Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a glue sticking device. Background Art

[0002] During the battery production process, a gluing device is required to perform online gluing of the battery cells before they are stacked and assembled. The specific operation method is to first cut the tape into strips of appropriate size, and then stick the strips onto the large surface of the battery cells.

[0003] The working effect of the current glue sticking device is not ideal, and it has the following defects:

[0004] There is only one cutter installed on the glue sticking device, and only one glue strip can be obtained in one cut, so the cutting efficiency is relatively low:

[0006] The two cut surfaces formed by cutting are still close to each other after cutting is completed, resulting in secondary adhesion;

[0062] The present application provides a glue sticking device that can improve cutting efficiency and optimize working performance.

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] like Figure 1-Figure 4As shown, an embodiment of the present application provides a glue sticking device for online glue sticking of battery cells, which has many differences from the existing glue sticking devices. The glue sticking device of the present application mainly includes a frame 1 and a glue cutting mechanism 2, wherein the frame 1 is the supporting structure of the glue sticking device, and the glue cutting mechanism 2 and the glue separating mechanism 3, glue pressing mechanism 4 and glue sticking mechanism 5 described later are all arranged on the frame 1; the glue cutting mechanism 2 arranged on the frame 1 is used for cutting the tape (in the present application, the combined structure with the colloid and the base paper is referred to as the tape, the colloid after the base paper is separated is referred to as the part to be cut, and the small volume of colloid obtained after cutting is referred to as the cut body. In order to explain the present application scheme more clearly and accurately, the above more specific names will be used in the following content instead of "tape" The rubber cutting mechanism 2 includes a plurality of cutters, and when the rubber cutting mechanism 2 cuts the part to be cut, the plurality of cutters cut the part to be cut synchronously. For example, the rubber cutting mechanism 2 may include two identical cutters, and the two cutters are arranged in parallel. The spacing between the two cutters is the width of the cutting body. When cutting the part to be cut, the two cutters move synchronously along two parallel tracks to achieve synchronous cutting of the part to be cut. Since a cutting body can be formed by cutting between the two cutters, and at least one side of the two cutters can also be cut to form a cutting body, multiple cutting bodies can be obtained through one rubber cutting operation.

[0065] Since the above-mentioned gluing device can obtain multiple cut bodies through one cutting operation, compared with the existing gluing device which has only one cutter and obtains only one cut body through one cutting operation, the cutting efficiency can be improved. With the improvement of cutting efficiency, the gluing efficiency can also be improved, thereby optimizing the working performance of the gluing device. In addition, the gluing device provided by the present application also has more advantages through other improvements, which will be explained one by one in the following content.

[0066] For the rubber cutting mechanism 2, the moving trajectory of the cutter is further inclined relative to the plane where the part to be cut is located. By moving the cutter along the inclined moving trajectory, while the cutter moves relative to the part to be cut, the cutter is also raised and lowered relative to the part to be cut, so that different parts of the blade can be brought into contact with the part to be cut for cutting, thereby avoiding the situation where the same part of the blade is always cut, resulting in uneven wear of the cutter, and extending the working life of the cutter. In addition, in order to achieve this purpose, the part to be cut can also be inclined on the premise of meeting the cutting requirements, so that different parts of the blade can be brought into contact with the part to be cut during the cutting process.

[0067] like Figure 1 and Figure 2As shown, the glue-applying device provided by the present application also includes a glue-applying mechanism 3 arranged on the frame 1, and the glue-applying mechanism 3 can make the multiple cutting bodies move away from each other in the horizontal direction and / or be dislocated in the vertical direction. After the cutting is completed, if the multiple cutting bodies or the cutting bodies and the remaining parts to be cut still maintain the same position before cutting, due to the small slit, there will be a secondary adhesion, which will bring inconvenience to the subsequent glue-applying. Based on this, the glue-applying device provided by the present application is additionally provided with a glue-applying mechanism 3, and this glue-applying mechanism 3 can make the multiple cutting bodies or the cutting bodies and the remaining parts to be cut move away from each other in the horizontal direction and / or be dislocated in the vertical direction, thereby reducing or even eliminating the occurrence of secondary adhesion, bringing convenience to the subsequent glue-applying, and further improving the working performance of the glue-applying device.

[0068] Further, such as Figure 1 and Figure 4 As shown, a glue pressing mechanism 4 is provided on the frame 1, and the glue pressing mechanism 4 fixes the part to be cut by pressing the part of the tape to be cut against the glue dispensing mechanism 3. In this structure, on the one hand, a glue pressing mechanism 4 is provided on the frame 1, so that the glue pressing mechanism 4 is integrated with the glue sticking device, so that there is no need to use an independent glue pressing device to cooperate with the glue sticking device, which can not only reduce costs, but also simplify the structure by optimizing the structure, making the glue sticking device more functional; on the other hand, the glue pressing mechanism 4 cooperates with the glue dispensing mechanism 3, and the support member cooperating with the glue pressing mechanism 4 can be omitted, which not only simplifies the structure, but also improves the glue pressing effect and the glue dispensing effect through the cooperation of the two, making the working performance of the glue sticking device more prominent.

[0069] like Figure 2As shown, the glue separation mechanism 3 includes: a first glue supporting plate 301, which is arranged close to the glue stripping plate 8 of the glue laminating device to receive the part to be cut after the glue stripping plate 8 is peeled off the base paper, and there is a first gap between the first glue supporting plate 301 and the glue stripping plate 8 for one of the multiple cutters to pass through; a second glue supporting plate 302, which is arranged on the side of the first glue supporting plate 301 away from the glue stripping plate 8 to receive the part to be cut after the glue stripping plate 8 is peeled off the base paper, and there is a second gap between the first glue supporting plate 301 and the first glue supporting plate 301 for another of the multiple cutters to pass through; a glue separation driving component 303, which is arranged on the frame 1, and can drive one of the first glue supporting plate 301 and the second glue supporting plate 302 to move away from the other in the horizontal direction and / or be displaced in the vertical direction. In this structure, since the first rubber supporting board 301 is arranged close to the rubber stripping board 8, after the adhesive tape passes through the rubber stripping board 8 to separate the adhesive and the base paper, the part to be cut (i.e. the adhesive after the base paper is peeled off) will cross the first gap and move to the first rubber supporting board 301 driven by the unseparated adhesive tape. As it continues to move, it will pass through the first rubber supporting board 301 and cross the second gap and then move to the second rubber supporting board 302, so that the part to be cut is laid on the first rubber supporting board 301 and the second rubber supporting board 302. In order to facilitate the movement of the part to be cut and the subsequent glue pressing and cutting operations, it is preferably arranged so that the first rubber supporting board 301 and the second rubber supporting board 302 are flush with the rubber stripping board 8. In the subsequent glue cutting process, the two cutters move along the first gap and the second gap respectively to cut two cutting bodies, and the two cutting bodies are respectively located on the first glue support plate 301 and the second glue support plate 302, and the two cutting seams are respectively aligned with the first gap and the second gap. After that, the glue separation driving component 303 can drive one of the first glue support plate 301 and the second glue support plate 302 to move away from the other in the horizontal direction and / or be displaced in the vertical direction, so that the distance between the multiple cutting bodies or between the cutting body and the remaining part to be cut is increased to achieve glue separation and avoid secondary adhesion.

[0070] In this glue separation process, it is preferred that the glue separation driving component 303 drives the first glue support plate 301 to move. Since the first glue support plate 301 is located between the glue stripping plate 8 and the second glue support plate 302, the first glue support plate 301 can be moved to separate the cutting body in the middle from the other cutting body on one side thereof and the remaining part to be cut on the other side thereof. In this way, only one glue separation driving component 303 is required and one component is moved to achieve glue separation, which has a simpler structure and is more convenient to operate. Alternatively, multiple glue separation driving components 303 can be provided to drive the first glue support plate 301 and the second glue support plate 302 to move respectively to achieve the separation of the two cutting bodies from each other and the remaining part to be cut. At the same time, in order to make the structure of the glue sticking device more compact and avoid interference with other components, it is preferred that the moving direction of the first glue support plate 301 and / or the first glue support plate 301 is perpendicular to the moving direction of the part to be cut, that is, the first glue support plate 301 and / or the first glue support plate 301 are displaced in the vertical reverse direction. Specifically, the glue dispensing driving component 303 is preferably a cylinder, or may also be a motor, a hydraulic cylinder, etc.

[0071] On the basis of setting the glue dispensing mechanism 3, as Figure 2 As shown, the glue dispensing mechanism 3 also includes a sensor 304, and the sensor 304 is set on the second glue supporting plate 302 to detect the size of the part to be cut. As mentioned above, the part to be cut will move to the first glue supporting plate 301 and the second glue supporting plate 302 in sequence, and there is a first gap aligned with the slit between the first glue supporting plate 301 and the glue stripping plate 8, and there is a second gap aligned with another slit between the second glue supporting plate 302 and the first glue supporting plate 301, so by controlling the position of the part to be cut on the second glue supporting plate 302, the size of the cut body can be automatically and more accurately controlled. Therefore, by setting the sensor 304 on the second supporting plate to detect the position of the part to be cut, the automatic control of the cutting size can be achieved to improve the cutting accuracy. Specifically, this sensor 304 can be an optical fiber sensor, a Hall sensor, a limit switch, etc., and the distance between its setting position on the second glue supporting plate 302 and the second gap is equal to the distance between the first gap and the second gap, that is, the distance between the sensor 304 and the second gap is the same as the width of the cut body.

[0072] like Figure 2As shown, at least one of the first rubber supporting board 301 and the second rubber supporting board 302 is provided with an air suction hole 305, and the air suction hole 305 absorbs the part to be cut on at least one of the first rubber supporting board 301 and the second rubber supporting board 302 by suction, so that the part to be cut is tightly and evenly attached and laid flat on the first rubber supporting board 301 and / or the second rubber supporting board 302, so as to further improve the cutting accuracy. Preferably, the first rubber supporting board 301 and the second rubber supporting board 302 are both provided with an air suction hole 305, and a plurality of air suction holes 305 are evenly distributed on the first rubber supporting board 301 and the second rubber supporting board 302, so as to improve the laying effect of the part to be cut on the first rubber supporting board 301 and the second rubber supporting board 302.

[0073] like Figure 2 As shown, the glue dispensing mechanism 3 also includes a blowing component 306, which can blow air to at least one of the first glue supporting plate 301 and the second glue supporting plate 302, so that the part to be cut is attached to at least one of the first glue supporting plate 301 and the second glue supporting plate 302. The function of this blowing component 306 is also to make the part to be cut better laid on the first glue supporting plate 301 and / or the second glue supporting plate 302, so as to avoid the part to be cut from warping up and affecting the adsorption effect of the suction hole 305. Specifically, the blowing component 306 includes an air duct arranged on the frame 1, and a plurality of air nozzles are arranged on the air duct at equal intervals. The air duct is staggered at the top of the first glue supporting plate 301 and the second glue supporting plate 302, so as to avoid interference with the glue pressing mechanism 4 while allowing the gas ejected from the air nozzle to purge the part to be cut on the first glue supporting plate 301 and / or the second glue supporting plate 302. Specifically, since the end of the part to be cut before cutting is located on the second rubber supporting plate 302, the probability and degree of warping are greater, so it is preferred that the blowing component 306 mainly blows the second rubber supporting plate 302 and the part to be cut thereon.

[0074] In this application, if Figure 3As shown, the rubber cutting mechanism 2 includes: a rubber cutting guide rail 201, which is tilted relative to the first rubber supporting plate 301 on the frame 1; a first cutter 202, which is slidably arranged on the rubber cutting guide rail 201 through a slider, and cuts the tape by sliding in the first gap; a second cutter 203, which is slidably arranged on the rubber cutting guide rail 201 through a slider, and cuts the tape by sliding in the second gap; and a rubber cutting drive component 204, which is arranged on the frame 1 and can drive the slider to slide on the rubber cutting guide rail 201. Among them, by making the first rubber supporting plate 301 and the second rubber supporting plate 302 horizontally arranged on the frame 1, and the rubber cutting guide rail 201 tilted relative to the first rubber supporting plate 301, the cutter can gradually move up or down relative to the part to be cut when moving on the rubber cutting guide rail 201 to cut the part to be cut, so that different parts of the blade contact the part to be cut for cutting. The first cutter 202 and the second cutter 203 are preferably isosceles triangle cutters arranged in parallel with each other and having inclined blades, and the two waists of the isosceles triangle are blades, so as to improve the cutting effect and convenience of the local area to be cut. When arranged on the frame 1, the glue cutting mechanism 2 is located at the bottom of the glue dispensing mechanism 3, so that the first cutter 202 and the second cutter 203 can pass through the first gap and the second gap from the bottom respectively, to ensure the normal cutting of the local area to be cut on the first rubber supporting plate 301 and the second rubber supporting plate 302, when the cutting operation is not performed, the first cutter 202 and the second cutter 203 are respectively located at the ends of the first gap and the second gap, that is, the first cutter 202 and the second cutter 203 are located on the side of the moving direction of the local area to be cut, so as to avoid blocking the movement of the local area to be cut. In addition, the glue cutting mechanism 2 is arranged at the bottom of the glue dispensing mechanism 3, which can also avoid interference with the glue pressing mechanism 4. The glue cutting drive component 204 is preferably a cylinder, or can also be a motor, a hydraulic cylinder, etc., and its driving stroke is greater than the cutting distance of the local area to be cut.

[0075] See also Figure 4The glue pressing mechanism 4 adapted to the glue separating mechanism 3 includes: a first pressing block 401, which can be aligned with the glue stripping plate 8 and press the tape onto the glue stripping plate 8; a second pressing block 402, which can be aligned with the first glue supporting plate 301 to press the first area to be cut onto the first glue supporting plate 301; a third pressing block 403, which can be aligned with the second glue supporting plate 302 to press the second area to be cut onto the second glue supporting plate 302. Before cutting the glue, the first pressing block 401 is first pressed against the adhesive tape on the glue stripping plate 8, the second pressing block 402 is pressed against the first area of ​​the part to be cut on the first glue supporting plate 301 (this first area becomes a cutting body after the cutting is completed), and the third pressing block 403 is pressed against the second area of ​​the part to be cut on the second glue supporting plate 302 (this second area becomes another cutting body after the cutting is completed), and then the first cutter 202 and the second cutter 203 are respectively passed through the first gap and the second gap to achieve cutting, and there is a gap between the first pressing block 401 and the second pressing block 402 to allow the first cutter 202 to enter and move therein, and there is also a gap between the second pressing block 402 and the third pressing block 403 to allow the second cutter 203 to enter and move therein, so as to ensure smooth cutting. This glue pressing mechanism 4 having a first pressing block 401, a second pressing block 402 and a third pressing block 403 can press the part to be cut on both sides of multiple cutting positions, thereby avoiding accidental movement of the part to be cut during the cutting process to the greatest extent, thereby better ensuring the cutting accuracy, and its structure is relatively simple, which is convenient for integration on the frame 1.

[0076] On the basis that the glue pressing mechanism 4 can press the part to be cut, the present application preferably enables the glue pressing mechanism 4 to cooperate with the glue sticking mechanism 5 described later to realize glue feeding. Specifically, the second pressing block 402 and the third pressing block 403 are both provided with suction cups that can absorb the cutting body, and when the suction cups absorb the cutting body, the second pressing block 402 and the third pressing block 403 are separated in the horizontal direction and / or misaligned in the vertical direction. Since the glue pressing mechanism 4 needs to press the part to be cut before cutting, after the suction cups are provided on the second pressing block 402 and the third pressing block 403, it can absorb the part to be cut while pressing the part to be cut, so that after the cutting is completed, the second pressing block 402 and the third pressing block 403 can be connected to the two cutting bodies respectively through the absorption of the suction cups, and then with the action of the glue sticking mechanism 5, the glue pressing mechanism 4 can carry the cutting body from the top of the glue dispensing mechanism 3 to the position of the battery cell, and then transfer the cutting body to the battery cell for glue sticking operation. Among them, on the one hand, using the glue pressing mechanism 4 to realize glue feeding can avoid setting up a special glue feeding mechanism, so that the structure of the glue sticking device is simplified; on the other hand, in the process of glue feeding, it is also preferred that the second pressing block 402 and the third pressing block 403 are separated in the horizontal direction and / or displaced in the vertical direction, so that the separation state of the two cutting bodies can be maintained to avoid secondary adhesion from occurring again, so that the glue pressing mechanism 4 can have the functions of glue pressing, glue feeding and glue separation. Corresponding to the movement mode of the first glue supporting plate 301 and the second glue supporting plate 302, the present application also preferably displaces the second pressing block 402 and the third pressing block 403 in the vertical direction. At the same time, in order to ensure the glue pressing effect and avoid affecting the glue pressing due to the upper and lower dislocation, it is preferred that at least one of the second pressing block 402 and the third pressing block 403 can be telescopically displaced and reset by the drive of the spring. In addition, the connection between the second pressing block 402 and the third pressing block 403 and the cutting body can also adopt other structures other than the suction cup, such as clamping claws, suction holes, etc.

[0077] like Figure 1 and Figure 4As shown, the glue sticking device provided by the present application also includes a glue sticking mechanism 5, which includes: a support frame 501, which is arranged across the production line of the battery cell; a Y-axis moving mechanism 502, which is arranged on the support frame 501; a Z-axis moving mechanism 503, which is arranged on the Y-axis moving mechanism 502 and moves driven by the Y-axis moving mechanism 502; an X-axis moving mechanism 504, which is arranged on the Z-axis moving mechanism 503 and moves driven by the Z-axis moving mechanism 503 (the Y-axis, Z-axis and X-axis are respectively the Y-axis, Z-axis and X-axis in the spatial rectangular coordinate system); wherein, the glue pressing mechanism 4 is arranged on the X-axis moving mechanism 504, and moves driven by the X-axis moving mechanism 504, so that the glue pressing mechanism 4 can be aligned with the glue dispensing mechanism 3 to press the part to be cut, and the glue pressing mechanism 4 can be aligned with the battery cell to stick the cut body on the battery cell. In this structure, the support frame 501 is a component of the frame 1, and it can be a separate structure or an integrated structure with other parts of the frame 1. By setting up this support frame 501 that crosses the production line, the glue pressing mechanism 4 and the cutting body transported by it can be moved to the position of the battery cell on the production line under the drive of the Y-axis moving mechanism 502, the Z-axis moving mechanism 503 and / or the X-axis moving mechanism 504; any of the Y-axis moving mechanism 502, the Z-axis moving mechanism 503 and the X-axis moving mechanism 504 is composed of a guide rail, a slider slidably set on the guide rail, and a driving component (such as a cylinder or a motor, etc.) that drives the slider to move on the guide rail. The Z-axis moving mechanism 503 is set on the slider of the Y-axis moving mechanism 502, and the X-axis moving mechanism 504 is set on the slider of the Z-axis moving mechanism 503. The difference is that the guide rails of the three are respectively set along the Y-axis, Z-axis and X-axis, so that the glue pressing mechanism 4 set on the slider of the X-axis moving mechanism 504 can be moved to any position in space, thereby better meeting the glue sticking requirements.

[0078] Based on the above structure, Figure 1As shown, the glue-applying device provided by the present application also includes: a reeling mechanism 6, which is arranged on the frame 1 and is used to install a tape roll; the above-mentioned glue stripping plate 8 is arranged on the frame 1, and can separate the glue and the base paper of the tape drawn out from the reeling mechanism 6; a recovery roller 13, which is rotatably arranged on the frame 1, and can wind the base paper separated by the glue stripping plate 8; a pulling roller 9 and a pressure roller 11, which are rotatably arranged on the frame 1 and are located between the glue stripping plate 8 and the recovery roller 13, so as to clamp and pull the base paper to make the tape drawn out from the reeling mechanism 6; a pulling drive component 10 (the pulling drive component 10 is, for example, a motor), which is arranged on the frame 1 and is at least used to drive the pulling roller 9 to rotate; a plurality of guide rollers 7 are rotatably arranged on the frame 1, and are respectively located between the reeling mechanism 6 and the glue stripping plate 8, and between the glue stripping plate 8 and the pulling roller 9, so as to realize the change of direction of the tape or the base paper. This part of the structure is used to realize the setting, leading, stripping, driving and recycling of the tape. It realizes the online gluing of the battery cell through the auxiliary glue cutting mechanism 2, the glue separating mechanism 3, the glue pressing mechanism 4 and the glue sticking mechanism 5.

[0079] Based on the above structure, the specific working process of the glue sticking device provided by the present application is as follows:

[0080] First, preparation work is performed: the tape roll is set on the unwinding mechanism 6 so that the entire tape roll can rotate on the frame 1 to lead out the tape, and the end of the led tape (this end only includes the base paper, and there is no glue on the base paper) first passes around the guide roller 7 between the unwinding mechanism 6 and the stripping plate 8 to achieve steering, and then the tape passes through the stripping plate 8 and is turned to the guide roller 7 located at the bottom of the stripping plate 8 at the end of the stripping plate 8 close to the first supporting plate 301. The end of the tape is guided by the guide roller 7 between the stripping plate 8 and the pulling roller 9, so that the end of the tape passes between the pulling roller 9 and the pressure roller 11, and is finally fixed on the recovery roller 13;

[0081] Then the rubber cutting and gluing work is carried out: the pressure roller driving component 12 is started (the pressure roller driving component 12 is, for example, a cylinder), so that the pressure roller 11 is close to the drawing roller 9 until the end of the tape is clamped with the drawing roller 9, and then the drawing driving component 10 is started. The drawing driving component 10 drives the drawing roller 9 to rotate, so as to continuously pull the tape out of the unwinding mechanism 6. At the same time, the drawing driving component 10 drives the recovery roller 13 to rotate through the synchronous belt, and the base paper separated by the stripping plate 8 is wound onto the recovery roller 13; the pulled tape is moved When the stripping plate 8 moves to the end portion close to the first adhesive supporting plate 301, since the base paper has turned and the adhesive itself has a certain rigidity, the adhesive (i.e. the part to be cut) will separate from the base paper and continue to move in the same direction to the first adhesive supporting plate 301 and the second adhesive supporting plate 302; when the sensor 304 arranged on the second adhesive supporting plate 302 detects that the part to be cut has moved into place, the material pulling driving component 10 is turned off, the material pulling roller 9 stops pulling the base paper to stop the tape from being drawn out, and the part to be cut also stops on the first adhesive supporting plate 302. The glue plate 301 and the second glue supporting plate 302 are placed on the glue plate 301; then the glue pressing mechanism 4 is driven by the glue sticking mechanism 5 to move to the top of the glue dispensing mechanism 3, and the first pressing block 401 presses the adhesive tape on the glue stripping plate 8, the second pressing block 402 presses the first glue cutting area on the first glue supporting plate 301, and the third pressing block 403 presses the second glue cutting area on the second glue supporting plate 302; after pressing, the glue cutting driving component 204 is started, and the first cutter 202 and the second cutter 203 are driven. Move in the first gap and the second gap to cut the part to be cut, and obtain two cutting bodies respectively located on the first glue supporting plate 301 and the second glue supporting plate 302; then the glue separation driving component 303 is started to drive the first glue supporting plate 301 to move up and the second pressing block 402 to contract to achieve glue separation; finally, the Y-axis moving mechanism 502, the Z-axis moving mechanism 503 and / or the X-axis moving mechanism 504 drive the glue pressing mechanism 4 and the adsorbed cutting body to move, so as to transfer the cutting body to the battery cell for gluing.

[0082] In summary, the gluing device provided in the present application achieves improved cutting efficiency by setting up multiple cutters; by allowing the cutters to move along an inclined moving trajectory, severe wear on the same part of the blade is avoided, thereby extending the working life of the cutters; by setting up a glue separation mechanism 3, secondary adhesion after cutting is avoided; and by setting the glue pressing mechanism 4 on the frame 1, the integration of the glue pressing function is achieved, the structure is simplified, and the production cost is reduced.
