Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to a material roll switching device and a winding equipment. Background Art

[0002] In the complex process of battery cell production, accurate unwinding and efficient rewinding of cathode, anode and separator sheets are key steps to ensure battery performance and production efficiency.

[0003] The core of the existing automatic roll-changing device is that it can quickly cut and separate the tape that is about to be exhausted from the material roll without interrupting the production process, and then accurately connect the front end of the spare material roll with the tail end of the cut tape, thereby achieving seamless roll change. The application of this technology greatly shortens the roll-changing time and reduces the downtime of the production line, providing strong support for the large-scale and continuous production of battery cells.

[0004] During the automatic reel changing process, stable conveying and precise cutting of the strip are the key to ensuring successful reel changing. At present, some automatic reel changing devices lack effective guiding mechanisms when conveying the strip to the cutting structure, such as auxiliary devices such as rubber rollers, which makes it easy for the pole piece roll to collide with other structures during the conveying process due to unstable paths, thereby causing damage or deformation of the edge of the pole piece. In addition, during the subsequent unloading and use process, if the control is not proper, the pole piece may accidentally touch the cutter of the cutting structure, causing scratches, breakage and other quality problems on the surface of the pole piece, which poses a potential threat to the electrical performance, safety performance and overall quality of the battery cell.

DETAILED DESCRIPTION

[0041] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0042] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0046] When automatically switching the material rolls, the front end of the tape of the spare material roll and the rear end of the tape of the working material roll are usually cut synchronously to ensure flatness, and then the front end of the tape of the spare material roll and the rear end of the tape of the working roll are pasted and connected by tape, so that the tape of the working material roll can be automatically switched to the tape of the spare material roll to complete the automatic switching. However, in this process, since there is no way to accurately guide the tape of the spare material roll, when the tape of the spare material roll enters the cutting position, it is easy to touch the adjacent components or cutter, causing damage to the surface of the tape of the spare material roll. When the tape is unwound after pasting, it is also easy to contact and collide with the cutter, causing surface damage. For this reason, the present application mainly realizes guidance by arranging a feed guide roller 300 at the feed port of the cutting and gluing structure 100 and an outlet guide roller 200 at the outlet to prevent the passing tape from touching the cutter or other components and causing damage to its surface.

[0047] It should be noted here that the spare material roll can be understood as the unused material roll, and the working material roll can be understood as the material roll in use. After the working material roll is used up, it needs to be replaced with an unused material roll to ensure that the tape can be unwound normally.

[0048] The present application provides a material roll switching device, which is installed on a fixed plate (not marked in the figure), and the material roll switching device includes a cutting and gluing structure 100, a discharge guide roller 200, a feed guide roller 300 and a driving component 400, wherein the cutting and gluing structure 100 has a feed port and a discharge port, and the cutting and gluing structure 100 includes a cutting component 110 and a gluing component 120, and the cutting component 110 is used to synchronously cut the front end of the tape of the preparation roll and the rear end of the tape of the working roll, so that The gluing assembly 120 is used to fit and connect the front end of the tape of the preparation roll and the rear end of the tape of the working roll; the discharge guide roller 200 is located at the discharge port of the cutting gluing structure 100; the feed guide roller 300 is located at the feed port of the cutting gluing structure 100; the driving assembly 400 has a moving end, which is connected to the feed guide roller 300, and the driving assembly 400 drives the tape guided by the feed guide roller 300 to move to avoid contact with the cutting gluing structure 100.

[0049] In this embodiment, the tape from the preparation roll can be marked as the preparation tape, and the tape from the working roll can be marked as the working tape.

[0050] See also Figure 1 and Figure 2As shown, first, the feed guide roller 300 is moved by the driving assembly 400 so that the feed guide roller 300 and the discharge guide roller 200 form a guide track, and the guide track is used to guide the tape from the first material roll 700 and the second material roll 800 to prevent the outer surface of the tape from being damaged when it touches the cut glue structure 100. In this embodiment, the tape from the first material roll 700 can be used as the working tape, and the tape from the second material roll 800 can be used as the standby tape.

[0051] like Figure 1 As shown, in the initial state, the working tape and the preparation tape both pass through the cutting position and the gluing position of the cutting and gluing structure 100, and the working tape is unwound under the drive of the downstream equipment, and the preparation tape is switched to the winding structure 500 and wound for a certain distance to maintain a tensioned state. In this embodiment, the cutting position and the gluing position of the cutting and gluing structure 100 are located in the same space. When the working tape is about to be used up, the working tape and the preparation tape are cut by the cutting and gluing structure 100. After cutting, the cutting positions of the two are glued together by the gluing component 120. At this time, the second material roll 800 is used to supply material, and the automatic switching of material rolls is completed.

[0052] In this embodiment, the cutting and gluing structure 100, the discharging guide roller 200, the driving assembly 400 and the switching coiling structure 500 are all mounted on a fixed plate (not marked in the figure).

[0053] An unwinding guide roller 600 is disposed at the discharge port of the cutting and gluing structure 100 , and the unwinding guide roller 600 is located in the downstream direction of the discharge guide roller 200 .

[0054] See also Figure 1 It can be seen that the unwinding guide roller 600 guides the switched tape, that is, the unwinding guide is realized.

[0055] The cutting and gluing structure 100 also includes a mounting structure 130, the cutting component 110 is fixedly mounted on the mounting structure 130, the cutting component 110 includes a first linear drive member 111, a movable frame 112 and a mounting member 113, the movable frame 112 is mounted on the driving ends of the two first linear drives 111, the two first linear drives 111 drive the two movable frames 112 to approach or move away from each other, the mounting member 113 is mounted on the movable frame 112, and a cutter 114 is fixedly mounted on the end face of one of the mounting members 113.

[0056] See also Figure 3 , Figure 5 and Figure 6As shown, in this embodiment, there are two first linear drive members 111, which are respectively located on both sides of the tape, and there are also two corresponding movable frames 112 and mounting members 113, which are distributed on the left and right, and a cutter 114 is installed on one of the mounting members 113. Specifically, the two mounting members 113 are driven to approach each other by the two first linear drive members 111, and the preparation tape and the working tape between the two are cut off by the cutter 114 during the movement, so as to prepare for the subsequent gluing connection.

[0057] In this embodiment, since the subsequent gluing process requires the mounting member 113 to rotate, the mounting member 113 is rotatably mounted on the moving frame 112 .

[0058] The glue sticking assembly 120 includes a second linear drive member 121 hingedly mounted on the movable frame 112, the driving end of the second linear drive member 121 is hingedly connected to the mounting member 113, a suction cup 123 is fixedly mounted on the end face of the mounting member 113, and an adsorption plate 122 is arranged on the other end face of the mounting member 113, wherein the adsorption plate 122 is arranged at a ninety-degree angle with the suction cup 123.

[0059] See also Figures 3 to 6 As shown, in the initial state, a connecting tape is adsorbed and arranged on each adsorption plate 122. In the present embodiment, the second linear drive member 121, the adsorption plate 122 and the suction cup 123 are divided into left and right parts, i.e., the left second linear drive member 121, the left adsorption plate 122, the left suction cup 123, the right second linear drive member 121, the right adsorption plate 122 and the right suction cup 123, and the cutter 114 is installed on the right mounting member 113.

[0060] Specifically, while the cutter 114 cuts the spare tape and the operating tape, the left suction cup 123 adsorbs the two. At this time, the spare tape and the operating tape at the cutting position are both adsorbed by the left suction cup 123. Next, the right second linear drive member 121 is started to drive the right mounting member 113 to rotate so that the right adsorption plate 122 faces the operating tape and the spare tape. Then the right first linear drive member 111 is started again to make the tape on the right adsorption plate 122 fit and connect the spare tape and the operating tape (the connection between the spare tape and the operating tape). After that, the left suction cup 123 releases the adsorption of the spare tape and the operating tape. At this time, since the spare tape and the operating tape are connected by the tape on the right adsorption plate 122, the adsorption plate 122 is in a state of continuing to adsorb the tape. Next , the second linear drive member 121 on the right side drives the mounting member 113 to rotate so that the adsorption plate 122 faces the preparation tape and the working tape, and then the first linear drive member 111 on the left side drives the left adsorption plate 122 to move toward the preparation tape and the working tape, and after moving a certain distance, the tape on the left adsorption plate 122 is adhered to the preparation tape and the working tape (the connection between the two), at this time, the left and right sides of the connection between the working tape and the preparation tape are adhered with connecting tape, and then the adsorption plates 122 on the left and right sides are released from the adsorption state, and the two mounting members 113 are driven to return to the initial position by the first linear drive members 111 on both sides, and the mounting members 113 on both sides are rotated by the second linear drive members 121 on both sides to restore the adsorption plates 122 on both sides to the initial position, waiting for the next gluing process.

[0061] In this embodiment, the first linear drive member 111 and the second linear drive member 121 are both cylinders. Of course, they can also be other components as needed, such as linear motors, cylinders and other linear drive structures, which are not specifically limited here.

[0063] See also Figure 1 and Figure 7 As shown, the position of the mounting plate 134 can be changed by moving the first slider 133 on the first guide rail 132, thereby changing the position of the first linear drive member 111, and adjusting the position according to different tape width requirements.

[0064] In this embodiment, the first guide rail 132 is two guide rods, and can certainly be of other shapes or structures as long as it can play a guiding role.

[0065] The driving assembly 400 includes a second guide rail 410, on which a second slider 420 is slidably mounted. The second slider 420 is the moving end of the driving assembly 400, and the feed guide roller 300 is mounted on the second slider 420. A third linear driving member 430 is fixedly mounted on the second guide rail 410 for driving the second slider 420 to slide.

[0066] See also Figure 8 As shown, the second slider 420 is driven by the third linear drive member 430 to move under the guidance of the second guide rail 410, thereby changing the position of the feed guide roller 300 to prevent the web guided by the feed guide roller 300 from contacting the cutter 114 or other components and causing damage.

A transmission belt 530 is provided between the power output end of the rotating drive member 520 and the power input end of the reel 510. The transmission belt 530 is used to transmit the power of the rotating drive member 520 to the reel 510.

[0069] See also Figure 1 , Fig. 9 as well as Fig.10 As shown, in order to enable the preparation tape to be located at the cutting position of the cutting adhesive bonding structure 100, the preparation tape needs to be made vertical and tensioned. Specifically, in the initial state, a portion of the preparation tape is wound on the reel 510. Specifically, the reel 510 is driven to rotate by the rotating drive member 520 through the transmission belt 530, thereby making the preparation tape vertically located at the cutting space position of the cutting adhesive bonding structure 100.

[0070] Furthermore, in this embodiment, there are two reels 510, which are respectively located on both sides of the discharge port of the cut adhesive structure 100. The two reels 510 are rotatably mounted on the fixed plate. For details, please refer to Figure 1 and Figure 2 shown.

A tensioning wheel 544 is provided in the installation cavity 542, and the end of the tensioning wheel 544 is slidably set in the sliding groove 543, and the outer surface of the tensioning wheel 544 is in close contact with the transmission belt 530.

[0073] See also Fig. 9 and Fig.10 As shown, in order to enable the power of the rotating drive member 520 to be transmitted to the reel 510 through the transmission belt 530, it is necessary to tension the transmission belt 530 through the tensioning wheel 544. The present application mainly realizes the tensioning through the gravity of the tensioning wheel 544. Specifically, the tensioning wheel 544 slides up and down in the sliding groove 543. Under the action of gravity, the tensioning wheel 544 slides downward in the sliding groove 543 and acts on the transmission belt 530, thereby realizing the tensioning of the transmission belt 530.
