Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a glue feeding device, glue coating equipment and glue coating system. Background Technology

[0002] In related technologies, adhesive tape is manually pulled out and applied to the workpiece. When the workpiece rotates, the tape is pulled, causing the tray carrying the tape to rotate and thus applying the tape. However, this manual application method results in significant fluctuations in the initial position of the tape on the workpiece, and it is difficult to manually control the adhesion and tape delivery amount, leading to poor adhesion between the workpiece and the tape and low tape application efficiency. Summary of the Invention

[0003] In view of this, a first aspect of the present application aims to provide a glue feeding device to improve the bonding effect between the workpiece and the tape, and to improve the quality of the adhesive coating. The glue feeding device includes an unwinding mechanism, a guiding assembly, a fixing mechanism, a glue pulling mechanism, and a glue preparation mechanism. The unwinding mechanism is used to provide tape; the guiding assembly is used to guide the tape conveyed by the unwinding mechanism, the guiding assembly includes at least one guide roller for conveying the tape, at least one of the guide rollers being a movable guide roller; the fixing mechanism is used to clamp the conveyed tape, the fixing mechanism including a first fixing finger and a second fixing finger, the first fixing finger being located upstream of the movable guide roller and the second fixing finger being located downstream of the movable guide roller; the tape pulling mechanism is located downstream of the second fixing finger, used to move closer to the second fixing finger in a first direction or pull the conveyed tape in a second direction; and the tape preparation mechanism is drivenly connected to the movable guide roller, used to move the movable guide roller a preset distance in a third direction to complete tape buffering when the first fixing finger releases the tape and the second fixing finger clamps the tape; and to move the movable guide roller a preset distance in a fourth direction to complete tape conveying when the second fixing finger releases the tape and the first fixing finger clamps the tape; the first direction is opposite to the second direction, and the third direction is opposite to the fourth direction.

[0004] The adhesive feeding device provided in this application embodiment prepares adhesive by driving a movable guide roller along a third direction before applying the adhesive. During application, the adhesive-pulling finger pulls the adhesive tape along a second direction between the workpiece on the rotating fixture and the adhesive-applying device. The adhesive-applying device presses the adhesive tape onto the workpiece. The rotating fixture drives the workpiece to rotate, causing the adhesive tape to wrap around the workpiece. The movable guide roller moves along a fourth direction in coordination with the workpiece's rotation speed to deliver the adhesive. Before the next application, the movable guide roller moves again along a third direction to prepare adhesive.

[0005] In some embodiments, the adhesive preparation mechanism includes a first movable seat, a first guide member, and a first drive member. The movable guide roller is disposed on the first movable seat; the first movable seat is movably connected to the first guide member; and the first drive member is used to enable the first movable seat to move on the first guide member, thereby driving the movable guide roller to move along the third or fourth direction.

[0006] In this embodiment, the first moving seat is driven by the first driving member to move the movable guide roller along the first guide member in order to prepare or deliver glue.

[0007] In some embodiments, the first movable seat is a first slider, the first guide is a first slide rail, the first driving member is a first driving cylinder, the first slider is slidably engaged with the first slide rail, and the first driving cylinder is drivingly connected to the first slider.

[0008] In this way, the first slider and the first slide rail slide together, and the movable guide roller is fixed to the first slider, so that the movable guide roller can follow the first slider and move along the first slide rail to realize glue preparation or glue delivery.

[0009] In some embodiments, the first movable seat is a second slider with a first rack, the first guide is a second slide rail, the first drive member is a first drive motor with a first gear, the second slider slides in sliding engagement with the second slide rail, and the first drive motor and the second slider are connected to the first rack through the first gear meshing.

[0010] Thus, the second slider has a first rack, and the movable guide roller is fixed to the second slider. Through the meshing of the first rack and the second slide rail, the movable guide roller can follow the second slider and move along the second slide rail to realize glue preparation or glue delivery.

[0011] In some embodiments, the glue preparation mechanism further includes a first lead screw, the first movable seat is a third slider, the first guide is a third slide rail, the first driving member is a second driving motor, the third slider is threadedly connected to the first lead screw, and the second driving motor is drivenly connected to the first lead screw to drive the third slider to slide on the third slide rail.

[0012] Thus, the third slider is threadedly connected to the first lead screw, converting the rotational motion of the first lead screw into the linear motion of the third slider, so as to realize the preparation or delivery of glue.

[0013] In some embodiments, the first movable seat is a first gear seat with a second gear, the first guide is a second rack, the first driving member is a second driving cylinder, the first gear seat is meshed with the second rack, and the second driving cylinder is driven by the first gear seat.

[0014] Thus, the first gear seat has a second rack, and the movable guide roller is fixed to the first gear seat. Through the meshing of the second rack and the second gear, the movable guide roller can follow the first gear seat along the second rack to realize the preparation or delivery of glue.

[0015] In some embodiments, the guiding assembly includes at least two guide rollers for conveying the tape, at least one of the guide rollers being a fixed guide roller that is fixedly mounted.

[0016] The conveyor belt can be guided by fixed guide rollers and movable guide rollers, and the path of the conveyor belt can be formed by setting the positions of the fixed guide rollers and movable guide rollers.

[0017] In some embodiments, there are three fixed guide rollers, namely a first guide roller, a second guide roller, and a third guide roller. The first guide roller is located between the unwinding mechanism and the first fixed finger, the second guide roller is located downstream of the movable guide roller, and the third guide roller is located between the second guide roller and the second fixed finger, so that the tape forms a circuitous route around the first guide roller, the movable guide roller, the second guide roller, and the third guide roller.

[0018] In this way, the tape forms a circuitous route around the first guide roller, the movable guide roller, the second guide roller, and the third guide roller, which can reduce the space occupied by the tape and provide buffer space for intermittent tape feeding.

[0019] In some embodiments, the guide roller includes a guide shaft and an adjusting wheel. The guide shaft passes through the adjusting wheel, and the tape is wound around the adjusting wheel. The adjusting wheel is axially movable along the guide shaft to adjust the height position of the tape on the guide shaft.

[0020] Thus, taking the workpiece as an example, by controlling the height of the adjusting wheel, the height of the tape can be controlled, thereby controlling the height and position of the tape wrapping on the cell housing, so as to control the accuracy of the unpainted blank area between the top cover and the housing.

[0021] In some embodiments, the adhesive-pulling mechanism includes an adhesive-pulling finger, a second movable seat, a second guide member, and a second driving member. The adhesive-pulling finger is used to clamp the adhesive tape; the adhesive-pulling finger is disposed on the second movable seat; the second movable seat is movably connected to the second guide member; and the second driving member is used to enable the second movable seat to move on the second guide member, thereby driving the adhesive-pulling finger to move along the first direction or the second direction.

[0022] The second driving component can drive the rubber-pulling fingers on the second moving seat to move in the first direction or in the second direction.

[0023] In some embodiments, the second movable seat is a fourth slider, the second guide is a fourth slide rail, the second driving member is a third driving cylinder, the fourth slider is slidably engaged with the fourth slide rail, and the third driving cylinder is drivingly connected to the fourth slider.

[0024] In this way, the fourth slider and the fourth slide rail slide together, and the movable guide roller is fixed to the fourth slider, which allows the rubber-pulling finger to follow the fourth slider along the fourth slide rail.

[0025] In some embodiments, the second movable seat is a fifth slider with a third rack, the second guide is a fifth slide rail, the second drive member is a third drive motor with a third gear, the fifth slider is slidably engaged with the fifth slide rail, and the third drive motor is connected to the fifth slider through the third gear meshing with the third rack.

[0026] Thus, the fifth slider has a third rack, and the movable guide roller is fixed to the fifth slider. Through the meshing of the third rack and the third gear, the rubber-pulling finger can follow the fifth slider and move along the fifth slide rail.

[0027] In some embodiments, the glue preparation mechanism further includes a second lead screw, the second movable seat is a sixth slider, the second guide is a sixth slide rail, the second driving member is a fourth driving motor, the sixth slider is threadedly connected to the second lead screw, and the fourth driving motor is drivenly connected to the second lead screw to drive the sixth slider to slide on the sixth slide rail.

[0028] Thus, the sixth slider is threadedly connected to the second lead screw, converting the rotational motion of the second lead screw into the linear motion of the sixth slider. The sixth slider can then drive the rubber-pulling finger to move along the sixth slide rail.

[0029] In some embodiments, the second movable seat is a second gear seat with a fourth gear, the second guide is a fourth rack, the second driving member is a fourth driving cylinder, the second gear seat is meshed with the fourth rack, and the fourth driving cylinder is driven by the second gear seat.

[0030] Thus, the second gear seat has a fourth rack, and the movable guide roller is fixed to the second gear seat. Through the meshing of the fourth rack and the fourth gear, the rubber-pulling finger can follow the second gear seat to move along the fourth rack.

[0031] In some embodiments, the adhesive feeding device further includes an identification component for identifying the usage status of the adhesive tape.

[0032] By identifying the tape usage status through the identification component, the amount of tape used can be determined, thereby controlling the length of tape used for wrapping each workpiece and enabling timely replacement when the tape is about to run out.

[0033] In some embodiments, the identification component includes a counter disposed on the adhesive preparation mechanism for counting the number of movements of the movable guide roller to calculate the length of the adhesive tape used.

[0034] A counter can be used to easily control the length of tape movement, for example, to control the amount of tape used for wrapping a workpiece, or to ensure that the amount of tape used for wrapping a batch of workpieces is the same each time.

[0035] In some embodiments, the identification component includes an optical fiber sensor, which is configured corresponding to the unwinding mechanism to monitor the usage status of the tape on the unwinding mechanism.

[0036] Fiber optic sensors can monitor the usage status of the tape in real time, allowing for timely replacement.

[0037] In some embodiments, the identification component includes a counter disposed on the adhesive preparation mechanism for counting the number of movements of the movable guide roller to calculate the length of the adhesive tape used. The identification component also includes a fiber optic sensor disposed corresponding to the unwinding mechanism for monitoring the usage status of the adhesive tape on the unwinding mechanism.

[0038] A second aspect of this application aims to provide a coating apparatus, including a conveying device, a rotating device, a glue feeding device as described in any one of the preceding embodiments, a glue applying device, and a cutting device. The conveying device is used to convey a workpiece; the rotating device is used to place the workpiece conveyed by the conveying device and to enable the workpiece to rotate; the glue feeding device is used to provide adhesive tape for coating to the workpiece on the rotating device; the glue applying device is used to press the adhesive tape provided by the glue feeding device onto the workpiece, and to perform coating by driving the workpiece to rotate through the rotating device; and the cutting device is used to cut the adhesive tape provided by the glue feeding device to the workpiece.

[0039] The coating equipment of this application embodiment can automatically coat workpieces using a conveying device, a rotating device, a glue feeding device, a glue applying device, and a shearing device. It boasts a high degree of automation, replacing manual coating and improving coating quality and efficiency. Furthermore, the position of the glue applying device and the position and angle of the shearing can be controlled as needed to reduce the adverse effects of poor adhesion between the tape and the workpiece after coating.

[0040] In some embodiments, the adhesive applicator includes a first pressing assembly and a first driving assembly. The first pressing assembly is used to press the adhesive tape onto the workpiece; and the first driving assembly is drivenly connected to the first pressing assembly to enable the first pressing assembly to move.

[0041] In this embodiment, the first driving component drives the first pressing component to press the tape onto the workpiece to achieve adhesive coating.

[0042] In some embodiments, the first driving assembly includes a sliding seat and a third driving member. The first clamping assembly is slidably disposed on the sliding seat; the third driving member is drivenly connected to the first clamping assembly so that the first clamping assembly can move on the sliding seat along a fifth direction or a sixth direction; wherein the fifth direction is opposite to the sixth direction and is perpendicular to the first direction.

[0043] Thus, the third driving component causes the first pressing assembly to press the tape onto the workpiece.

[0044] In some embodiments, the first driving component includes a fourth driving member, which is drivenly connected to the slide block so that the slide block can drive the first pressing component to move along the first direction or the second direction.

[0045] This improves the adhesion between the tape pressed onto the workpiece surface and the workpiece, and increases the adhesion length.

[0046] In some embodiments, the overcoating equipment further includes a pressing device for pressing the tape onto the workpiece during the overcoating process driven by the rotating device.

[0047] By using a pressing device to press the tape on a localized area of ​​the workpiece during the coating process, the coating effect is improved.

[0048] In some embodiments, the clamping device includes a second clamping assembly and a second driving assembly. The second clamping assembly is used to clamp the tape onto the workpiece during the overmolding process; and the second driving assembly is drivenly connected to the second clamping assembly, enabling the second clamping assembly to rotate to accommodate the rotational position of the workpiece.

[0049] In this embodiment, since the distance between the outer contour of the workpiece and the second abutment changes during the workpiece's rotation, the second pressing component can be driven to rotate by the second driving component, so that the second abutment can press the tape onto the workpiece, thereby improving the adhesion between the tape and the workpiece and improving the coating quality.

[0050] In some embodiments, the coating equipment further includes a worktable, on which the conveying device, the rotating device, the adhesive feeding device, the adhesive applicator, and the cutting device are all disposed.

[0051] This allows for the rational arrangement of the positions of each mechanism according to the requirements of the coating process on the workpiece, resulting in a smaller space occupied by the coating equipment.

[0052] A third aspect of this application provides a coating system, including the coating equipment described in any of the preceding claims and a conveying channel. The conveying channel is used to convey workpieces and is disposed close to the coating equipment, so that the handling device can handle workpieces from the conveying channel to the rotating device or from the rotating device to the conveying channel.

[0053] In this embodiment, the conveying channel can transport the workpiece to be coated to a position where the handling device can clamp the workpiece, and can also transport the coated workpiece to the next process.

[0054] In some embodiments, the conveying channel includes a loading station and a buffer station. The loading station is used for loading workpieces; and the buffer station is used for buffering workpieces conveyed at the loading station, wherein the conveying device moves the workpieces from the buffer station to the rotating device or from the rotating device to the buffer station.

[0055] In this embodiment, the buffer can buffer multiple workpieces to be coated, enabling the conveying device to continuously move the workpieces, thereby improving the coating efficiency. Attached Figure Description

[0119] In related technologies, the battery cell includes a top cover and a housing, with the housing having an open end that connects to the top cover. Before painting the housing, the top cover needs to be placed over the open end of the housing, and the interface between the top cover and the housing is wrapped with adhesive to prevent painting at the interface during housing painting, which could affect the subsequent welding of the top cover and housing. After the housing is painted, the adhesive tape is removed, and then the top cover and housing are welded at the interface. In related technologies, the adhesive tape is applied to the housing manually. Manual operation can cause large fluctuations in the starting position of the adhesive application, resulting in incomplete wrapping, leaving gaps and bumps. Furthermore, the manual workload is high, production efficiency is low, and there are many rework items.

[0120] Based on this, please refer to Figures 1-4 This application provides a coating equipment 100 to replace manual labor in the coating process, thereby improving production efficiency and reducing the defect rate. It is understood that the coating equipment 100 in this application can be used for coating workpieces D such as battery cells, battery modules, or batteries, and can also be used for coating other workpieces D.

[0121] Please refer to Figures 1-4 The coating equipment 100 includes a conveying device 10, a rotating device 20, a glue feeding device 30, a glue applying device 40, and a shearing device 50. The conveying device 10 is used to convey the workpiece D; the rotating device 20 is used to place the workpiece D conveyed by the conveying device 10 and to enable the workpiece D to rotate; the glue feeding device 30 is used to provide the adhesive tape C required for coating to the workpiece D on the rotating device 20; the glue applying device 40 is used to press the adhesive tape C provided by the glue feeding device 30 onto the workpiece D, and the workpiece D is driven to rotate by the rotating device 20 to perform coating; the shearing device 50 is used to cut the adhesive tape C provided by the glue feeding device 30 to the workpiece D.

[0122] The conveying device 10 is used to move workpiece D, specifically by moving workpiece D from the conveyor channel 200 to the rotary device 20, or by moving workpiece D from the rotary device 20 to the conveyor channel 200 for the next process. For example, the conveying device 10 can be mounted on a fixed device such as a frame 11 using a servo mechanism, which drives workpiece D to move laterally (X) or vertically (Z). The conveying device 10 can also be equipped with a multi-joint robot, whose movement drives workpiece D to move.

[0123] The rotating device 20 is used to place the workpiece D and can at least change the position of the workpiece D. The position of the workpiece D refers to its ability to rotate to different orientations from the same location. After the conveying device 10 transports the workpiece D to the rotating device 20, the rotating device 20 can cause the workpiece D to rotate for the coating operation. It is understood that the rotating device 20 may be equipped with one or more rotating fixtures 22 for placing the workpiece D, and each rotating fixture 22 can be moved to the coating station E. When there is one rotating fixture 22, the rotating fixture 22 is located at the coating station E, and the conveying device 10 can directly transport the workpiece D to the coating station E, where the rotating fixture 22 causes the workpiece D to rotate at the coating station E for the coating operation. When there are two or more rotary fixtures 22, the rotary fixtures 22 can be located at the coating station E and the waiting station F. The waiting station F can be one or more. The rotary device 20 can also change the position of the workpiece D. The rotary fixtures 22 can move between the coating station E and the waiting station F. The workpiece D can follow the rotary fixtures 22 to switch between multiple positions and switch to the coating station E in sequence to perform the coating operation.

[0124] Understandably, while one workpiece D is being coated at the coating station E, the transport device 10 can pre-transfer another workpiece D to the waiting station F, thus improving work efficiency. For example, when two rotary clamps 22 are provided, they are positioned close to the transport device 10 and the adhesive applicator 40, respectively. One rotary clamp 22 is located at the waiting station F to receive the workpiece D transported by the transport device 10, while the other rotary clamp 22 is located at the coating station E to coat the workpiece D. After coating, the two rotary clamps 22 switch positions. In this way, workpieces D to be coated can be continuously provided to the coating station E, and coated workpieces D can be continuously switched to the waiting station F. The rotary clamp 22 can sequentially receive workpieces D transported by the transport device 10 at the waiting station F, and sequentially coat them at the coating station E by rotating.

[0125] It is understandable that "workpiece D to be coated" refers to workpiece D that has not yet been coated, and "workpiece D already coated" refers to workpiece D that has completed the coating process. The coating station E refers to the position where workpiece D is coated, close to the adhesive applicator 40. The waiting station F refers to the position where the conveying device 10 transports the workpiece D to the rotating device 20 to receive it. After coating, the coated workpiece D is moved to the waiting station F, and the conveying device 10 can also remove the coated workpiece D.

[0126] The adhesive feeding device 30 is used to supply adhesive tape C to the workpiece D to be coated at the coating station E. The adhesive feeding device 30 can intermittently release adhesive by controlling the movement stroke of the adhesive tape C. The adhesive feeding device 30 controls the tension of the adhesive tape C by fixing and moving it. It can be understood that before cutting the adhesive tape C, the adhesive feeding device 30 clamps the adhesive tape C to fix it; before coating the next workpiece D, the adhesive feeding device 30 moves the adhesive tape C between the workpiece D at the coating station E and the adhesive applicator 40.

[0127] The adhesive applicator 40 is used to press the adhesive tape C onto the workpiece D located at the coating station E. After the adhesive feeding device 30 conveys the adhesive tape C to the coating station E, the adhesive applicator 40 presses the adhesive tape C onto the workpiece D. It can be understood that before the adhesive applicator 40 presses the adhesive tape C, the workpiece D on the rotating device 20 is already located at the coating station E. The adhesive feeding device 30 moves the adhesive tape C between the workpiece D and the adhesive applicator 40, and the adhesive applicator 40 presses the adhesive tape C onto the workpiece D. The workpiece D, through the rotation of the rotating clamp 22, causes the adhesive tape C to wrap around the circumference of the workpiece D, thus achieving coating.

[0128] The shearing device 50 is used to cut the tape C. After the workpiece D at the coating station E is coated, the shearing device 50 cuts the tape C to separate the tape on the workpiece D from the tape on the glue feeding device. The shearing device 50 can also adjust the position and angle of the cut tape C as needed during the cutting process.

[0129] The coating equipment 100 of this application embodiment can automatically coat workpiece D with adhesive through a conveying device 10, a rotating device 20, an adhesive feeding device 30, an adhesive application device 40, and a shearing device 50. It has a high degree of automation, replacing manual coating and improving coating quality and efficiency. Furthermore, the position of the adhesive application and the position and angle of the shearing can be controlled as needed to reduce the adverse effects caused by poor adhesion between the adhesive tape C and the workpiece D after coating.

[0130] In some embodiments, please refer to Figures 5-8 The conveying device 10 includes a frame 11, a clamping mechanism 12, a transverse movement mechanism 13, and a vertical movement mechanism 14. The clamping mechanism 12 includes two sets of gripper assemblies 121, each of which can independently clamp the workpiece D. The transverse movement mechanism 13 is mounted on the frame 11 and is used to drive the clamping mechanism 12 to move laterally (X) along the frame 11. The vertical movement mechanism 14 is mounted on the transverse movement mechanism 13, and the clamping mechanism 12 is mounted on the vertical movement mechanism 14. The vertical movement mechanism 14 is used to drive the clamping mechanism 12 to move vertically (Z) along the frame 11.

[0131] The frame 11 serves as the mounting base for the clamping mechanism 12, the horizontal moving mechanism 13, and the vertical moving mechanism 14, and is used for the installation and positioning of these components. The clamping mechanism 12, the horizontal moving mechanism 13, and the vertical moving mechanism 14 are all directly or indirectly mounted on the frame 11. The frame 11 can provide mounting angles according to handling requirements. For example, according to the movement requirements of the horizontal moving mechanism 13, a horizontal support 111 is provided along the path that the horizontal moving mechanism 13 needs to move, so that the horizontal moving mechanism 13 can move along the horizontal support 111 to handle workpiece D. According to the movement requirements of the vertical moving mechanism 14, a vertical support 112 is provided along the path that the vertical moving mechanism 14 needs to move, so that the vertical moving mechanism 14 can move along the vertical support 112 to handle workpiece D.

[0132] The clamping mechanism 12 is used to clamp or release workpiece D. The clamping mechanism 12 includes two sets of gripper assemblies 121, each set of gripper assemblies 121 including clamping members capable of moving in opposite directions. For example, the gripper assembly 121 can clamp workpiece D, moving it with the conveying device 10 to or from the rotating device 20. The clamping members are arranged in pairs, and the number of pairs is unlimited. For example, each set of gripper assemblies 121 can be configured with one or two sets of clamping members; when there are two sets of clamping members, workpiece D can be clamped in two directions respectively.

[0133] The transverse mechanism 13 provides power for the transverse movement of the vertical mechanism 14 and the clamping mechanism 12, enabling the clamping mechanism 12 to move laterally along the X-axis of the frame 11 after clamping the workpiece D. For example, the transverse mechanism 13 can move the vertical mechanism 14 above the rotating device 20, and the clamping mechanism 12 and the workpiece D follow the vertical mechanism 14. Exemplarily, the transverse mechanism 13 includes a transverse slider 132 and a transverse slide rail 131, the transverse slide rail 131 being arranged laterally along the frame 11, the transverse slider 132 and the transverse slide rail 131 being slidably connected, and the vertical mechanism 14 and the clamping mechanism 12 being fixed to the transverse slider 132. Through the slidable connection between the transverse slider 132 and the transverse slide rail 131, the transverse mechanism 13 can move laterally on the frame 11. Exemplarily, the transverse mechanism 13 also includes a transverse drive member 133, which is drivenly connected to the transverse slider 132 for driving the transverse slider 132 to move laterally along the X-axis of the frame 11.

[0134] The vertical movement mechanism 14 provides the power for the vertical movement of the clamping mechanism 12, enabling the clamping mechanism 12 to move vertically along the Z-axis of the frame 11 after clamping the workpiece D. For example, after the horizontal movement mechanism 13 moves the workpiece D above the rotating device 20, the vertical movement mechanism 14 can lower the workpiece D onto the rotating device 20. Exemplarily, the vertical movement mechanism 14 includes a vertical movement slider 142 and a vertical movement rail 141. The vertical movement rail 141 is vertically disposed on the horizontal movement slider 132 along the frame 11. The vertical movement slider 142 and the vertical movement rail 141 are slidably connected, and the clamping mechanism 12 is fixed to the vertical movement slider 142. Through the slidable connection between the vertical movement slider 142 and the vertical movement rail 141, the clamping mechanism 12 can move vertically along the Z-axis on the frame 11. Exemplarily, the vertical movement mechanism 14 also includes a vertical movement drive 143, which is drivenly connected to the vertical movement slider 142 for driving the clamping mechanism 12 to move vertically along the Z-axis of the frame 11.

[0135] In this embodiment, through the cooperation of the various components in the conveying device 10, the workpiece D can be moved along the horizontal X or vertical Z direction on the conveying device 10, so that the workpiece D can reach the rotating device 20 or be removed from the rotating device 20 for the next process.

[0136] In some embodiments, please refer to Figure 5 The gripping mechanism 12 also includes two first rotation drive members 122, which are disposed on the vertical movement mechanism 14. Each first rotation drive member 122 is connected to a set of gripper assemblies 121 and is used to drive the corresponding gripper assembly 121 to rotate.

[0137] The first rotary drive 122 provides power to rotate the gripper assembly 121, enabling the gripper assembly 121 to rotate by a preset angle and change its orientation. When the gripper assembly 121 holds a workpiece D, it can change the orientation of the workpiece D. For example, when the workpiece D is a square battery cell, the first rotary drive 122 can drive the square battery cell to rotate by a preset angle, such as 90°, 180°, or 270°, etc.

[0138] It is understood that each first rotary drive 122 is connected to a set of gripper assemblies 121, each gripper assembly 121 can rotate independently, and the rotation angles of the two sets of gripper assemblies 121 can be the same or different.

[0139] In this embodiment, the orientation of the gripper assembly 121 can be changed by the first rotary drive member 122, so that the gripper assembly 121 can smoothly grip the workpiece D, or the orientation of the gripper assembly 121 can be changed to change the orientation of the workpiece D, so that the workpiece D can be smoothly placed in a preset position, such as on the rotating device 20. For example, see Figure 1The conveying channel 200 is arranged along the longitudinal direction Y. When the workpiece D is a square battery cell, the large surface of the battery cell, i.e. the length direction of the battery cell, is parallel to the longitudinal direction Y and is conveyed on the conveying channel 200. The large surface of the battery cell located at the waiting station F on the rotating device 20 is parallel to the transverse direction X. The battery cell at the waiting station F is perpendicular to the placement orientation of the battery cell on the conveying channel 200. Therefore, the position of the battery cell can be changed by the first rotating drive 122 to adapt to the change of the placement orientation of the battery cell.

[0140] For example, the conveying device 10 also includes an eighth driving member disposed on the vertical moving mechanism 14. The eighth driving member is drivenly connected to the two sets of gripper assemblies 121 and is used to drive the two sets of gripper assemblies 121 to rotate to switch positions.

[0141] In this embodiment, the eighth driving component drives the two sets of gripper assemblies 121 to switch positions. When there are two parallel conveyor channels 200, the workpiece D to be coated is first placed on the waiting station F, and then the same gripper assembly 121 is used to grip the workpiece D to be coated. By switching the positions of the two sets of gripper assemblies 121, when the gripper assembly 121 holding the coated workpiece D is aligned with one conveyor channel 200, the other set of gripper assemblies 121 holding the workpiece D to be coated can be aligned with the other conveyor channel 200 at the same time.

[0142] In some embodiments, please refer to Figures 9-12 The rotating device 20 includes a rotating table 21, two rotating clamps 22, a second rotating drive 23, and a third rotating drive 24. The two rotating clamps 22 are located on the rotating table 21 and are used to carry workpieces D. The second rotating drive 23 is connected to the rotating clamps 22 and is used to drive the rotating clamps 22 to rotate so that the workpiece D on the rotating clamps 22 can rotate. The third rotating drive 24 is connected to the rotating table 21 and is used to drive the rotating table 21 to rotate so as to change the position of the two rotating clamps 22.

[0143] The rotary table 21 supports the rotary fixture 22, and the second rotary drive 23 drives the rotary fixture 22 to rotate, thereby changing the position of the workpiece D on the rotary fixture 22. For example, two rotary fixtures 22 are arranged opposite to each other on the rotary table 21, close to the conveying device 10 and the adhesive applicator 40 respectively, and can stay at the waiting station F or the adhesive application station E. The conveying device 10 transports the workpiece D to the rotary fixture 22 located at the waiting station F, and the rotary fixture 22 follows the rotary table 21 to the adhesive application station E, so as to be close to the adhesive applicator 40 for adhesive application.

[0144] Understandably, while one rotary fixture 22 is positioned at waiting station F on the rotary table 21, awaiting placement of workpiece D by the transport device 10, another rotary fixture 22 is performing adhesive application at the adhesive application station E. In this way, the adhesive application device 40 can continuously apply adhesive to workpiece D. During adhesive application, the transport device 10 prepares the next workpiece D, allowing the adhesive application process to continue uninterrupted. This reduces the time required for the next workpiece D to be moved closer to the adhesive application device 40 after one workpiece D has been applied, thus improving adhesive application efficiency.

[0145] The rotary clamp 22 is used to clamp the workpiece D, and the conveying device 10 transports the workpiece D onto the rotary clamp 22. The rotary clamp 22 is provided with limiting members that can move in opposite directions to limit the displacement of the workpiece D, so as to stably clamp the workpiece D. The limiting members are arranged in pairs, and the number of pairs is unlimited. For example, the limiting members can be set as one set or two sets. When there are two sets of limiting members, the workpiece D can be clamped in two directions. When the workpiece D is a square-shell battery cell, the limiting members can clamp the square-shell battery cell in two directions. When the square-shell battery cell includes length and width, more limiting members can be set on the larger surface of the battery cell in the length direction to improve the limiting effect. For example, two sets of limiting members can be set in the length direction to improve the limiting effect. After the adhesive applicator 40 presses the adhesive tape C onto the workpiece D, the rotary clamp 22 can rotate under the drive of the second rotary drive member 23 to achieve adhesive wrapping.

[0146] Understandably, since the conveying device 10 has two sets of gripper assemblies 121, after one set of gripper assemblies 121 grips the already coated workpiece D, the other set of gripper assemblies 121 places the workpiece D to be coated onto the rotary fixture 22. After the workpiece D on the other rotary fixture 22 has been coated, the positions are switched again. When gripper assemblies 121 grip the workpiece D on the rotary fixture 22, they can be rotated to a direction corresponding to the workpiece D on the rotary fixture 22, or the rotary fixture 22 can be rotated to a direction corresponding to the gripper assemblies 121.

[0147] The second rotary drive 23 provides power for the rotation of the rotary fixture 22, which can rotate to change its orientation. The orientation of the rotary fixture 22 refers to its ability to be positioned in different orientations from the same location through rotation. When a workpiece D is placed on the rotary fixture 22, the orientation of the workpiece D can be changed. During overmolding, power is provided to rotate the workpiece D to achieve overmolding. For example, a second rotary drive 23 can be provided at the overmolding station E to control the rotation of the rotary fixture 22 at the overmolding station E. Alternatively, second rotary drives 23 can be provided at both the overmolding station E and the waiting station F to drive two rotary fixtures 22 respectively. When a second rotary drive 23 is provided at the waiting station F near the conveying device 10, the gripping mechanism 12 may not need a first rotary drive 122; instead, the workpiece D can be rotated by the second rotary drive 23 at the waiting station F to adapt to the placement orientation of the workpiece D on the conveying channel 200. If the first rotary drive 122 is not provided, the clamping orientation of the gripper assembly 121 on the clamping mechanism 12 is adapted to the placement orientation of the workpiece D on the conveying channel 200.

[0148] The third rotary drive 24 provides power for the rotation of the rotary table 21. The rotary fixture 22 can rotate with the rotary table 21, changing its position and switching between the waiting station F and the coating station E. When a workpiece D is placed on the rotary fixture 22, its position can be changed. Before coating, the workpiece D to be coated can be moved to a position closer to the adhesive applicator 40; after coating, the coated workpiece D can be moved to another position.

[0149] It is understandable that both the second rotary drive member 23 and the third rotary drive member 24 can be located on the opposite side of the rotary table 21 relative to the rotary clamp 22. For example, the rotary clamp 22 is above the rotary table 21, and the second rotary drive member 23 and the third rotary drive member 24 are below the rotary table 21. This is to avoid the second rotary drive member 23 and the third rotary drive member 24 occupying the usable space above the rotary table 21, thus simplifying the layout above the rotary table 21. The drive connection between the second rotary drive member 23 and the rotary clamp 22 is designed for easy connection to drive the rotary clamp 22 to rotate. When the third rotary drive member 24 drives the rotary table 21 to rotate, the second rotary drive member 23 can be separated from the rotary clamp 22.

[0150] In this embodiment, through the cooperation of the rotary table 21, the rotary fixture 22, the second rotary drive 23, and the third rotary drive 24, the positions of the coated workpiece D and the workpiece D to be coated can be switched after the coating of a workpiece D is completed. The workpiece D to be coated is switched to the coating station E, and the coated workpiece D is switched to the waiting station F, which enables continuous coating, reduces waiting time, and improves coating efficiency.

[0151] In some embodiments, please refer to Figure 9 The rotating device 20 also includes a pressing mechanism 25 for pressing the workpiece D on one of the rotating clamps 22, so that after the adhesive applicator 40 presses the adhesive tape C provided by the adhesive feeding device 30 onto the workpiece D, the workpiece D can rotate under the pressing of the pressing mechanism 25 to be coated with adhesive.

[0152] The pressing mechanism 25 provides pressure to press the workpiece D. When the workpiece D rotates for coating, the pressing mechanism 25 presses down on it to improve its stability and reduce the negative impact of the workpiece D swaying on the rotating device 20 on the coating quality. It is understood that the pressure of the pressing mechanism 25 is sufficient to meet the stability requirements of the workpiece D without affecting its rotation for coating.

[0153] For example, when workpiece D is a battery cell, the top cover of the battery cell is placed on the open end above the housing. At this time, the top cover and the housing are not yet welded. The pressing mechanism 25 can make the connection between the top cover and the housing more secure, so as to prevent the top cover from detaching from the housing or changing its position on the housing during the encapsulation process.

[0154] In some embodiments, please refer to Figure 9 The pressing mechanism 25 includes a support frame 251, a pressing member 252, and a pressing drive member 253. The pressing drive member 253 is disposed on the support frame 251, and the pressing member 252 is rotatably connected to the pressing drive member 253. The pressing drive member 253 is used to drive the pressing member 252 to descend or rise, so as to abut or release the workpiece D on the rotating clamp 22.

[0155] The support frame 251 serves as the mounting base for the components in the pressing mechanism 25, and is used for the installation and positioning of the pressing member 252 and the pressing drive member 253. The support frame 251 is located above the overmolding station E. The specific structure of the support frame 251 is not limited, as long as it enables the pressing member 252 to be positioned above the workpiece D and apply pressure to the workpiece D. For example, the support frame 251 includes a horizontal support bar 2511 and a vertical support bar 2512. The pressing member 252 and the pressing drive member 253 are located on the horizontal support bar 2511, and the vertical support bar 2512 can adjust the height of the horizontal support bar 2511.

[0156] The pressing member 252 is used to abut or move away from the workpiece D to apply or release pressure to the workpiece D. The pressing member 252 can rotate with the workpiece D.

[0157] The pressure drive 253 provides power for the pressure member 252 to move toward the workpiece D, enabling the pressure drive 253 to descend and abut against the workpiece D on the rotating fixture 22. After the coating is completed, the pressure drive 253 can drive the pressure member 252 to rise and move away from the workpiece D to relieve the pressure on the workpiece D.

[0158] The pressing drive component 253 is located on the support frame 251. Exemplarily, the support frame 251 includes a fixing plate 2513, which is arranged in the direction of movement of the pressing component 252, and the pressing drive component 253 is disposed on the fixing plate 2513. Exemplarily, the support frame 251 includes a horizontal support bar 2511 and a vertical support bar 2512, and the fixing plate 2513 is fixed to the horizontal support bar 2511.

[0159] In this embodiment, the pressing drive 253 drives the pressing member 252 to move closer to or further away from the workpiece D, so that the workpiece D on the rotating fixture 22 can rotate stably during the self-rotation and adhesive application, reducing the possibility of workpiece D shaking and affecting the adhesive application quality. After adhesive application, the pressing member 252 releases its pressure on the workpiece D, allowing the adhesive-coated workpiece D to rotate with the rotating table 21.

[0160] In some embodiments, Figures 13-22 The adhesive feeding device 30 includes an unwinding mechanism 31, a guiding assembly 32, a fixing mechanism 33, an adhesive pulling mechanism 34, and an adhesive preparation mechanism 35. The unwinding mechanism 31 provides adhesive tape C; the guiding assembly 32 guides the adhesive tape C fed by the unwinding mechanism 31, and includes at least one guide roller 321 for feeding the adhesive tape C, at least one of the guide rollers 321 being a movable guide roller 3212; the fixing mechanism 33 clamps the fed adhesive tape C, and includes a first fixing finger 331 and a second fixing finger 332, the first fixing finger 331 being located upstream of the movable guide roller 3212, and the second fixing finger 332 being located downstream of the movable guide roller 3212; the adhesive pulling mechanism 34 is located downstream of the second fixing finger 332 and is used to pull the adhesive tape along a first direction... The tape C is moved toward X1 closer to the second fixed finger 332 or pulled along the second direction X2; the tape preparation mechanism 35 is driven to connect with the movable guide roller 3212, and is used to move the movable guide roller 3212 a preset distance along the third direction Y1 to complete the buffering of the tape C when the first fixed finger 331 releases the tape C and the second fixed finger 332 clamps the tape C; when the second fixed finger 332 releases the tape C and the first fixed finger 331 clamps the tape C, the movable guide roller 3212 moves a preset distance along the fourth direction Y2 to complete the conveying of the tape C; the first direction X1 is opposite to the second direction X2, and the third direction Y1 is opposite to the fourth direction Y2.

[0161] It is understood that the embodiments of this application Figure 13 , Figure 14 , Figure 16 , Figures 18-21 , Figures 23-25 as well as Figure 30 In the middle, the first direction X1, the second direction X2, the third direction Y1, the fourth direction Y2, the fifth direction Y3, and the sixth direction Y4 are... Figure 1The XYZ coordinate system in the diagram does not necessarily have a relationship; the orientation shown is only one embodiment. Depending on the needs of the component layout, the orientation relationships between the first direction X1, the second direction X2, the third direction Y1, the fourth direction Y2, the fifth direction Y3, and the sixth direction Y4 and the XYZ coordinate system can be changed. Alternatively, the orientation relationships between the three sets of orientations—first direction X1 and second direction X2, third direction Y1 and fourth direction Y2, and fifth direction Y3 and sixth direction Y4—can also be changed.

[0162] An unwinding mechanism 31 is used to provide tape C and is positioned close to the guide assembly 32. Exemplarily, the unwinding mechanism 31 includes a tray 311 and a rotating shaft 312. The disc-shaped tape C with a rotating core is fitted onto the rotating shaft 312 and located on the tray 311. The tray 311 is rotatable relative to the rotating shaft 312 and can be adjusted to a suitable height to facilitate the connection of tape C to the guide assembly 32. It is understood that the tape C on the unwinding mechanism 31 can be pulled out under tension during tape preparation.

[0163] The guiding component 32 is used to guide the conveying of tape C, thereby changing the conveying direction of tape C and enabling tape C to be conveyed along a preset trajectory. This optimizes the component layout of the glue feeding device 30, making the positional relationship between the glue feeding device 30 and other process devices more reasonable. The guiding component 32 includes guide rollers 321, which adjust the conveying trajectory of tape C. Exemplarily, at least one of the guide rollers 321 is a movable guide roller 3212, for example, there may be one, two, or more movable guide rollers 3212. One movable guide roller 3212 can provide buffer tape for the coating of one workpiece D, or it can provide buffer tape for the coating of multiple workpieces D. Two or more movable guide rollers 3212 can jointly provide buffer tape for the coating of one workpiece D, or it can provide buffer tape for the coating of multiple workpieces D. The guide roller 321 can be further divided into a fixed guide roller 3211 and a movable guide roller 3212. The arrangement of the fixed guide roller 3211 and the movable guide roller 3212 forms a preset trajectory for the movement of the tape C. The position of the fixed guide roller 3211 remains unchanged, while the movable guide roller 3212 can drive the tape C to move, adjust the length of the tape C that has left the unwinding mechanism 31, and adjust the tension of the tape C.

[0164] The fixing mechanism 33 is used to fix the tape C, restricting the movement of the tape C by clamping a portion of the tape C. The fixing mechanism 33 includes a first fixing finger 331 and a second fixing finger 332. The first fixing finger 331 can clamp or release the tape C upstream of the movable guide roller 3212, and the second fixing finger 332 can clamp or release the tape C downstream of the movable guide roller 3212. When the first fixing finger 331 releases the tape C and the second fixing finger 332 clamps the tape C, the movable guide roller 3212 moves in the third direction Y1, and the unwinding mechanism 31 releases the tape C to buffer the tape C in preparation for conveying the tape C during the wrapping process. When the second fixing finger 332 releases the tape C and the first fixing finger 331 clamps the tape C, the tape pulling mechanism 34 or the workpiece D on the wrapping station E drives the tape C, causing the movable guide roller 3212 to move a preset distance along the fourth direction Y2, conveying the tape C to wrap the workpiece D on the wrapping station E.

[0165] The adhesive pulling mechanism 34 is used to move the tape C along the second direction X2, either by approaching or from the second fixed finger 332 in the first direction X1. During the coating process, the adhesive pulling mechanism 34 pulls the tape C between the workpiece D on the rotating clamp 22 located at the coating station E and the adhesive applicator 40, so that the adhesive applicator 40 can press the tape C onto the workpiece D.

[0166] The adhesive preparation mechanism 35 drives the movable guide roller 3212 to move along the third direction Y1 and the fourth direction Y2 to buffer the tape C before applying adhesive or to transport the tape C during application. The adhesive preparation mechanism 35 is driven to connect with the movable guide roller 3212 so that the movable guide roller 3212 moves the tape C. It can be understood that when the first fixing finger 331 clamps the tape C, the second fixing finger 332 releases the tape C, and the movable guide roller 3212 is fixed, the adhesive pulling mechanism 34 pulls the tape C along the first direction X1 or the second direction X2, which can adjust the tension of the tape C to a suitable tension for application. At the same time, it can reduce the adverse effects of poor adhesion between the tape C and the workpiece D caused by excessive slackness of the tape C, and reduce the adverse effects of excessive tightness of the tape C causing stretching deformation or breakage.

[0167] In this embodiment, before coating, the movable guide roller 3212 is moved along the third direction Y1 by the glue preparation mechanism 35 to prepare the glue. During coating, the glue-pulling finger 341 pulls the tape C along the second direction X2 to the middle between the workpiece D on the rotating clamp 22 and the adhesive applicator 40. The adhesive applicator 40 presses the tape C onto the workpiece D. The rotating clamp 22 drives the workpiece D to rotate, causing the tape C to wrap around the workpiece D. The movable guide roller 3212 moves along the fourth direction Y2 in coordination with the rotation speed of the workpiece D to deliver the glue. Before the next coating, the movable guide roller 3212 moves again along the third direction Y1 to prepare the glue.

[0168] For example, the first direction X1 and the second direction X2 group are perpendicular to the third direction Y1 and the fourth direction Y2 group.

[0169] For example, both the first fixed finger 331 and the second fixed finger 332 include a finger clip 33a, a finger drive member 33b, and a finger retainer 33c. See also Figure 15 Taking the second fixed finger 332 as an example, the finger drive 33b is driven to connect with the finger clip 33a. The finger holder 33c is used to mount the finger drive 33b and the finger clip 33a. The height of the finger clip 33a on the finger holder 33c can be adjusted according to the height of the tape C, or the height dimension of the finger clip 33a can be designed to accommodate changes in the height of the tape C, so as to clamp and fix the tape C. Exemplarily, the finger drive 33b is a cylinder, such as a finger cylinder.

[0170] Understandably, please refer to Figure 14 and Figure 15 The position of the finger drive 33b of the second fixed finger 332 is set so as not to affect the rotation of the workpiece D on the coating station E. For example, the finger drive 33b is arranged vertically to avoid interfering with the rotation of the workpiece D on the coating station E.

[0171] In some embodiments, please refer to Figures 23-26 The glue preparation mechanism 35 includes a first movable seat 351, a first guide member 352, and a first drive member 353. A movable guide roller 3212 is disposed on the first movable seat 351; the first movable seat 351 is movably connected to the first guide member 352; the first drive member 353 enables the first movable seat 351 to move on the first guide member 352, thereby driving the movable guide roller 3212 to move along a third direction Y1 or a fourth direction Y2.

[0172] The first movable seat 351 is used to install the movable guide roller 3212. The movable guide roller 3212 moves relative to the first guide member 352 on the first movable seat 351 so that the movable guide roller 3212 can drive the tape C to move, so as to realize the preparation or delivery of adhesive.

[0173] The first guide member 352 is used to guide the movement direction of the first movable seat 351, and the movable guide roller 3212 can move back and forth on the first guide member 352. The first guide member 352 is arranged along the third direction Y1 and the fourth direction Y2, and the movable guide roller 3212 can move along the third direction Y1 or along the fourth direction Y2 on the first guide member 352.

[0174] The first drive member 353 is used to provide power for the first movable seat 351 to move along the first guide member 352. The first drive member 353 can control the first movable seat 351 to move or stop moving.

[0175] It is understandable that the length of the movable guide roller 3212 moving in one direction on the first guide member 352 is sufficient to meet the amount of tape C used for one or more coatings.

[0176] In this embodiment, the first moving seat 351 is driven by the first driving member 353 to move the movable guide roller 3212 along the first guide member 352, so as to realize the preparation or delivery of glue.

[0177] The method by which the first movable seat 351 and the first guide member 352 are movably connected is not limited, as long as the movable guide roller 3212 on the first movable seat 351 can move along a preset trajectory. For example, the first movable seat 351 can be moved along the first guide member 352 by means of gear transmission, chain transmission, screw transmission or belt transmission.

[0178] In some embodiments, please refer to Figures 23-26 The first movable seat 351 is the first slider, the first guide 352 is the first slide rail, the first driving component 353 is the first driving cylinder, the first slider is slidably engaged with the first slide rail, and the first driving cylinder is drivingly connected to the first slider.

[0179] The first slider and the first slide rail cooperate to slide. The movable guide roller 3212 is fixed to the first slider, enabling the movable guide roller 3212 to follow the first slider along the first slide rail to achieve glue preparation or delivery. The first drive cylinder is used to drive the first slider to slide. For example, the first drive component 353 can be a drive cylinder, a drive hydraulic cylinder, or a drive electric cylinder to reduce production costs. The first drive component 353 can also be a finger cylinder to improve movement accuracy and stability.

[0180] In some embodiments not shown, the first movable seat 351 is a second slider with a first rack, the first guide 352 is a second slide rail, the first drive member 353 is a first drive motor with a first gear, the second slider slides in sliding engagement with the second slide rail, and the first drive motor and the second slider are connected by meshing with the first rack through the first gear.

[0181] The second slider has a first rack, and the movable guide roller 3212 is fixed to the second slider. Through the engagement of the first rack and the second slide rail, the movable guide roller 3212 can follow the second slider along the second slide rail to achieve glue preparation or delivery. This enhances the control precision of the moving distance of the movable guide roller 3212, thereby improving the control precision of the moving distance of the tape C. For example, during glue preparation and wrapping, the length of the tape C can be precisely controlled. Exemplarily, the first drive motor may include a servo motor to further improve the control precision of the moving distance of the tape C.

[0182] In some embodiments not shown, the glue preparation mechanism 35 further includes a first lead screw, a first movable seat 351 which is a third slider, a first guide 352 which is a third slide rail, a first drive member 353 which is a second drive motor, the third slider is threadedly connected to the first lead screw, and the second drive motor is drivenly connected to the first lead screw to drive the third slider to slide on the third slide rail.

[0183] The third slider is threadedly connected to the first lead screw, converting the rotational motion of the first lead screw into the linear motion of the third slider to achieve glue preparation or delivery. Thus, the third slider can drive the movable guide roller 3212 to move along the third slide rail to achieve glue preparation or delivery. For example, the second drive motor may include a servo motor to further improve the control accuracy of the tape C's movement distance.

[0184] In some embodiments not shown, the first movable seat 351 is a first gear seat with a second gear, the first guide 352 is a second rack, the first drive member 353 is a second drive cylinder, the first gear seat is meshed with the second rack, and the second drive cylinder is driven by the first gear seat.

[0185] The first gear seat has a second rack, and the movable guide roller 3212 is fixed to the first gear seat. Through the meshing of the second rack and the second gear, the movable guide roller 3212 can follow the first gear seat along the second rack to achieve glue preparation or delivery. This enhances the control precision of the movable guide roller 3212's movement distance, thereby improving the control precision of the tape C's movement distance. For example, during glue preparation and wrapping, the length of tape C can be precisely controlled. Exemplarily, the second drive cylinder can include a drive cylinder, a drive hydraulic cylinder, or a drive electric cylinder to reduce production costs. The second drive cylinder can also include a finger cylinder to improve movement accuracy and stability.

[0186] In some embodiments, the guiding assembly 32 includes at least two guide rollers 321 for conveying the tape C, at least one of the guide rollers 321 being a fixed guide roller 3211. In this embodiment, the tape can be guided by the fixed guide roller 3211 and the movable guide roller 3212, and the position of the fixed guide roller 3211 and the movable guide roller 3212 is set to form the path of the tape C. Exemplarily, the guiding assembly 32 includes one fixed guide roller 3211 and one movable guide roller 3212. Exemplarily, the guiding assembly 32 includes two movable guide rollers 3212 and one fixed guide roller 3211, both of the movable guide rollers 3212 being movable to realize adhesive preparation or adhesive delivery.

[0187] In some embodiments, please refer to Figure 20There are three fixed guide rollers 3211, namely the first guide roller 32111, the second guide roller 32112, and the third guide roller 32113. The first guide roller 32111 is located between the unwinding mechanism 31 and the first fixed finger 331. The second guide roller 32112 is located downstream of the movable guide roller 3212. The third guide roller 32113 is located between the second guide roller 32112 and the second fixed finger 332, so that the tape C forms a meandering route around the first guide roller 32111, the movable guide roller 3212, the second guide roller 32112, and the third guide roller 32113.

[0188] After tape C is output from unwinding mechanism 31, it passes sequentially through first guide roller 32111, movable guide roller 3212, second guide roller 32112, and third guide roller 32113 to reach tape pulling mechanism 34, where tape pulling mechanism 34 clamps tape C at its starting position. The tape C's circuitous route around first guide roller 32111, movable guide roller 3212, second guide roller 32112, and third guide roller 32113 reduces the space occupied by tape C, providing buffer space for intermittent tape feeding.

[0189] The layout of the unwinding mechanism 31, the first guide roller 32111, and the second guide roller 32112 can be reasonably arranged according to the layout of the overcoating equipment 100. For example, while meeting the requirements for the length of adhesive tape C, the unwinding mechanism 31 and the first fixed finger 331 can be located on both sides of the first guide roller 32111 along the third direction Y1 or the fourth direction Y2, respectively, so as to make the layout more compact.

[0190] It is understandable that the side of tape C that contacts guide roller 321 is the non-adhesive side.

[0191] In some embodiments, please refer to Figure 26 The guide roller 321 includes a guide shaft 3214 and an adjusting wheel 3215. The guide shaft 3214 passes through the adjusting wheel 3215, and the tape C is wound around the adjusting wheel 3215. The adjusting wheel 3215 can move axially along the guide shaft 3214 to adjust the height position of the tape C on the guide shaft 3214.

[0192] The guide shaft 3214 guides the movement of the adjusting wheel 3215. The adjusting wheel 3215 drives the tape C to move along the guide shaft 3214, thereby changing the height of the tape C. Thus, taking the workpiece D as an example of a battery cell, by controlling the height of the adjusting wheel 3215, the height of the tape C can be controlled, thereby controlling the height position of the tape C wrapped on the battery cell housing, and thus controlling the accuracy of the unpainted blank area between the top cover and the housing.

[0193] For example, the adjusting wheel 3215 includes two limiting wheels 3215a arranged along the guide shaft 3214 and a connecting ring 3215b. The connecting ring 3215b is located between the two limiting wheels 3215a and is fixedly connected to the two limiting wheels 3215a. The tape C is wound around the connecting ring 3215b. The height difference between the two limiting wheels 3215a is adapted to the width of the tape C to limit the vertical movement of the tape C.

[0194] For example, the friction between the side of tape C that contacts the adjusting wheel 3215 and the adjusting wheel 3215 is sufficient to prevent tape C from moving up and down.

[0195] In some embodiments, please refer to Figure 16 and Figure 17 The adhesive-pulling mechanism 34 includes an adhesive-pulling finger 341, a second movable seat 342, a second guide member 343, and a second driving member 344. The adhesive-pulling finger 341 is used to clamp the adhesive tape C; the adhesive-pulling finger 341 is disposed on the second movable seat 342; the second movable seat 342 is movably connected to the second guide member 343; the second driving member 344 is used to enable the second movable seat 342 to move on the second guide member 343, thereby driving the adhesive-pulling finger 341 to move along the first direction X1 or the second direction X2.

[0196] The adhesive finger 341 can grip or release the adhesive tape C.

[0197] The second movable seat 342 is used to install the adhesive-pulling finger 341 and the second drive member 344. The adhesive-pulling finger 341 moves relative to the second guide member 343 on the second movable seat 342 so that the adhesive-pulling finger 341 can drive the tape C to move.

[0198] The second guide member 343 is used to guide the movement direction of the second movable seat 342, and the adhesive-pull finger 341 can move back and forth on the second guide member 343. The second guide member 343 is arranged along the first direction X1 and the second direction X2, and the adhesive-pull finger 341 can move along the first direction X1 or along the second direction X2 on the second guide member 343.

[0199] The second drive member 344 is used to provide power for the second movable seat 342 to move along the second guide member 343, and the second drive member 344 can control the second movable seat 342 to move or stop moving.

[0200] Understandably, after the adhesive applicator 40 presses the adhesive tape C onto the workpiece D, the adhesive-pulling finger 341 releases the adhesive tape C to avoid affecting the workpiece D's rotation with the rotating fixture 22 for adhesive application. The adhesive-pulling finger 341 can move the adhesive tape C to a suitable position to reduce the adverse effects of excess adhesive tape C on the adhesive application.

[0201] The method by which the second driving component 344 drives the second movable seat 342 to move the adhesive-pulling finger 341 is not limited, as long as it enables the adhesive-pulling finger 341 to clamp the adhesive tape C and move along the first direction X1 or the second direction X2. For example, the adhesive-pulling finger 341 can be moved by gear transmission, chain transmission, screw transmission or belt transmission.

[0202] In some embodiments not shown, the second movable seat 342 is the fourth slider, the second guide 343 is the fourth slide rail, the second drive member 344 is the third drive cylinder, the fourth slider is slidably engaged with the fourth slide rail, and the third drive cylinder is drivenly connected to the fourth slider.

[0203] The fourth slider and the fourth slide rail slide together, and the movable guide roller 3212 is fixed to the fourth slider, enabling the adhesive-pulling finger 341 to follow the fourth slider along the fourth slide rail. The third drive cylinder is used to drive the fourth slider to slide. Exemplarily, the third drive component 422 can be a drive cylinder, a drive hydraulic cylinder, or a drive electric cylinder to reduce production costs. The third drive component 422 can also be a finger cylinder to improve movement accuracy and stability.

[0204] In some embodiments, see Figure 17 The second movable seat 342 is a fifth slider with a third rack 3421, the second guide 343 is a fifth slide rail, the second drive member 344 is a third drive motor with a third gear 3441, the fifth slider and the fifth slide rail are in sliding engagement, and the third drive motor and the fifth slider are connected by the third gear 3441 and the third rack 3421.

[0205] The fifth slider has a third rack 3421, and a movable guide roller 3212 is fixed to the fifth slider. Through the meshing of the third rack 3421 and the third gear 3441, the adhesive-pulling finger 341 can follow the fifth slider along the fifth slide rail. This enhances the control precision of the adhesive-pulling finger 341's movement distance, thereby improving the control precision of the tape C's movement distance. For example, during tape wrapping, the starting position of the tape C on the workpiece D can be precisely controlled. Exemplarily, the third drive motor may include a servo motor to further improve the control precision of the tape C's movement distance.

[0206] In some embodiments not shown, the glue preparation mechanism 35 further includes a second lead screw, a second movable seat 342 which is a sixth slider, a second guide 343 which is a sixth slide rail, a second drive 344 which is a fourth drive motor, the sixth slider is threadedly connected to the second lead screw, and the fourth drive motor is drivenly connected to the second lead screw to drive the sixth slider to slide on the sixth slide rail.

[0207] The sixth slider is threadedly connected to the second lead screw, converting the rotational motion of the second lead screw into the linear motion of the sixth slider. Thus, the sixth slider can drive the adhesive-pulling finger 341 to move along the sixth slide rail. For example, the fourth drive motor may include a servo motor to further improve the control accuracy of the tape C's movement distance.

[0208] In some embodiments not shown, the second movable seat 342 is a second gear seat with a fourth gear, the second guide 343 is a fourth rack, the second drive member 344 is a fourth drive cylinder, the second gear seat is meshed with the fourth rack, and the fourth drive cylinder is driven by the second gear seat.

[0209] The second gear seat has a fourth rack, and the movable guide roller 3212 is fixed to the second gear seat. Through the meshing of the fourth rack and the fourth gear, the adhesive-pulling finger 341 can follow the second gear seat along the fourth rack. This enhances the control precision of the adhesive-pulling finger 341's movement distance, thereby improving the control precision of the tape C's movement distance. For example, during tape wrapping, the starting position of the tape C on the workpiece D can be precisely controlled. Exemplarily, the fourth drive cylinder can include a drive cylinder, a drive hydraulic cylinder, or a drive electric cylinder to reduce production costs. The fourth drive cylinder can also include a finger cylinder to improve movement accuracy and stability.

[0210] In some embodiments, please refer to Figures 13-14 The adhesive feeding device 30 also includes an identification component 36 for identifying the usage status of the adhesive tape C.

[0211] By identifying the usage status of tape C by the identification component 36, the amount of tape C used can be determined, so as to control the length of tape C used for wrapping each workpiece D, and can be replaced in time when tape C is about to run out.

[0212] In some embodiments, the identification component 36 includes a counter 361 disposed on the adhesive preparation mechanism 35 for counting the number of movements of the movable guide roller 3212 to calculate the length of the adhesive tape C used.

[0213] Counter 361 is used to calculate the distance the movable guide roller 3212 moves to determine the length of tape C used.

[0214] Understandably, the counter 361 can be set along the first guide 352, that is, in the same direction as the moving direction of the movable guide roller 3212, so that the length of the tape C used can be determined when the tape C moves along the first guide 352 following the movable guide roller 3212.

[0215] In this embodiment, the counter 361 facilitates the control of the travel length of the tape C. For example, it controls the amount of tape C used to coat a workpiece D, or ensures that the amount of tape C used in a single coat of the same batch of workpieces D is the same. Simultaneously, the counter 361 can also determine the total length of tape C used, allowing for timely monitoring of the tape C's usage status and prompt replacement.

[0216] In some embodiments, the identification component 36 includes an optical fiber sensor 362, which is configured corresponding to the unwinding mechanism 31 to monitor the usage status of the tape C on the unwinding mechanism 31.

[0217] For example, the fiber optic sensor 362 is disposed diagonally above the unwinding mechanism 31 to obtain the usage status of the tape C.

[0218] For example, the identification component 36 also includes a mounting bracket on which the fiber optic sensor 362 is mounted, located above the unwinding mechanism 31.

[0219] In this embodiment, the fiber optic sensor 362 can monitor the usage status of the tape C in a timely manner so that it can be replaced promptly.

[0220] In some embodiments, the identification component 36 includes a counter 361 and an optical fiber sensor 362 to improve the redundancy of detection, so that if either the counter 361 or the optical fiber sensor 362 is damaged, the usage status of the tape C cannot be detected in time.

[0221] In some embodiments, please refer to Figures 30-33 The adhesive applicator 40 includes a first pressing assembly 41 and a first driving assembly 42. The first pressing assembly 41 is used to press the adhesive tape C onto the workpiece D; the first driving assembly 42 is drivenly connected to the first pressing assembly 41 so that the first pressing assembly 41 can move.

[0222] The first pressing assembly 41 is used to press the tape C onto the workpiece D located at the overcoating station E. Exemplarily, the first pressing assembly 41 includes a first abutting member 411 and a first abutting seat 412. The first abutting seat 412 is used to mount the first abutting member 411, which abuts against the tape C. The first abutting member 411 is connected to a drive assembly via the first abutting seat 412. Exemplarily, the first abutting member 411 is an abutting wheel that can roll on the first abutting seat 412, with the arcuate surface of the abutting wheel facing the workpiece D. This improves the adhesion between the tape C and the workpiece D, thus improving the overcoating quality.

[0223] The first drive assembly 42 provides power to the first pressing assembly 41 to press the tape C onto the workpiece D. The method by which the first drive assembly drives the first pressing assembly 41 is not limited, as long as it enables the first pressing assembly 41 to press the tape C onto the workpiece D. For example, the first pressing assembly 41 can be moved by gear transmission, chain transmission, screw transmission, or belt transmission.

[0224] In this embodiment, the first driving component 42 drives the first pressing component 41 to press the tape C onto the workpiece D to achieve adhesive wrapping.

[0225] In some embodiments, please refer to Figure 30 The first driving assembly 42 includes a sliding seat 421 and a third driving member 422. The first pressing assembly 41 is slidably disposed on the sliding seat 421. The third driving member 422 is drivenly connected to the first pressing assembly 41 so that the first pressing assembly 41 can move on the sliding seat 421 along the fifth direction Y3 or the sixth direction Y4. The fifth direction Y3 is opposite to the sixth direction Y4 and is perpendicular to the first direction X1.

[0226] The third driving member 422 provides power to move the pressing assembly along the fifth direction Y3 or the sixth direction Y4, so that the first pressing assembly 41 can move towards the workpiece D to press the tape C onto the workpiece D; or move away from the workpiece D so that the adhesive-pulling finger 341 can move smoothly along the first direction X1 or the second direction X2. Thus, the third driving member 422 causes the first pressing assembly 41 to press the tape C onto the workpiece D.

[0227] For example, the third direction Y1 and the fourth direction Y2 group are parallel to the fifth direction Y3 and the sixth direction Y4 group.

[0228] In some embodiments, please refer to Figure 30 The first driving component 42 includes a fourth driving member 423, which is drivenly connected to the sliding seat 421 so that the sliding seat 421 can drive the first pressing component 41 to move along the first direction X1 or the second direction X2.

[0229] The fourth drive member 423 is used to provide power for the pressing assembly to move along the first direction X1 or the second direction X2, thereby improving the adhesion tightness between the tape C pressed on the surface of the workpiece D and the workpiece D and increasing the adhesion length.

[0230] In some embodiments, please refer to Figure 1 and Figure 34 The coating equipment 100 also includes a pressing device 60, which is used to press the tape C onto the workpiece D during the coating process driven by the rotating device 20.

[0231] During the coating process of workpiece D, the pressing device 60 presses the tape at localized locations on workpiece D to improve the coating effect. For example, when workpiece D is a square battery cell, the pressing device 60 applies pressure to the tape at corners or large surfaces of the battery cell to improve the coating effect and reduce gaps between the tape and the battery cell in these areas, as well as the appearance of bumps or bulges on the tape.

[0232] In some embodiments, please refer to Figure 34 The pressing device 60 includes a second pressing assembly 61 and a second driving assembly 62. The second pressing assembly 61 is used to press the tape C onto the workpiece D during the overmolding process; the second driving assembly 62 is drivenly connected to the second pressing assembly 61, enabling the second pressing assembly 61 to rotate to adapt to the rotational position of the workpiece. The second pressing assembly 61 is used to press the tape C onto the workpiece D during the overmolding process. Exemplarily, the second pressing assembly 61 includes a second abutment 611 and abutment seat 612. The second abutment seat 612 is used to mount the second abutment 611, which can abut against the tape C on the workpiece D. Exemplarily, the second abutment 611 is an abutment wheel, which can roll on the second abutment 611, with the arcuate surface of the abutment wheel facing the workpiece D. In this way, the adhesion between the tape C and the workpiece D can be improved, and the overmolding quality can be improved.

[0233] The second abutment 611 can compact the tape C in the middle and around the corners of the workpiece D during the coating process, further improving the adhesion between the tape C and the workpiece D.

[0234] The second drive assembly 62 provides power to the second pressing assembly 61 to press the tape C onto the workpiece D. The method by which the second drive assembly 62 drives the second pressing assembly 61 is not limited, as long as it enables the second pressing assembly 61 to press the tape C onto the workpiece D. For example, the second drive assembly 62 includes a finger cylinder, which is drivenly connected to the second abutment seat 612.

[0235] Understandably, the second abutment 611 can rotate to reduce the resistance to the rotation of the workpiece D. While contacting the adhesive tape C on the surface of the workpiece D, the rotation of the second abutment 611 can enhance the adhesion between the adhesive tape C and the workpiece D.

[0236] In this embodiment, as the workpiece D rotates, the distance between the outer contour of the workpiece D and the second abutment 611 will change. By driving the second pressing component 61 to rotate through the second driving component 62, the second abutment 611 can press the tape C onto the workpiece D, thereby improving the adhesion between the tape C and the workpiece D and improving the coating quality.

[0237] In some embodiments, please refer to Figures 35-37The shearing device 50 includes a vertical plate 51 and a scissor mechanism 52. The vertical plate 51 has a first adjustment hole 51a; the scissor mechanism 52 includes a telescopic component 521, scissors 522, a first connector 523, and a first locking member. The telescopic component 521 is drivenly connected to the scissors 522 to drive the scissors 522 to extend or retract. The first connector 523 is disposed on the telescopic component 521. The first connector 523 passes through the first adjustment hole 51a. The scissor mechanism 52 can move a preset distance or rotate a preset angle relative to the vertical plate 51. The first locking member is connected to the first connector 523 to lock the position of the scissor mechanism 52 on the vertical plate 51.

[0238] The upright plate 51 is used to mount the scissor mechanism 52, and the upright plate 51 and the scissor mechanism 52 can be movably and rotatably connected. Locking the position of the scissor mechanism 52 refers to adjusting or changing the position or orientation of the scissors 522.

[0239] The scissor mechanism 52 is used to cut the tape C. The telescopic component 521 can extend the scissors 522 to cut the tape C, or retract the scissors 522. The telescopic component 521 can drive the scissors 522 to extend or retract in any way, as long as it allows the scissors 522 to move in a straight line.

[0240] The scissor mechanism 52 is mounted on the upright plate 51 via a first connector 523. The first connector 523 is movable within the first adjustment hole 51a, which allows the scissor mechanism 52 to move a preset distance or rotate a preset angle relative to the upright plate 51. For example, the telescopic assembly 521 includes a connecting plate 5211, and the first connector 523 passes through the first adjustment hole 51a and is connected to the connecting plate 5211, so that the scissor mechanism 52 is mounted on the upright plate 51.

[0241] The first locking member is used to lock the first connecting member 523, so that the scissor mechanism 52 and the upright plate 51 are relatively fixed. The number of the first locking members can be equal to or less than the number of the first connecting members 523. When the number of the first connecting members 523 is large, some of the first connecting members 523 may not need to be locked by the first locking members. After the threads of some of the first connecting members 523 are stripped and damaged, the first locking members can be locked onto the other first connecting members 523. When adjusting the position of the scissor mechanism 52 on the upright plate 51, the first locking member releases the fixing effect on the first connecting member 523, and the scissor mechanism 52 and the upright plate 51 can move relative to each other. The scissor mechanism 52 can move a preset distance or rotate a preset angle relative to the upright plate 51. After the adjustment is completed, the first locking member fixes the first connecting member 523 to the scissor mechanism 52 and the upright plate 51. The scissor mechanism 52 is fixed to the upright plate 51 so that the scissors 522 can stably cut the tape C.

[0242] In this embodiment, the first connecting member 523 enables a movable connection between the upright plate 51 and the scissor mechanism 52, allowing adjustment of the cutting posture of the scissor mechanism 52 and the position and angle of the scissors 522 relative to the tape C when cutting. The first locking member allows the locking of the first connecting member 523 to be released before adjustment, enabling the scissors mechanism 52 to move relative to the upright plate 51. After adjustment, the first connecting member 523 can be locked, ensuring the scissors mechanism 52 can stably cut the tape C on the upright plate 51. The telescopic component 521 allows the scissors 522 to extend and retract to the position for cutting the tape C. This allows for precise control of the cut size and angle of the tape C, facilitating subsequent hemming.

[0243] For example, the first connector 523 and the first locking member are threaded together. For instance, the first connector 523 includes a stud and the first locking member includes a nut, which facilitates disassembly and assembly and improves the adjustment efficiency of the scissor mechanism 52.

[0244] In some embodiments, see Figure 35 The first adjustment hole 51a is divided into two, three, four or more arc-shaped holes 51a1 distributed on a concentric circle. The number of first connectors 523 is the same as the number of arc-shaped holes 51a1, and a first connector 523 is inserted into each arc-shaped hole 51a1.

[0245] In this embodiment, the first connector 523 moves within the corresponding arc-shaped hole 51a1. Since the first connector 523 is mounted on the telescopic assembly 521, the scissor mechanism 52 can move a preset distance or rotate a preset angle following the first connector 523 to adjust the position and orientation of the scissor mechanism 52. For example, the width of the arc-shaped hole 51a1 is greater than the diameter of the first connector 523, allowing the scissor mechanism 52 to rotate with the first connector 523 and also move a small distance horizontally.

[0246] For example, the arc-shaped holes 51a1 are spaced apart on their respective circumferences. For instance, when there are two arc-shaped holes 51a1, the two arc-shaped holes 51a1 are arranged opposite each other to improve connection stability.

[0247] In some embodiments, the width of the arc-shaped hole 51a1 is adapted to the diameter of the first connector 523.

[0248] By limiting the width of the arc-shaped hole 51a1, the first connecting member 523 can move within the arc-shaped hole 51a1. In this embodiment, the scissor mechanism 52 can rotate a preset angle with the first connecting member 523, but the whole cannot move in the horizontal direction.

[0249] It is understandable that the width of the arc-shaped hole 51a1 is greater than or equal to the diameter of the first connector 523, so that the first connector 523 can be smoothly inserted into the arc-shaped hole 51a1 and move a preset distance or rotate a preset angle within the arc-shaped hole 51a1.

[0250] In some embodiments, see Figure 33 The first adjustment hole 51a is divided into at least two strip holes 51a2 with intervals. The number of first connectors 523 is the same as the number of strip holes 51a2. Each strip hole 51a2 has a first connector 523 inserted through it.

[0251] In this embodiment, the first connector 523 moves within the corresponding strip hole 51a2. Since the first connector 523 is disposed on the telescopic component 521, the scissor mechanism 52 can move a preset distance or rotate a preset angle with the first connector 523 to adjust the position and posture of the scissor mechanism 52.

[0252] For example, there are six strip holes 51a2, which are divided into three groups along the extension and retraction direction of the scissors 522. This can improve the stability of the connection between the upright plate 51 and the scissor mechanism 52.

[0253] In some embodiments, the strip-shaped hole 51a2 is arranged in a horizontal direction.

[0254] In this way, the first connector 523 can drive the scissor mechanism 52 to move horizontally within the strip hole, moving a preset distance to adjust the cutting position of the tape C.

[0255] In some embodiments, the width of the strip hole 51a2 is greater than the diameter of the first connector 523.

[0256] This allows the first connector 523 to have room to move within the strip hole 51a2, so that the first connector 523 can rotate at a preset angle.

[0257] In some embodiments, the scissor mechanism 52 moves 5-15 mm in the horizontal direction.

[0258] The horizontal movement distance of the scissor mechanism 52 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm, etc. Thus, by controlling the movement range of the scissor mechanism 52, the cutting position of the scissors 522 can be controlled, ensuring the tape C is kept to a suitable size. This reduces the adverse effects of excessively long or short remaining tape C on the workpiece D after tape C is applied, and facilitates subsequent edge folding.

[0259] In some embodiments, please refer to Figure 35 The scissor mechanism 52 can be adjusted in an angle range of 45-60°.

[0260] The scissor mechanism 52 is adjustable at an angle α, which can be 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, or 60°, etc. Thus, by controlling the adjustment angle of the scissor mechanism 52, the cutting angle of the scissors 522 can be controlled, ensuring the angle of the cut tape C is within a suitable range, facilitating subsequent folding.

[0261] It is understandable that the angle adjusted by the scissor mechanism 52 is the angle between the scissor mechanism 52 and the horizontal plane. For example, when the upright plate 51 includes a vertical part arranged in the vertical direction and a horizontal part arranged in the horizontal direction, the acute angle formed between the horizontal part and the scissor 522 is α.

[0262] In some embodiments, please refer to Figures 38-41 The coating equipment 100 also includes a folding device 70, which is used to fold the tape C on the workpiece D after it has been cut by the shearing device 50.

[0263] The folding device 70 is used to fold the tape C on the workpiece D in half after cutting the tape C, so that the tape C can be removed later. It is understood that the folded direction of the tape C faces upwards to avoid affecting the painting of the workpiece D. For example, when the workpiece D is a battery cell, the battery cell includes a top cover and a housing, and the adhesive coating is located between the top cover and the housing. The folded edge of the tape C faces towards the top cover to avoid affecting the painting of the housing surface. After the housing is painted, force is applied at the folded edge of the tape C to remove the tape, facilitating subsequent welding of the top cover to the housing.

[0264] In some embodiments, please refer to Figure 38 The folding device 70 includes a mounting base 71, a sixth drive member 72, a seventh drive member 73, a reference shaft 74, and a folding plate 75. The mounting base 71 has a first adsorption part 71a capable of adsorbing the tape C; the sixth drive member 72 can drive the mounting base 71 to move closer to or away from the conveyed tape C; the seventh drive member 73 is disposed on the mounting base 71; the seventh drive member 73 is drivenly connected to the reference shaft 74 so that the reference shaft 74 can rotate; the folding plate 75 is connected to the reference shaft 74 and has a second adsorption part 75a capable of adsorbing the tape C. The second adsorption part 75a can follow the rotation of the reference shaft 74 and then fit against the first adsorption part 71a to fold the tape C.

[0265] Mounting base 71 provides a mounting base for the seventh drive component 73, the reference shaft 74, and the folding plate 75.

[0266] The sixth driving component 72 is used to provide power for the movement of the mounting base 71, so that the mounting base 71 drives the folding plate 75 to move, so that the folding device 70 can be close to the workpiece D for folding, or the folding device 70 can be far away from the workpiece D to reduce the possibility of interfering with the adhesive application device 40.

[0267] The first adsorption part 71a and the second adsorption part 75a can adsorb the tape C, preparing for the tape C to be folded so that the tape C can adhere to the surface of the folding plate 75 and move with the folding plate 75. The reference shaft 74 drives the folding plate 75 to rotate, so that the second adsorption part 75a is in contact with the first adsorption part 71a, and the tape C is folded.

[0268] In this embodiment, during the application of adhesive, the sixth driving member 72 drives the mounting base 71 away from the tape C to avoid interfering with the application of adhesive by the adhesive applicator 40 and to reduce the possibility of interfering with the rotation of the workpiece D; during the folding process, the seventh driving member 73 drives the reference shaft 74 to rotate, thereby rotating the folding plate 75 and causing the second adsorption part 75a to adhere to the first adsorption part 71a, thus achieving the folding of the tape C.

[0269] For example, both the first adsorption part 71a and the second adsorption part 75a are connected to a cylinder or an air pump via a connecting pipe. The cylinder or air pump is used to provide power for the first adsorption part 71a and the second adsorption part 75a to adsorb the tape C.

[0270] For example, the folding device 70 also includes a seventh slide rail 77, to which the mounting base 71 is slidably connected. The slidable connection between the mounting base 71 and the seventh slide rail 77 allows the folding plate 75 to move toward or away from the workpiece D.

[0271] For example, the seventh slide rail 77 is arranged along the third direction Y1 or the fourth direction Y2.

[0272] In some embodiments, please refer to Figure 38 and Figure 39 The mounting base 71 includes a base body 711, a second connecting member 712, a mounting plate 713, and a second locking member. A sixth driving member 72 is drivenly connected to the base body 711; the second connecting member 712 is disposed on the base body 711; a seventh driving member 73 is disposed on the mounting plate 713, which has a second adjustment hole 713a; wherein, the second connecting member 712 passes through the second adjustment hole 713a, and the mounting plate 713 can rotate relative to the base body 711 by a preset angle; the second locking member is connected to the second connecting member 712 to lock the position of the mounting plate 713 on the base body 711.

[0273] Understandably, see Figure 38 The mounting plate 713 rotates clockwise by a preset angle relative to the base 711 so that after the tape C is folded, the resulting laminated tape C is folded upwards to avoid affecting the painting of the workpiece D.

[0274] In some embodiments, the mounting plate 713 can rotate relative to the base 711 by an angle of 0 to 15°.

[0275] For example, the mounting plate 713 can rotate relative to the base 711 by an angle β, which can be 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, or 15°.

[0276] It is understandable that when the reference axis 74 is perpendicular to the horizontal direction along the vertical Z, the angle of rotation of the mounting plate 713 relative to the base 711 is 0°. When the mounting plate 713 rotates clockwise relative to the base 711, the angle of rotation of the mounting plate 713 relative to the base 711 gradually increases, and at the same time, the acute angle formed by the reference axis 74 and the horizontal direction gradually decreases, and the end of the reference axis 74 gradually approaches the base 711.

[0277] In this embodiment, by controlling the rotation angle of the mounting plate 713 relative to the base 711, the reference shaft 74 drives the folding plate 75 to rotate, thereby controlling the folding angle to fold the tape C into a suitable angle so that the tape C can be cleaned after the subsequent painting is completed.

[0278] In some embodiments, please refer to Figure 38 The folding device 70 also includes a fixing seat 76, which is disposed on the mounting seat 71. The fixing seat 76 includes two ear plates 761 with mounting holes, a reference shaft 74 passing through the mounting holes, and a folding plate 75 located between the two ear plates 761 and connected to the reference shaft 74.

[0279] In this embodiment, a reference shaft 74 passes through the fixed base 76 and the folding plate 75. A portion of the folding plate 75 is located between two ear plates 761, which limit the movement of the folding plate 75. The reference shaft 74 passes through the mounting hole and is fixedly connected to another portion of the folding plate 75, allowing the reference shaft 74 to rotate more smoothly and enabling the folding plate 75 to stably follow the rotation of the reference shaft 74, thereby achieving the folding effect.

[0280] In some embodiments, please refer to Figure 1 The coating equipment 100 also includes a worktable 80, and a conveying device 10, a rotating device 20, a glue feeding device 30, a glue applying device 40, a cutting device 50, a folding device 70, and a pressing device 60 are all mounted on the worktable 80.

[0281] In this embodiment, the conveying device 10, rotating device 20, glue feeding device 30, glue applying device 40, and shearing device 50 are all mounted on the workbench 80. This allows for the reasonable arrangement of the positions of each mechanism according to the glue coating process requirements of the workpiece D, resulting in a smaller space occupied by the glue coating equipment 100. It can be sold as a complete set of assembled equipment, or the workbench 80 has interfaces or mounting holes for installing each device, facilitating quick installation at the factory site.

[0282] Understandably, the coating equipment 100 of this application may also exclude the workbench 80, and the conveying device 10, rotating device 20, glue feeding device 30, glue applying device 40, cutting device 50, folding device 70 and pressing device 60 may be installed on the foundation or platform of the factory.

[0283] This application also provides an overcoating system 1000; please refer to [link to relevant documentation]. Figure 1 The equipment includes the coating equipment 100 and the conveying channel 200, which are included in any of the above. The conveying channel 200 is used to convey the workpiece D and is located close to the coating equipment 100 so that the conveying device 10 can move the workpiece D from the conveying channel 200 to the rotating device 20 or move the workpiece D from the rotating device 20 to the conveying channel 200.

[0284] In this embodiment, the conveying channel 200 can convey the workpiece D to be coated to the position where the conveying device 10 can clamp the workpiece D, and can also convey the coated workpiece D to the next process.

[0285] It is understood that one or more conveyor channels 200 may be provided. For example, three conveyor channels 200 are provided to improve conveying efficiency. The conveying direction of the conveyor channels 200 may be set along the longitudinal direction Y.

[0286] For example, the distance between the two conveying channels 200 is the same as the distance between the two sets of clamping mechanisms 12 on the conveying device 10. In this way, the conveying device 10 can grab a workpiece D to be coated on one conveying channel 200 while placing a workpiece D already coated on another conveying channel 200.

[0287] In some embodiments, the conveying channel 200 includes a loading position 201 and a buffer position 202. The loading position 201 is used for loading workpiece D; the buffer position 202 is used for buffering workpiece D conveyed by the loading position 201, and the conveying device 10 transports workpiece D from the buffer position 202 to the rotating device 20 or from the rotating device 20 to the buffer position 202.

[0288] In this embodiment, the buffer bit 202 can buffer multiple workpieces D to be coated, so that the conveying device 10 can continuously convey workpieces D to improve coating efficiency.

[0289] This application also provides a method for handling workpiece D; please refer to [link to relevant documentation]. Figure 42 Applied to the above-mentioned coating equipment 100, the handling method includes:

[0290] S1: The first set of gripper assemblies picks up the glued workpiece from the rotating device;

[0291] S2: The second set of gripper assemblies places the workpiece to be coated onto the rotating device;

[0292] S3: Move the gripping mechanism to the corresponding position on the conveyor channel;

[0293] S4: The second set of gripper assemblies grips the workpiece to be coated from the conveyor channel;

[0294] S5: The first set of gripper assemblies places the glued workpiece onto the conveyor belt;

[0295] S6: Move the gripping mechanism to the corresponding position of the rotating device.

[0296] In this embodiment, by simultaneously transporting the coated workpiece D and the workpiece D to be coated by two sets of gripper assemblies 121, the transport device 10 can continuously transport the workpiece D to be coated onto the rotating device 20, while simultaneously gripping the coated workpiece D. When transporting the coated workpiece D to the conveying channel 200, the workpiece D to be coated can be gripped simultaneously, thus improving the transport efficiency of the transport device 10 and consequently improving the coating efficiency. This avoids the situation where a single gripper assembly 121 has to transport both the coated workpiece D and the workpiece D to be coated, and can only transport one workpiece D at a time, affecting the transport efficiency.

[0297] It is understandable that the sequence of steps in the above-described handling method can be adapted to meet specific needs. For example, when the coating equipment 100 starts operating, the above method can be to first perform step S4, then sequentially perform steps S6, S2, and S3, completing one transfer of the workpiece D to be coated from the conveyor channel 200 to the waiting position F of the rotating device 20. The rotating device 20 then rotates to move the workpiece D to the coating position E for coating. During the coating process of the first workpiece D, the handling device 10 repeats the steps of the first transfer of the workpiece D to be coated, transferring the second workpiece D to the corresponding position of the rotating device 200 from the conveyor channel 200. After the first workpiece D completes the coating, it is transferred to the waiting position F. The handling device 10 can operate cyclically according to the sequence of steps S1 to S6.

[0298] This application also provides another method for handling workpiece D, please refer to [link to relevant documentation]. Figure 43 Applied to the above-mentioned coating equipment 100, the handling method includes:

[0299] T1: The first set of gripper assemblies picks up the glued workpiece from the rotating device;

[0300] T2: Rotate the first set of gripper assemblies to rotate the glued workpiece by a preset angle;

[0301] T3: Rotate the second set of gripper assemblies to rotate the workpiece to be coated by a preset angle;

[0302] T4: The second set of gripper assemblies places the workpiece to be coated onto the rotating device;

[0303] T5: Move the gripping mechanism to the corresponding position on the conveyor channel;

[0304] T6: The second set of gripper assemblies grips the workpiece to be coated from the conveyor channel;

[0305] T7: The first set of gripper assemblies places the glued workpiece onto the conveyor belt;

[0306] T8: Move the clamping mechanism to the corresponding position of the rotating device.

[0307] In this embodiment, both the rotating device 20 and the clamping mechanism 12 are rotatable. Before the clamping mechanism 12 clamps the workpiece D on the rotating device 20, the rotating device 20 and the clamping mechanism 12 rotate to mutually compatible directions so that the clamping can smoothly clamp the workpiece D.

[0308] It is understandable that the sequence of steps in the above handling method can be adapted to meet specific needs.

[0309] Understandably, the orientation of workpiece D changes before and after the coating process. For example, when coating a square-shell battery cell, the coating begins from the short side, with the short side facing the coating equipment. After the cell rotates once for coating, it stops with the long side facing the coating equipment. To ensure that the conveying device 10 can smoothly place the coated workpiece D from the rotating device 20 onto the conveyor channel 200, the workpiece D on the rotating device 20 needs to be rotated to the same orientation as the workpiece D on the conveyor channel 200. Similarly, to ensure that the workpiece D to be coated, which is picked up by the conveying device 10 from the conveyor channel 200, can be smoothly placed onto the rotating device 20, the workpiece D on the gripping mechanism 12 also needs to be rotated to the same orientation as the workpiece D placed on the rotating device 20.

[0310] Understandably, to improve coating efficiency, the workpiece D to be coated is rotated by the rotating device 20 to the waiting station F, during which time its direction is switched to a direction compatible with the conveyor channel 200. Similarly, the conveying device 10, during the process of conveying the battery cell to be coated to the waiting station F, switches its direction to a direction compatible with the rotating device 20. This reduces waiting time and improves coating efficiency.

[0311] Taking a specific embodiment as an example, a portion of the coating process of the coating equipment 100 in this application will be described. For ease of explanation, in this embodiment, there are two conveying channels 200, used for loading and unloading respectively. The conveying channel 200 used for loading is located near the coating equipment. For the sake of description, the conveying channel 200 located near the coating equipment is referred to as the first conveying channel, and the other conveying channel 200 is referred to as the second conveying channel.

[0312] It should be noted that the following coating process is for illustrative purposes only and is not intended to be sequential. In order to form a continuous coating process and shorten the process time, some steps may be performed simultaneously.

[0313] 1) The first conveying channel conveys workpiece D.

[0314] Workpiece D is fed to the loading position 201 of a first conveying channel, and then moves from the loading position 201 to the buffer position 202.

[0315] 2) The conveying device 10 conveys the workpiece D to be coated with glue to the rotating device 20 and clamps the workpiece D that has been coated with glue; it then conveys the workpiece D that has been coated with glue to the conveying channel 200 and clamps the workpiece D to be coated with glue.

[0316] The horizontal movement mechanism 13 and the vertical movement mechanism 14 drive the gripping mechanism 12 to move above the conveying channel 200. The first set of gripper assemblies 121 holds the already coated workpiece D, while the second set of gripper assemblies 121 does not hold the workpiece D. At this time, the directions of both sets of gripper assemblies 121 are adapted to the conveying channel 200. Thus, the two sets of gripper assemblies 121 can respectively grip the workpiece D to be coated from the first conveying channel and place the already coated workpiece D on the second conveying channel.

[0317] The horizontal movement mechanism 13 and the vertical movement mechanism 14 drive the clamping mechanism 12 to move, so that the first set of gripper assembly 121 holding the glue-coated workpiece D is placed to the second conveying channel, while the second set of gripper assembly 121 clamps the workpiece D to be glue-coated on the first conveying channel.

[0318] The horizontal movement mechanism 13 and the vertical movement mechanism 14 drive the clamping mechanism 12 to move above the waiting station F, so that the first set of gripper assembly 121 clamps the workpiece D that has been coated with glue. The horizontal movement mechanism 13 and the vertical movement mechanism 14 drive the clamping mechanism 12 to move, so that the second set of gripper assembly places the workpiece D to be coated with glue on the waiting station F.

[0319] The horizontal movement mechanism 13 and the vertical movement mechanism 14 drive the clamping mechanism 12 to move laterally above the conveying channel 200. The second set of gripper assembly 121 clamps the workpiece D to be coated with glue from the first conveying channel, and the first set of gripper assembly 121 places the coated workpiece D on the second conveying channel.

[0320] 3) Workpiece D switches positions at waiting station F and coating station E.

[0321] The third rotary drive 24 drives the rotary table 21 to rotate, switching the already coated workpiece D in the coating station E to the waiting station F, and the workpiece D to be coated is switched to the coating station E.

[0322] The second rotary drive 23 drives the rotary fixture 22 to rotate, and the glued workpiece D switches to the direction that matches the gripper assembly 121.

[0323] 4) The glue feeding device 30 and the glue application device 40 work together to realize glue preparation, glue feeding and glue application.

[0324] Before applying the adhesive, the glue preparation mechanism 35 drives the movable guide roller 3212 to move along the third direction Y1 and the fourth direction Y2 to buffer the tape C before applying the adhesive. The first fixed finger 331 clamps the tape C, the second fixed finger 332 releases the tape C, and the movable guide roller 3212 is fixed. The glue pulling mechanism 34 pulls the tape C to move along the first direction X1 or the second direction X2 to adjust the tension of the tape C. When the second fixed finger 332 releases the tape C, the first fixed finger 331 clamps the tape C, and the glue pulling finger 341 pulls the tape C along the second direction X2 to the middle of the workpiece D on the rotating fixture 22 and the adhesive application device 40. The adhesive application device 40 presses the tape C onto the workpiece D. The rotating fixture 22 drives the workpiece D to rotate so that the tape C wraps around the workpiece D. The movable guide roller 3212 moves along the fourth direction Y2 in coordination with the rotation speed of the workpiece D to achieve glue delivery. When workpiece D is rotating to be coated with glue, the pressing drive 253 drives the pressing member 252 to move towards or away from workpiece D, so that workpiece D on the rotating fixture 22 is pressed down when it is rotating and being coated with glue.

[0325] 5) After coating, the shearing device 50 cuts the tape C, and the folding device 70 folds the tape C.

[0326] Release the first locking member from locking the first connecting member 523, and adjust the position of the scissor mechanism 52 so that the angle between the scissor mechanism 52 and the horizontal plane is 50°. Lock the first connecting member 523 with the first locking member to fix the scissor mechanism 52 and the upright plate 51 relatively. The telescopic assembly 521 drives the scissors 522 to extend and retract to the position for cutting the tape C, cutting the tape C. After cutting, the scissors 522 retracts. After cutting the tape C, the folding device 70 folds the tape C on the workpiece D in half, with the folded edge of the tape C facing the top cover. After the housing is painted, force is applied to the folded edge of the tape C to tear off the tape.

[0327] In another specific embodiment of the coating process, after the workpiece D is coated, its orientation at the coating station E is perpendicular to the orientation of the conveying channel 200. After gripping the coated workpiece D, the gripper assembly 121 is rotated by a preset angle to a direction compatible with the conveying channel 200, for example, by 90°; before placing the workpiece D to be coated, the gripper assembly 121 is rotated by a preset angle to a direction compatible with the rotating device 20, for example, by 90°.

[0328] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0329] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
