 4 is provided with a movable cutting knife 100. It can be understood that the cutting knife 100 can also be arranged on the first tape connecting assembly 3. For better understanding of this solution, the following will take the second tape connecting assembly 4 as an example for detailed description.

[0055] Specifically in terms of structure, from Figure 4 and in combination with Figures 1 to 3 shown, in this embodiment, the frame 1 is provided with a first driving part 101 and a first mounting plate 102, as well as a second driving part 103 and a second mounting plate 104. The first mounting plate 102 is connected to the first driving part 101 and can move in the first direction under the drive of the first driving part 101, and the second mounting plate 104 is connected to the second driving part 103 and can also move in the first direction under the drive of the second driving part 103.

[0056] In addition, two third driving parts 105 are provided on the first mounting plate 102, and two third mounting plates 106 respectively connected to the two third driving parts 105. Two fourth driving parts 107 are provided on the second mounting plate 104, and two fourth mounting plates 108 respectively connected to the two fourth driving parts 107. Driven by the corresponding connected third driving parts 105, the two third mounting plates 106 can both move along the second direction. Driven by the corresponding connected fourth driving parts 107, the two fourth mounting plates 108 can also both move along the second direction.

[0057] In the above-mentioned first tape fixing unit 301, the two suction plates, namely the first suction plate 111 and the second suction plate 222, are respectively connected to the two third mounting plates 106. The two suction plates in the second tape fixing unit 401, namely the third suction plate 333 and the fourth suction plate 444, are respectively connected to the two fourth mounting plates 108. In this way, the two suction plates in the opposite tape fixing units can both move closer to each other along the first direction to clamp the first tape and the second tape. And the two suction plates in each tape fixing unit can also move closer to or away from each other along the second direction respectively. After moving away from each other, an avoidance space is formed between the two suction plates to avoid the tape fixing plate 51, which is convenient for the tape 20 to be bonded at the docking position of the first tape part 10a and the second tape part 10b, that is, to bond the production tape and the spare tape together.

[0058] It should be noted here that after the cutter 100 cuts the first tape and the second tape at the same time, the first tape is cut into a first waste part 20a and a first tape part 10a in the production state, that is, Figure 1 as shown in the first waste part 20a and the production tape. The second tape is cut into a second waste part 20b close to the second spare roller 403 and a spare tape part (the second tape part 10b).

[0059] In this embodiment, the glue preparation unit 302, as a preferred embodiment, the glue preparation unit 302 includes a tape fixing plate 51, a glue preparation driving part 54, and a first moving frame 53 connected to the glue preparation driving part 54. The tape fixing plate 51 is provided with a tape fixing part for fixing the tape 20 of a preset length. The tape fixing plate 51 is rotatably arranged on the moving frame 53, and the tape fixing plate 51 can rotate between a first position and a second position. In the first position, the tape 20 is operatively fixed on the tape fixing plate 51. In the second position, the glue preparation driving part 54 drives the moving frame 53 to move, and the moving frame 53 drives the tape fixing plate 51 to move to the docking position and bond the first tape part 10a and the second tape part 10b together.

[0060] In this way, the glue preparation driving part 54 is connected to the moving frame 53, and the tape fixing plate 51 is rotatably arranged on the moving frame 53. In this way, when the tape fixing plate 51 is in the first position, the tape 20 can be fixed on the tape fixing plate 51, and after rotating to the second position, under the drive of the glue preparation driving part 54, the moving frame 53 moves, driving the tape fixing plate 51 to move, so that the tape 20 is bonded at the docking position, and further bonding the first tape part 10a and the second tape part 10b together.

[0061] In this embodiment, the tape fixing part includes a plurality of vacuum adsorption holes provided on the tape fixing plate 51, and the protective film in the tape is adsorbed on the tape fixing plate 51 through the plurality of vacuum adsorption holes. The plurality of vacuum adsorption holes provided on the tape fixing plate 51 enable the protective film in the tape to be adsorbed on the tape fixing plate 51 through the plurality of vacuum adsorption holes, thereby facilitating the fixing of the tape 20 and ensuring the fixing effect of the tape 20.

[0062] As a preferred implementation manner, in this embodiment, each glue preparation unit 302 is also provided with an installation part 52 for installing the tape roll 6, and the tape 20 on the tape roll 6 can be pulled out along a preset path and fixed on the tape fixing plate 51. The setting of the installation part 52 is beneficial to the installation of the tape roll 6, thereby facilitating the rapid fixing of the tape 20 with a preset size on the tape fixing plate 51. In addition, preferably, in this embodiment, a scale 511 is also provided on the tape fixing plate 51, which is beneficial to ensuring the preset size of the tape 20.

[0063] In addition, the material changing mechanism of the cutting and stacking equipment in this embodiment also includes a partition plate 5, which can move and at least separate the first tape connecting assembly 3 and the second tape connecting assembly 4. As shown in the figure, the partition plate 5 includes a plurality of sub-plate bodies connected in sequence, and adjacent sub-plate bodies can move relative to each other in the first direction, that is, the plurality of sub-plate bodies can move to an extended state to separate the first tape connecting assembly 3 and the second tape connecting assembly 4, and the plurality of sub-plate bodies can also move to a retracted state to cancel the separation of the first tape connecting assembly 3 and the second tape connecting assembly 4.

[0064] When the material changing device of the cutting and stacking equipment in this embodiment is specifically used, in the normal state, the partition plate 5 is in the retracted state to facilitate the automatic connection of the tape on the second unwinding unit to the production tape, and the whole vehicle is fed through the seventh idler roller 77 or the eighth idler roller 88 for production. When feeding is required, the partition plate 5 is in the extended state to separate the first unwinding unit and the second unwinding unit, as well as the first tape connecting assembly 3 and the second tape connecting assembly 4. Then, the operator manually places the prepared material roll on the unwinding shaft, threads the tape through the corresponding material preparation roller on the corresponding side, and then the tape connecting operation can be carried out.

[0065] Look back Figure 1As shown, the production tape on the first unwinding unit sequentially passes around the first guide roller 11, the third guide roller 33, the fifth guide roller 55, and the seventh guide roller 77, and is conveyed to the downstream process. The spare tape on the second unwinding unit sequentially passes around the second guide roller 22, the fourth guide roller 44, the sixth guide roller 66, and is wound around the second spare material roller 403. When starting to splice the tapes, first, manually fix the tape 20 on the tape fixing plate 51, then rotate the tape fixing plate 51 by 90° and push it into the designated position on the moving frame 53.

[0066] When starting to splice the tapes, the first tape fixing unit 301 and the second tape fixing unit 401 approach each other along the first direction, clamp the first tape and the second tape, and adsorb and fix the first tape through the first adsorption plate 111 and the second adsorption plate 222, and adsorb and fix the second tape through the third adsorption plate 333 and the fourth adsorption plate 444. Then, the cutting knife 100 extends and simultaneously cuts the first tape and the second tape. After the tapes are cut, release the first tape and the second tape, and release the adsorption of the second adsorption plate 222 and the third adsorption plate 333. At this time, the first remaining material part 20a is recycled to the first feeding roller, and the second remaining material part 20b is recycled to the second spare material roller 403.

[0067] After the tapes are recycled, make the first tape fixing unit 301 and the second tape fixing unit 401 approach each other again and be in the clamped state. Then, remove the adsorption of the fourth adsorption plate 444, and at the same time, the second adsorption plate 222 adsorbs the spare tape part. At this time, the spare tape part is transferred from the fourth adsorption plate 444 to the second adsorption plate 222 and is adsorbed and fixed by the second adsorption plate 222. Then, the third adsorption plate 333 and the fourth adsorption plate 444 move away from each other along the second direction to form an avoidance space. Then, the tape 20 on the tape fixing plate 51 approaches the butt joint position of the first tape part 10a and the second tape part 10b under the drive of the tape preparation driving part 54, and bonds the tape 20 at the butt joint position, so that the first tape part 10a and the second tape part 10b, that is, the production tape and the spare tape, are connected together. Thus, the tape splicing is completed, and the equipment can feed and produce normally.
