Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a glue preparation mechanism and a glue sticking device. Background Art

[0002] In the production process of lithium batteries, multiple material strips (such as cathode sheets, separators and anode sheets) need to be wound to form battery cells. Before the material strips enter the winding device for winding, a tape segment needs to be pasted on the material strips by a glue sticking mechanism. Generally, in order to ensure the efficiency of battery cell preparation, the glue preparation mechanism needs to continuously prepare glue to continuously provide the glue sticking mechanism with a preset length of tape segment.

[0003] In the conventional technology, the glue preparation mechanism realizes continuous glue preparation by means of automatic tape splicing, in the following manner: the working tape and the backup tape are connected to each other by utilizing their own adhesiveness, and after the two are bonded, the working tape automatically transports the backup tape downstream.

[0004] However, in the above method, since the working tape and the spare tape have weak adhesion, it is easy to cause failure in splicing, thereby affecting the continuous glue preparation effect, resulting in low glue preparation efficiency, and further affecting the production capacity of the equipment. Utility Model Content

[0005] Based on this, it is necessary to provide a glue preparation mechanism and glue sticking device that can ensure continuous glue preparation effect, improve continuous glue preparation efficiency, and thus increase production capacity, in order to address the problem that the continuous glue preparation effect of the glue preparation mechanism in traditional technology is poor, resulting in low glue preparation efficiency.

[0012] The first driving assembly includes a plurality of first driving members, each of the sandwiching assemblies is connected to one of the first driving members, and each of the first driving members is used to drive the corresponding sandwiching assemblies to move.

[0013] In one embodiment, the laminating assembly includes a laminating driving member, a first laminating block and a second laminating block, at least one of the first laminating block and the second laminating block is connected to the laminating driving member, and the laminating driving member is used to drive the laminating block connected thereto to move so that the first laminating block and the second laminating block are moved closer or farther away to clamp or loosen the tape.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0032] See also Figure 1 and Figure 2 An embodiment of the present application provides a glue sticking device, including a glue preparation mechanism 100 and a glue sticking mechanism, wherein the glue preparation mechanism 100 is used to provide a tape segment to the glue sticking mechanism, and the glue sticking mechanism is used to stick the tape segment to a material strip. Specifically, the material strip is a pole piece material strip.

[0033] The adhesive preparation mechanism 100 includes an unwinding assembly 10 and an adhesive sandwich assembly 20. The unwinding assembly 10 is used to unwind and output the adhesive tape 400, and the adhesive sandwich assembly 20 is arranged downstream of the unwinding assembly 10 and is used to clamp the adhesive tape 400 unwinded and output by the unwinding assembly 10. Optionally, the unwinding assembly 10 includes an unwinding shaft, and the adhesive disc 300 is installed on the unwinding shaft, and the unwinding shaft drives the adhesive disc 300 to rotate to unwind and output the adhesive tape 400. The adhesive tape 400 unwinded and output by the unwinding assembly 10 can be manually threaded through the adhesive sandwich assembly 20.

[0034] Furthermore, the number of the unwinding components 10 and the number of the laminating components 20 are at least two, and each laminating component 20 is arranged corresponding to one unwinding component 10, and the laminating component 20 can clamp the tape 400 unwound and output by the corresponding unwinding component 10. Figure 1 and Figure 2 In some specific implementations, the number of the unwinding components 10 and the number of the laminating components 20 are both two. Of course, in some other implementations, the number of the unwinding components 10 and the laminating components 20 can also be three or more than three, which is not limited here.

[0035] The adhesive preparation mechanism 100 further includes a buffer assembly 30 , which is located between the unwinding assembly 10 and the adhesive clamping assembly 20 for buffering the adhesive tape 400 .

[0036] The glue preparation mechanism 100 also includes a first glue cutting component 40 and a glue pulling component 50 located downstream of the glue sandwich component 20, and the first glue cutting component 40 is arranged between the glue sandwich component 20 and the glue pulling component 50. It should be noted here that the first glue cutting component 40 and the glue pulling component 50 are located downstream of the glue sandwich component 20, and the first glue cutting component 40 is arranged between the glue sandwich component 20 and the glue pulling component 50, which means that in the conveying direction of the adhesive tape 400, the first glue cutting component 40 and the glue pulling component 50 are located downstream of all the glue sandwich components 20, and the first glue cutting component 40 and the glue pulling component 50 are arranged in sequence, so that the glue pulling component 50 can pull out the adhesive tape 400 clamped by the glue sandwich component 20, and the first glue cutting component 40 can cut the adhesive tape 400 pulled out by the glue pulling component 50 to form an adhesive tape segment. That is, the part of the adhesive tape 400 pulled out by the glue pulling component 50 can be cut off and separated from other parts by the first glue cutting component 40 to form an adhesive tape segment.

[0037] Further, the glue-clamping assembly 20 can move relative to the first glue-cutting assembly 40 and the glue-pulling assembly 50, so that the glue-clamping assembly 20 is selectively opposite to the glue-pulling assembly 50. The glue-pulling assembly 50 is used to pull out the tape 400 clamped by the glue-clamping assembly 20 opposite to it, and the first glue-cutting assembly 40 is used to cut the tape 400 pulled out by the glue-pulling assembly 50 to form a tape segment. That is, all the glue-clamping assemblies 20 can move relative to the first glue-cutting assembly 40 and the glue-pulling assembly 50, and can switch between a first position relative to the glue-pulling assembly 50 and a second position misaligned with the glue-pulling assembly 50. When the glue-clamping assembly 20 is in the first position, the glue-pulling assembly 50 can pull out the tape 400 clamped by the glue-clamping assembly 20. At the same time, when one of the glue-clamping assemblies 20 is in the first position, the other glue-clamping assemblies 20 are all in the second position.

[0038] It should be noted that when the adhesive pulling component 50 pulls the adhesive tape 400 from the adhesive clamping component 20, the adhesive clamping component 20 loosens the adhesive tape 400. When the first adhesive cutting component 40 cuts the adhesive tape 400, the adhesive clamping component 20 clamps the adhesive tape 400 again, and at this time, the adhesive pulling component 50 tightens the adhesive tape 400, and the first adhesive cutting component 40 cuts the adhesive tape 400. Optionally, when the first adhesive cutting component 40 cuts the adhesive tape 400, the suction cup 200 of the adhesive sticking mechanism is used to support the adhesive tape 400, and the first adhesive cutting component 40 cooperates with the suction cup 200 to cut the adhesive tape 400.

[0039] When the glue preparation mechanism 100 is working, it controls one glue clamping component 20 to move to the first position, and the other glue clamping components 20 are in the second position. The glue pulling component 50 pulls out the tape 400 (the tape is the working tape) clamped by the glue clamping component 20 in the first position, and the glue clamping component 20 clamps the tape 400. The first glue cutting component 40 cuts the tape 400 at the position between the glue clamping component 20 and the glue pulling component 50, and cuts the tape 400 to form a tape segment with a preset length. The suction cup 200 absorbs the tape segment provided by the glue preparation mechanism 100 and sticks the tape segment to the material tape. While cutting the tape 400 clamped by the glue clamping component 20 in the first position, a spare glue disc is installed on the unwinding component 10 corresponding to the glue clamping component 20 in the second position, and the spare glue disc is unwound to form a spare tape. When the working rubber disc on the unwinding assembly 10 corresponding to the laminating assembly 20 at the first position has finished unwinding, the laminating assembly 20 at the first position is controlled to move to the second position, and the other laminating assembly 20 at the second position moves to the first position to continue working, and the cycle repeats.

[0040] The glue preparation mechanism 100 in the present application, the glue clamping component 20 can switch positions, realize the automatic tape change between the working tape and the spare tape, and the glue pulling component 50 can work continuously to pull glue, ensuring the continuous glue preparation of the glue preparation mechanism 100. Different from the prior art that realizes continuous glue preparation by automatic tape splicing, the present application does not need to bond the working tape and the spare tape, ensuring the smooth automatic tape change, making the continuous glue preparation effect of the glue preparation mechanism 100 better, so that the glue preparation efficiency is improved, so that the equipment meets the production capacity requirements.

[0041] In some embodiments, the glue preparation mechanism 100 further includes a mounting plate 60, and the unwinding assembly 10, the glue clamping assembly 20, the first glue cutting assembly 40, and the glue pulling assembly 50 are all mounted on the mounting plate 60. Such a configuration makes the glue preparation mechanism 100 more integrated, and thus enables the glue preparation mechanism 100 to occupy a smaller area. It is conceivable that in some other embodiments, the glue preparation mechanism 100 can also omit the mounting plate 60, and in this case, the components of the glue preparation mechanism 100 are dispersedly arranged.

[0042] See also Figure 3The laminating assembly 20 includes a laminating driving member 21, a first laminating block 22 and a second laminating block 23, and at least one of the first laminating block 22 and the second laminating block 23 is connected to the laminating driving member 21. The laminating driving member 21 is used to drive the laminating blocks connected thereto to move, so that the first laminating block 22 and the second laminating block 23 are close to or away from each other to clamp or loosen the adhesive tape 400. Optionally, the laminating driving member 21 can select a cylinder or a motor, etc. In this way, when the laminating assembly 20 is in the second position, the adhesive tape 400 unwound and output by the unwinding assembly 10 can be inserted between the first laminating block 22 and the second laminating block 23, and the laminating driving member 21 makes the two laminating blocks close to each other to clamp the adhesive tape 400, so as to facilitate the clamping of the adhesive tape 400. After the two laminating blocks clamp the adhesive tape 400, the laminating assembly 20 is controlled to move from the second position to the first position. Of course, in some other embodiments, the clamping assembly 20 can also be configured in other ways as long as the purpose of clamping the tape 400 can be achieved.

[0043] In some embodiments, see Figure 1 and Figure 2 The glue preparation mechanism 100 further includes a first drive assembly 70, and the glue clamping assembly 20 is connected to the first drive assembly 70. The first drive assembly 70 is used to drive the glue clamping assembly 20 to move relative to the mounting plate 60, so that the glue clamping assembly 20 is selectively opposite to the glue pulling assembly 50. By setting the first drive assembly 70, the glue clamping assembly 20 automatically moves relative to the mounting plate 60, and the degree of automation is high.

[0044] In some specific implementations, please refer to Figure 1 The first driving assembly 70 includes a first driving member 71 and a moving plate 72. The moving plate 72 is slidably disposed on the mounting plate 60 and connected to the first driving member 71. All the laminated components 20 are sequentially arranged on the moving plate 72 at intervals. The first driving member 71 is used to drive the moving plate 72 to move, and the moving plate 72 drives the laminated components 20 to move. Multiple laminated components 20 are driven by the same first driving member 71, which simplifies the structure of the adhesive preparation mechanism 100. The first driving member 71 can be selected from a cylinder or a motor.

[0045] Optionally, the glue preparation mechanism 100 further includes a first guide assembly, and the first guide assembly includes a first slider and a first guide rail 80 that cooperate with each other. One of the first slider and the first guide rail 80 is arranged on the mounting plate 60, and the other is arranged on the movable plate 72. The first slider cooperates with the first guide rail 80 to guide the movable plate 72, and then guides the glue clamping assembly 20. The first guide rail 80 extends along a first direction, and the extension direction of the first guide rail 80 is also the movement direction of the first driving member 71 driving the movable plate 72, and is also the movement direction of the glue clamping assembly 20 relative to the mounting plate 60. When the glue clamping assembly 20 moves along the first direction, the glue clamping assembly 20 can switch between the first position and the second position, and the first slider cooperates with the first guide rail 80 to guide the glue clamping assembly 20 to prevent the glue clamping assembly 20 from running off in the first direction. When the glue clamping assembly 20 is in the first position, the glue clamping assembly 20 can be opposite to the glue pulling assembly 50 in the second direction (described below). After the glue pulling assembly 50 pulls out the adhesive tape 400, the part where the adhesive tape 400 is pulled out extends along the second direction.

[0046] In some other specific embodiments, the first drive assembly 70 includes a plurality of first drive members 71, and the plurality of first drive members 71 are disposed on the mounting plate 60. Each of the laminated components 20 is connected to a first drive member 71, and each first drive member 71 is used to drive the movement of the corresponding laminated component 20. Each laminated component 20 is driven by a different first drive member 71, so that the movement of the laminated component 20 can be independently controlled.

[0047] Continue reading Figure 1 The first rubber cutting assembly 40 includes a first rubber cutting driver 41 and a first cutter 42. The first rubber cutting driver 41 is mounted on the mounting plate 60, and the first cutter 42 is connected to the first rubber cutting driver 41. The first rubber cutting driver 41 is used to drive the first cutter 42 to move to cut the tape 400. Optionally, the first rubber cutting driver 41 is used to drive the first cutter 42 to move along a first direction, and at this time, the first cutter 42 is perpendicular to the tape 400, so as to facilitate cutting the tape 400 to form a tape segment. Among them, the first rubber cutting driver 41 can select a cylinder or a motor, etc.

[0048] The adhesive pulling assembly 50 includes an adhesive pulling driving member 51 and a clamping jaw 52. The adhesive pulling driving member 51 is mounted on the mounting plate 60, and the clamping jaw 52 is connected to the adhesive pulling driving member 51. The clamping jaw 52 is used to clamp the adhesive tape 400, and the adhesive pulling driving member 51 is used to drive the clamping jaw 52 to move to pull out the adhesive tape 400. Optionally, the adhesive pulling driving member 51 adopts a servo drive to meet the adhesive pulling requirements of adhesive tapes 400 of various lengths. The adhesive pulling driving member 51 can select a cylinder or a motor, etc.

[0049] It is understandable that in some other embodiments, the first glue cutting component 40 and the glue pulling component 50 may also be arranged in other ways, as long as the effects of glue cutting and glue pulling can be achieved, and no limitation is made here.

[0050] In some embodiments, continue to refer to Figure 1 and Figure 2 , the glue preparation mechanism 100 also includes a second drive assembly 90, each of the glue clamping assemblies 20 is connected to a second drive assembly 90, and the second drive assembly 90 is used to drive the corresponding glue clamping assemblies 20 to move close to or away from the first glue cutting assembly 40. Specifically, the second drive assembly 90 is used to drive the corresponding glue clamping assemblies 20 to move close to or away from the first glue cutting assembly 40 along the second direction. In this way, when the glue clamping assemblies 20 are in the first position, the glue clamping assemblies 20 in the first position are close to the first glue cutting assembly 40 in the second direction, and the glue pulling assembly 50 can grab the adhesive tape 400 clamped by the glue clamping assemblies 20. When the glue clamping assemblies 20 are in the second position, the glue clamping assemblies 20 are controlled to move away from the first glue cutting assembly 40 in the second direction, and the first glue cutting assembly 40 will not interfere with the tape threading of the glue clamping assemblies 20, thereby reducing the occurrence of the first glue cutting assembly 40 being too close to the glue clamping assemblies 20 being threaded and causing harm to personal safety.

[0051] It should be noted that the second direction and the first direction both intersect with the width direction of the tape 400. Specifically, the width direction, the second direction and the first direction of the tape 400 are perpendicular to each other. Figure 1 and Figure 2 The middle Z direction, the second direction is Figure 1 and Figure 2 In the X direction, the width direction is Figure 1 Center Y direction.

[0052] Specifically, the second driving assembly 90 includes a second driving member 91 and a mounting seat 92 both mounted on the moving plate 72 . The mounting seat 92 is connected to the second driving member 91 , and the laminated assembly 20 is disposed on the mounting seat 92 .

[0053] Furthermore, the laminating assembly 20 further includes a support seat 24, which is mounted on the mounting seat 92, and the laminating driving member 21 is mounted on the support seat 24. The mounting seat 92 is provided with a roller 110, which is provided upstream of the laminating assembly 20 to guide the adhesive tape 400 to the laminating assembly 20.

[0054] Furthermore, the glue preparation mechanism 100 further includes a second guide assembly, which includes a second slider and a second guide rail 120 that cooperate with each other. One of the second slider and the second guide rail 120 is disposed on the movable plate 72, and the other is disposed on the mounting seat 92. The second slider cooperates with the second guide rail 120 to guide the mounting seat 92, and further guides the glue sandwich assembly 20. The second guide rail 120 extends along the second direction, and the extension direction of the second guide rail 120 is also the movement direction of the second driving assembly 90 driving the glue sandwich assembly 20. When the glue sandwich assembly 20 moves along the second direction, the second slider cooperates with the second guide rail 120 to guide the glue sandwich assembly 20, so as to prevent the glue sandwich assembly 20 from running off in the second direction.

[0055] In some embodiments, see Figure 2 and Figure 3 The adhesive preparation mechanism 100 further includes a second adhesive cutting assembly 130. Each adhesive sandwich assembly 20 is provided with a second adhesive cutting assembly 130. The second adhesive cutting assembly 130 is used to cut the adhesive tape 400 clamped by the adhesive sandwich assembly 20 so that the starting end of the adhesive tape 400 exceeds the length of the adhesive sandwich assembly 20 by a certain amount. In this way, when a new adhesive tape 400 is replaced, the length of the adhesive tape segment formed by cutting the starting end of the adhesive tape 400 is the same as the length of other adhesive tape segments to meet the adhesive application requirements.

[0056] The second rubber cutting assembly 130 includes a second rubber cutting drive 131 and a second cutter 132, wherein the second cutter 132 is connected to the second rubber cutting drive 131, and the second rubber cutting drive 131 is used to drive the second cutter 132 to move to cut the tape 400. Optionally, the second rubber cutting drive 131 is used to drive the second cutter 132 to move in a first direction, and at this time, the second cutter 132 is perpendicular to the tape 400, so as to facilitate cutting off the end of the tape 400. Specifically, during cutting, the tape 400 can be pulled manually, the adhesive clamping assembly 20 clamps the tape 400, and the second cutter 132 cuts off the end of the tape 400 between the adhesive clamping assembly 20 and the manually pulled portion. Among them, the second rubber cutting drive 131 can select a cylinder or a motor.

[0057] It is understandable that in some other implementations, the second glue cutting component 130 may also be configured in other ways, as long as the glue cutting effect can be achieved, and this is not limited here.

[0058] Another embodiment of the present application further provides a glue preparation mechanism 100 included in the above-mentioned glue application device. Since the above-mentioned glue application device has beneficial effects, the glue preparation mechanism 100 has the same beneficial effects, which will not be described in detail herein.

[0059] The working principles of the glue preparation mechanism 100 and the glue application device provided in the embodiment of the present application are as follows:

[0060] The first driving member 71 drives the moving plate 72 to move along the first direction, so that a glue assembly 20 moves to the first position. The glue pulling driving member 51 drives the clamping claw 52 to move along the second direction close to the glue assembly 20 located at the first position, and the clamping claw 52 clamps the tape 400 (working tape) clamped by the glue assembly 20. The glue pulling driving member 21 drives the glue plate to move along the first direction, and the first glue plate 22 and the second glue plate 23 move away from the loosening tape 400. The glue pulling driving member 51 drives the clamping claw 52 to move in the opposite direction along the second direction, and pulls the tape 400 out a certain distance. The glue pulling driving member 21 drives the glue plate to move again, and the first glue plate 22 and the second glue plate 23 approach the clamping tape 400. The suction cup 200 of the glue sticking mechanism absorbs the tape 400, and the first glue cutting driving member 41 drives the first cutter 42 to move along the first direction. The first cutter 42 cooperates with the suction cup 200 to cut the tape 400 to form a tape segment. The tape segment moves with the suction cup 200 to be attached to the material tape. The glue pulling action is repeated, and the suction cup 200 returns after attaching the tape segment. The first cutter 42 cooperates with the suction cup 200 again to cut the next tape segment, and this cycle is repeated until the working tape reel on the unwinding assembly 10 is unwound.

[0061] It should be noted that when the unwinding assembly 10 corresponding to the laminating assembly 20 in the first position unwinds and outputs the adhesive tape 400, a spare adhesive disc can be installed on the other laminating assembly 20, and the spare adhesive tape is inserted between the first laminating plate 22 and the second laminating plate 23. The second cutting drive member 131 drives the second cutter 132 to move, and cuts off the end of the spare adhesive tape, so that the starting end of the spare adhesive tape exceeds the position of the laminating plate by a certain amount.

[0062] When the working rubber disc is unwound, the first driving member 71 drives the moving plate 72 to move again in the first direction, so that the other glue clamping assembly 20 moves to the first position. At this time, the spare rubber disc as the working rubber disc starts to unwind according to the above steps, and is finally cut into a tape segment. This cycle is repeated to ensure continuous glue preparation of the glue preparation mechanism 100.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
