Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, and particularly relates to a glue coating device and glue coating equipment. Background Art

[0002] In industrial production, applying glue to a continuous tape is a common process, which is widely used in many fields such as packaging cartons and battery electrodes. To achieve this process, glue coating devices are widely used in production lines.

[0003] There is a conventional glue coating device, which includes a glue coating roller, a movable roller and a cylinder. The glue coating roller is used to coat glue on the surface of the tape, and the tape is arranged outside the movable roller. The cylinder, as a driving component, drives the movable roller to approach or move away from the glue coating roller through telescopic movement, so that the tape contacts and separates from the glue coating roller, thereby controlling the start and stop of glue coating.

[0004] However, since the telescopic movement of the cylinder takes a certain amount of time to complete, this glue coating device has a problem of slow response speed when switching between the glue coating state and the stop glue coating state. Summary of the Utility Model

[0005] The main object of the utility model is to provide a glue coating device and glue coating equipment, aiming to improve the response speed of the glue coating device when switching between the glue coating state and the stop glue coating state.

[0006] To achieve the above object, the glue coating device proposed by the utility model includes:

[0007] A bracket;

[0008] A glue coating roller rotatably arranged on the bracket;

[0009] A swing assembly having opposite first and second ends, the first end being rotatably arranged on the bracket, and the second end extending to one side of the glue coating roller;

[0010] A movable roller arranged at the second end and parallel to the glue coating roller, with the tape wound around the outside of the movable roller; and

[0011] A first driving mechanism drivingly connected to the first end to rotate the second end around the first end, so that the movable roller has a glue coating position and a rest position;

[0012] Wherein, at the glue coating position, the movable roller approaches the glue coating roller so that the tape fits against the glue coating roller; at the rest position, the movable roller moves away from the glue coating roller so that the tape separates from the glue coating roller.

[0013] In one embodiment, the first driving mechanism includes:

[0014] A servo motor, disposed on the bracket; and

[0015] A transmission assembly, drivingly connected to the output end of the servo motor and the first end.

[0016] In one embodiment, the transmission assembly includes:

[0017] A first pulley, disposed on the output end of the servo motor;

[0018] A second pulley, disposed on the first end; and

[0019] A timing belt, wound around the outside of the first pulley and the second pulley and meshingly connected to the first pulley and the second pulley.

[0020] In one embodiment, the gluing device further includes a detection assembly, which is electrically connected to the first driving mechanism and is used to detect whether the material tape moves.

[0021] In one embodiment, the detection assembly includes:

[0022] A detection roller, disposed parallel to the movable roller, and the material tape is wound around the outside of the movable roller and the detection roller; and

[0023] An encoder, disposed at one end of the detection roller and electrically connected to the first driving mechanism, for detecting whether the detection roller rotates.

[0024] In one embodiment, the swing assembly includes:

[0025] Two swing members, spaced apart, having opposite third ends and fourth ends, wherein at least one of the third ends is rotatably connected to the bracket, and the movable roller is rotatably disposed between the two fourth ends; and

[0026] A support member, connecting the two swing members.

[0027] In one embodiment, the gluing device further includes a guide roller, which is rotatably disposed at the first end and is disposed parallel to the movable roller, and the material tape is wound around the outside of the guide roller and the movable roller.

[0028] In one embodiment, at the gluing position, the movable roller and the guide roller are located on both sides of the gluing roller.

[0029] In one embodiment, the gluing device further includes a second driving mechanism, which is disposed on the bracket and drivingly connects the gluing roller.

[0030] The present utility model also provides a gluing device, including:

[0031] A roller conveying device for driving a strip to move or stop; and

[0032] The above-mentioned glue coating device is arranged on the roller conveying device.

[0033] The glue coating device in the technical solution of the present utility model includes a bracket, a glue coating roller, a swing assembly, a movable roller and a first driving mechanism. The first driving mechanism is drivingly connected to the first end of the swing assembly, so that the swing assembly rotates around the first end, which also makes the second end of the swing assembly swing around the first end, thereby making the movable roller arranged at the second end of the swing assembly swing around the first end of the swing assembly. When the movable roller swings to the glue coating position, the strip wound around the movable roller is attached to the glue coating roller, and the glue coating roller performs a glue coating operation on the strip. As the strip moves, the glue coating roller continuously coats the strip; when the movable roller swings away from the glue coating position to the rest position, the strip is separated from the glue coating roller, so that the glue coating roller cannot coat the strip, avoiding the problem of abnormal glue spots on the strip caused by the strip being attached to the glue coating roller when no glue coating is required. Since the movable roller is arranged at the second end of the swing assembly, and the swing center of the swing assembly is the first end, the angular velocities of the first end and the second end are the same, but the linear velocity of the second end is greater than that of the first end. Therefore, even a slight rotation of the first end will cause a large swing of the second end, thereby quickly moving the movable roller and driving the strip to quickly attach to or separate from the glue coating roller, improving the response speed of the glue coating device when switching between the glue coating state and the stop glue coating state, avoiding the problems that the strip has not been fully attached to the glue coating roller when glue coating is required and the strip has not been fully separated from the glue coating roller when no glue coating is required, and further improving the glue coating quality and reducing abnormal glue spots.

[0055] The present utility model provides a glue coating device.

[0056] Please refer to Figure 1 、 Figure 4 and Figure 5 , Figure 1 which are the structural schematic diagrams of an embodiment of the glue coating device provided by the present utility model Figure 1 , Figure 4 which are the structural schematic diagrams of an embodiment of the glue coating device provided by the present utility model Figure 2 , Figure 5 which are the structural schematic diagrams of an embodiment of the glue coating device provided by the present utility model Figure 3 。

[0057] In an embodiment of the present utility model, the glue coating device includes:

[0058] A bracket 100;

[0059] A glue coating roller 200, rotatably arranged on the bracket 100;

[0060] A swing assembly 300, having opposite first and second ends, the first end being rotatably arranged on the bracket 100 and the second end extending to one side of the glue coating roller 200;

[0061] The movable roller 400 is provided at the second end and is arranged in parallel with the glue - applying roller 200, and the material tape 10 is wound around the outside of the movable roller 400; and

[0062] The first driving mechanism 500 is drivingly connected to the first end to enable the second end to rotate around the first end, so that the movable roller 400 has a glue - applying position and a rest position;

[0063] Wherein, at the glue - applying position, the movable roller 400 approaches the glue - applying roller 200 so that the material tape 10 is attached to the glue - applying roller 200; at the rest position, the movable roller 400 is away from the glue - applying roller 200 so that the material tape 10 is separated from the glue - applying roller 200.

[0064] The glue - applying device in the technical solution of the present utility model includes a bracket 100, a glue - applying roller 200, a swing assembly 300, a movable roller 400 and a first driving mechanism 500. The first driving mechanism 500 is drivingly connected to the first end of the swing assembly 300, so that the swing assembly 300 rotates around the first end, that is, the second end of the swing assembly 300 swings around the first end, thereby enabling the movable roller 400 provided at the second end of the swing assembly 300 to swing around the first end of the swing assembly 300. When the movable roller 400 swings to the glue - applying position, the material tape 10 wound around the movable roller 400 is attached to the glue - applying roller 200, and the glue - applying roller 200 performs a glue - applying operation on the material tape 10. As the material tape 10 moves, the glue - applying roller 200 continuously applies glue to the material tape 10; when the movable roller 400 swings away from the glue - applying position to the rest position, the material tape 10 is separated from the glue - applying roller 200, so that the glue - applying roller 200 cannot apply glue to the material tape 10, avoiding the problem of abnormal glue spots on the material tape 10 caused by the material tape 10 being attached to the glue - applying roller 200 when no glue - applying is required. Since the movable roller 400 is provided at the second end of the swing assembly 300, and the swing center of the swing assembly 300 is the first end, the angular velocities of the first end and the second end are the same, but the linear velocity of the second end is greater than that of the first end. Therefore, even a slight rotation of the first end will cause a large - amplitude swing of the second end, so that the movable roller 400 moves quickly, driving the material tape 10 to quickly attach to or separate from the glue - applying roller 200, improving the response speed of the glue - applying device when switching between the glue - applying state and the non - glue - applying state, avoiding the problems that the material tape 10 has not been fully attached to the glue - applying roller 200 when glue - applying is required and the material tape 10 has not been fully separated from the glue - applying roller 200 when no glue - applying is required, thereby improving the glue - applying quality and reducing abnormal glue spots.

[0065] In an embodiment, the first driving mechanism 500 includes:

[0066] A servo motor 510, which is provided on the bracket 100; and

[0067] A transmission assembly 520, which is drivingly connected to the output end of the servo motor 510 and the first end.

[0068] Refer toFigure 1 In the embodiment of the present utility model, the first driving mechanism 500 includes a servo motor 510 and a transmission component 520. The servo motor 510 is arranged on the bracket 100 and is used for providing power output. The transmission component 520 is in transmission connection with the output end and the first end of the servo motor 510, and is used for transmitting the power of the servo motor 510 to the swing component 300. The servo motor 510 has a fast response speed, which further improves the response speed of the gluing device when switching between the gluing state and the non-gluing state. Moreover, the servo motor 510 has high precision, which improves the positioning precision and repeated positioning precision of the swing component 300 during swinging. Thus, the positioning precision and repeated positioning precision of the movable roller 400 when switching between the gluing position and the rest position are improved, and further the gluing quality is improved and abnormal glue spots are reduced. Arranging the transmission component 520 for transmission can reduce the layout difficulty of the first driving mechanism 500 and facilitate the layout of the first driving mechanism 500. The transmission component 520 can be implemented in various forms such as gear transmission and belt transmission.

[0069] In one embodiment, the transmission component 520 includes:

[0070] A first pulley 522 arranged at the output end of the servo motor 510;

[0071] A second pulley 523 arranged at the first end; and

[0072] A synchronous belt 521 wound around the outside of the first pulley 522 and the second pulley 523 and meshed with the first pulley 522 and the second pulley 523.

[0073] Combined with Figure 1 and Figure 2 , in the embodiment of the present utility model, the transmission component 520 includes a first pulley 522, a second pulley 523 and a synchronous belt 521. The first pulley 522 is fixed at the output end of the servo motor 510. When the servo motor 510 rotates, the first pulley 522 rotates accordingly. The second pulley 523 is arranged at the first end of the swing component 300 and is connected to the first pulley 522 through the synchronous belt 521, so as to realize the transmission and speed increase of power. The transmission component 520 is implemented in the form of belt transmission. The meshed connection between the synchronous belt 521 and the pulleys ensures the accuracy of transmission, improves the transmission precision, and thus improves the positioning precision and repeated positioning precision of the swing component 300 during swinging; moreover, the maintenance of the synchronous belt 521 transmission is relatively simple, the replacement is convenient, and the maintenance cost and downtime are reduced.

[0074] In one embodiment, the gluing device further includes a detection component 600. The detection component 600 is electrically connected to the first driving mechanism 500, and the detection component 600 is used for detecting whether the material tape 10 moves.

[0075] Refer to Figure 1, in an embodiment of the present utility model, the strip 10 moves intermittently. When the strip 10 moves, glue application operation needs to be carried out, and the movable roller 400 is located at the glue application position; when the strip 10 stops moving, glue application operation is not required, and the movable roller 400 is located at the rest position. The detection component 600 can be a photoelectric sensor, an encoder 620 or a limit switch, etc., and is used to detect whether the strip 10 moves. When the strip 10 stops moving, the detection component 600 will feedback the corresponding signal to the first driving mechanism 500, so that the first driving mechanism 500 drives the swing component 300 to swing, and then the movable roller 400 is switched to the rest position; when the strip 10 continues to move, the detection component 600 feedbacks the corresponding signal to the first driving mechanism 500 again, so that the first driving mechanism 500 drives the swing component 300 to swing in the reverse direction, and then the movable roller 400 is switched to the glue application position. By setting the detection component 600, automatic control of the first driving mechanism 500 can be realized, so that the movable roller 400 automatically switches between the glue application position and the rest position according to whether the strip 10 moves, thereby improving production efficiency and reducing product defects.

[0076] In one embodiment, the detection component 600 includes:

[0077] A detection roller 610, arranged in parallel with the movable roller 400, and the strip 10 is wound around the outside of the movable roller 400 and the detection roller 610; and

[0078] An encoder 620, arranged at one end of the detection roller 610 and electrically connected to the first driving mechanism 500, and is used to detect whether the detection roller 610 rotates.

[0079] Referring to Figure 1 , in an embodiment of the present utility model, the detection component 600 includes a detection roller 610 and an encoder 620. The strip 10 is wound around the outside of the detection roller 610. Due to the action of friction, when the strip 10 moves normally, the detection roller 610 will rotate accordingly; if the strip 10 stops moving, the detection roller 610 will also stop rotating accordingly. The encoder 620 can convert mechanical motion into an electrical signal, generate a corresponding electrical signal by detecting whether the detection roller 610 rotates, and transmit it to the first driving mechanism 500. By the cooperation of the detection roller 610 and the encoder 620, detecting the movement of the strip 10 is converted into detecting the rotation of the detection roller 610, and the implementation method is simpler and the detection accuracy is improved.

[0080] In one embodiment, the swing component 300 includes:

[0081] Two swing members 310 are arranged at intervals, having opposite third ends and fourth ends, and at least one of the third ends is rotatably connected to the bracket 100, and the movable roller 400 is rotatably arranged between the two fourth ends; and

[0082] The support member 320 connects the two swing members 310.

[0083] Combine Figures 1 to 3 , in an embodiment of the present utility model, the swing assembly 300 includes two swing members 310 and a support member 320 connecting the two swing members 310. The movable roller 400 is arranged between the two swing members 310. The structure of the entire swing assembly 300 is relatively simple, facilitating manufacturing and maintenance, and reducing production costs. Specifically in this embodiment, the support member 320 is arranged on the side of the swing member 310 away from the glue application roller 200, avoiding interference between the support member 320 and the glue application roller 200 when the movable roller 400 is in the glue application position.

[0084] In an embodiment, the glue application device further includes a guide roller 700. The guide roller 700 is rotatably arranged at the first end and is parallel to the movable roller 400. The material tape 10 is wound around the outside of the guide roller 700 and the movable roller 400.

[0085] Refer to Figures 3 to 5 , in an embodiment of the present utility model, the glue application device further includes a guide roller 700. The guide roller 700 is rotatably arranged at the first end. Specifically, the guide roller 700 is rotatably arranged between the third ends of the two swing members 310. The guide roller 700 provides more support for the material tape 10, ensuring that the material tape 10 remains stable during movement, reducing the jitter of the material tape 10 during the glue application process. Through the cooperation of the movable roller 400 and the guide roller 700, the material tape 10 is more stable when it fits with the glue application roller 200, thereby ensuring the consistency and uniformity of the glue application.

[0086] In an embodiment, at the glue application position, the movable roller 400 and the guide roller 700 are located on both sides of the glue application roller 200.

[0087] Refer to Figure 5 , in an embodiment of the present utility model, when the movable roller 400 is in the glue application position, the movable roller 400 and the guide roller 700 are located on both sides of the glue application roller 200, which is beneficial to ensuring that the material tape 10 wound around the movable roller 400 and the guide roller 700 fits tightly with the glue application roller 200, so that the glue application roller 200 can evenly apply glue to the material tape 10; on the other hand, through the support of the guide roller 700 and the movable roller 400 on both sides of the glue application roller 200, the material tape 10 remains stable during glue application, reducing problems such as glue application deviation and uneven glue application, and improving the precision of glue application. Specifically in this embodiment, an avoidance opening 311 is further provided on the side of the swing member 310 facing the glue application roller 200. When the movable roller 400 is in the glue application position, the swing member 310 avoids the glue application roller 200 through the avoidance opening 311, avoiding interference between the swing member 310 and the glue application roller 200.

[0088] In an embodiment, the glue application device further includes a second driving mechanism 800. The second driving mechanism 800 is arranged on the bracket 100 and is drivingly connected to the glue application roller 200.

[0089] Referring to Figure 1 , in the embodiment of the present utility model, the glue coating device further includes a second driving mechanism 800. The second driving mechanism 800 is arranged on the bracket 100 and is drivingly connected to the glue coating roller 200, providing the power for the rotation of the glue coating roller 200 to ensure that the glue coating roller 200 can uniformly coat the glue on the strip 10 at an appropriate speed and pressure. The second driving mechanism 800 can be implemented in various forms such as a motor combined with gear transmission, belt transmission, etc. Specifically in this embodiment, the second driving mechanism 800 drives the glue coating roller 200 in the way of a motor combined with a synchronous belt 521, which has the same form as the first driving mechanism 500, reducing the types of components of the glue coating device and lowering the manufacturing and maintenance difficulties.
