Description

[0002] On the energy storage battery module production line, each module is usually composed of 6 to 11 cells. The cell surfaces at both ends of the module need to be pasted with special-shaped insulating sheets to protect the cell surface. The traditional method is to manually peel off the base film on the insulating sheet and then manually paste the insulating sheet on the cell. Since the special-shaped insulating sheet is a plastic sheet with a hard backing and a strong adhesive, there are action sequence requirements for pasting, and it needs to be pressed into place at one time. Once the surface is pasted, it is difficult to tear it off and re-paste it. Therefore, manual pasting currently has many pasting steps, large pasting deviation, and difficulty in secondary correction, which leads to low pasting efficiency and high labor costs for insulating sheets.

[0054] The present invention integrates the material storage mechanism 2, the transfer mechanism 3, the film tearing mechanism 4, the material positioning mechanism 5, the battery cell positioning mechanism 6, and the pasting mechanism 7 in the frame 1, and has a compact structure and occupies a small space. It can automatically and integrally realize the taking of the insulating sheet 8, the peeling of the base film on the insulating sheet 8, and the pasting of the insulating sheet 8 to the battery cell 9. Automatic pasting is used instead of manual pasting, which can avoid the risk of pasting deviation and easy secondary correction during manual pasting, can ensure the uniformity of the pasting quality of the insulating sheet 8, reduce labor costs and improve the pasting efficiency of the insulating sheet 8.

[0055] See also Fig.12 The current insulating sheet 8 adopts a three-sided bent special-shaped structure, the top surface of which fits the top surface of the battery cell 9, and the three bent side surfaces fit the three side surfaces of the battery cell 9 respectively.

[0056] See also Figure 2 As an embodiment of the present invention, the storage mechanism 2 also includes a storage push plate 23 arranged in the storage bin 21 and a pushing assembly arranged on the side of the storage bin 21. The pushing assembly drives the storage push plate 23 to rise and fall, and the insulating sheet 8 is placed on the storage push plate 23. The discharge port 22 is arranged above the storage push plate 23. The storage assembly lifts the insulating sheet 8 upward and lifts the topmost insulating sheet 8 to the discharge port 22, waiting for the transfer mechanism 3 to pick up the material. A silo door is provided on the side of the storage bin 21 away from the pushing assembly. The staff puts the stacked insulating sheets 8 on the storage push plate 23 through the silo door, or takes out the excess insulating sheets 8 from the storage bin 21.

[0057] As an embodiment of the present invention, the pushing assembly includes a pushing rack 24 arranged on the frame 1, a screw slide 25 arranged on the pushing rack 24, and a storage push plate 23 arranged at the driving end of the screw slide 25. The movement of the slider on the screw slide 25 can drive the storage push plate 23 to rise and fall, thereby driving the insulating sheet 8 to rise and fall in the storage bin 21. The screw slide 25 can be replaced by other driving components according to specific usage requirements, such as a cylinder, an oil cylinder, etc.

[0058] As an embodiment of the present invention, the storage mechanism 2 also includes a storage mounting plate 26 arranged on the frame 1, a storage cylinder 27 arranged on the storage mounting plate 26, and a storage moving plate 28 driven by the storage cylinder 27. A storage guide slider group 29 is provided between the storage mounting plate 26 and the storage moving plate 28. There are multiple storage bins 21, and the multiple storage bins 21 and the pushing rack 24 are all arranged on the storage moving plate 28. The storage cylinder 27 drives the storage moving plate 28 to move on the storage mounting plate 26 to realize the change of the positions of the multiple storage bins 21. Since the material picking position of the transfer mechanism 3 is fixed, the switching of the storage bins 21 is realized by adjusting the positions of the multiple storage bins 21. Taking two storage bins 21 as an example, the two storage bins 21 are respectively the first storage bin and the second storage bin. At the beginning, the discharge port of the first storage bin is 22 is located below the transfer mechanism 3. The transfer mechanism 3 takes materials from the first storage bin, and the second storage bin is in a waiting state. When the insulating sheets 8 in the first storage bin are taken out or are about to be taken out, the storage cylinder 27 drives the storage movable plate 28 to move, so that the discharge port 22 of the second storage bin is located below the transfer mechanism 3. At this time, the transfer mechanism 3 takes materials from the second storage bin, and the first storage bin is in a waiting state. The staff can replenish the insulating sheets 8 in the first storage bin in time. After the insulating sheets 8 in the second storage bin are taken out or are about to be taken out, the storage cylinder 27 drives the storage movable plate 28 to move, and the discharge port 22 of the first storage bin is located below the transfer mechanism 3 again, thereby realizing the switching between the first storage bin and the second storage bin, so that the storage mechanism 2 can be in a continuous working state, thereby improving the overall working rhythm.

[0059] As an embodiment of the present invention, the storage bin 21 is tilted to ensure that the insulating sheet 8 bent on three sides is staggered and stacked in the storage bin 21, so that the insulating sheet 8 at the top remains in a relatively horizontal state, which is convenient for the transfer mechanism 3 to absorb. Preferably, the inclination angle of the storage bin 21 is 30°, that is, the angle between the storage bin 21 and the storage movable plate 28 is 30°.

[0060] See also Figure 3As an embodiment of the present invention, the transmission assembly includes a transmission mounting frame 31 arranged on the frame 1, a track cylinder 32 arranged on the transmission mounting frame 31, and the suction cup assembly includes a suction cup mounting frame 33 arranged on the track cylinder 32, a suction cup cylinder 34 arranged on the suction cup mounting frame 33, and a transmission suction cup 35 arranged at the driving end of the suction cup cylinder 34. The track cylinder 32 drives the suction cup mounting frame 33, the suction cup cylinder 34 and the transmission suction cup 35 to move back and forth between the material storage mechanism 2 and the material positioning mechanism 5, and the suction cup cylinder 34 drives the transmission suction cup 35 to move back and forth between the material storage mechanism 2 and the material positioning mechanism 5. Lifting and lowering, the transmission suction cup 35 absorbs or puts down the insulating sheet 8. Preferably, a limiting component is provided near the film tearing mechanism 4. When the suction cup mounting frame 33 moves to the limiting component, the limiting component prevents the suction cup mounting frame 33 from continuing to move, so that the film tearing mechanism 4 can smoothly tear off the bottom film of the insulating sheet 8. When the film tearing is completed, the limiting component releases the restriction on the movement of the suction cup mounting frame 33, so that it continues to move toward the material positioning mechanism 5. Among them, the limiting component can use different devices according to specific usage requirements, such as blocking cylinders, photoelectric sensors, or position switches.

[0061] See also Figure 4 and Figure 5 As an embodiment of the present invention, the film tearing mechanism 4 includes a film tearing mounting frame 41 arranged on the frame 1, a first film tearing cylinder 42 arranged on the film tearing mounting frame 41, a film tearing moving plate 43 driven by the first film tearing cylinder 42, a film tearing bearing seat 44 arranged on the film tearing moving plate 43, a film tearing optical axis 45 passing through the film tearing bearing seat 44, a rotating cylinder 46 for driving the film tearing optical axis 45 to rotate, an optical axis bracket 47 arranged on the film tearing optical axis 45, a film tearing rotating plate 48 arranged on the optical axis bracket 47, a second film tearing cylinder 49 arranged on the film tearing rotating plate 48, and a film tearing clamping plate 40 arranged on the driving end of the second film tearing cylinder 49, and a film tearing portion 481 cooperating with the film tearing clamping plate 40 is provided at one end of the film tearing rotating plate 48 close to the film tearing clamping plate 40. Preferably, a film tearing guide slider group is provided between the film tearing moving plate 43 and the film tearing mounting frame 41. The film peeling mechanism 41 is actuated by the second film peeling cylinder 49, which drives the film peeling plate 40 to extend and separate from the film peeling portion 481, and then drives the film peeling plate 40 to retract and clamp one end of the bottom film on the insulating film 8 between the film peeling plate 40 and the film peeling portion 481. The rotating cylinder 46 drives the film peeling rotating plate 48 to rotate, and the first film peeling cylinder 42 is assisted to retract to peel off the bottom film. When the film peeling plate 40 is facing downward, the second film peeling cylinder 49 is controlled to drive the film peeling plate 40 to extend and separate from the film peeling portion 481, and the clamped bottom film is discarded. The first film peeling cylinder 42, the second film peeling cylinder 49 and the rotating cylinder 46 are reset to wait for the arrival of the next insulating film 8.

[0062] As an embodiment of the present invention, the first film-tearing cylinder 42 and the film-tearing movable plate 43 are both inclined, which can avoid the transfer mechanism 3 in the vertical direction and ensure that the transfer mechanism 3 will not interfere with or collide with the film-tearing mechanism 4 when carrying the insulating sheet 8 away, thereby improving the safety of use. If the first film-tearing cylinder 42 and the film-tearing movable plate 43 are vertically arranged, due to the inelasticity of the bottom film, the insulating sheet 8 will be subjected to a downward pulling force, causing the film-tearing mechanism 4 to tear the insulating sheet 8 off the transfer mechanism 3 during the film-tearing process, causing an abnormality. After the first film-tearing cylinder 42 and the film-tearing movable plate 43 are inclined, the bottom film can move in both the vertical and horizontal directions, and a preliminary film-tearing action is formed, thereby improving the smoothness of film-tearing, and also avoiding the insulating sheet 8 from falling, reducing the occurrence rate of abnormalities, and improving the stability and reliability of the film-tearing mechanism 4. Preferably, the inclination angle of the first film-tearing cylinder 42 and the film-tearing movable plate 43 is 45°, that is, the angle with the top surface of the insulating sheet 8 located on the transfer mechanism 3 is 45°.

Preferably, the positioning platform 51 is an anti-sticking positioning platform, which can effectively prevent the insulating sheet 8 from adhering to the surface of the positioning platform 51, affecting the adhesion of the insulating sheet 8, and avoiding unnecessary influence on the pasting of the insulating sheet 8. When working, the transfer mechanism 3 places the insulating sheet 8 on the positioning platform 51, and the positioning cylinder 53 drives the positioning push plate 52 to extend to arrange the insulating sheet 8 and move it to the set position, fix its position, and facilitate the pasting mechanism 7 to take the material.

[0064] As an embodiment of the present invention, the positioning platform 51 is rectangular, and its shape is the same as that of the insulating sheet 8. The positioning push plate 52 has a first plate and a second plate. The first plate and the second plate are perpendicular, that is, the first plate is parallel to one side of the positioning platform 51, and the second plate is parallel to the other side of the positioning platform 51. When the positioning push plate 52 is extended, the first plate and the second plate respectively contact one side of the insulating sheet 8 and push it toward the positioning platform 51, thereby realizing the positioning and arrangement of the insulating sheet 8.

[0065] As an embodiment of the present invention, there are two positioning cylinders 53 and two positioning push plates 52. The two positioning cylinders 53 are respectively arranged on both sides of the positioning platform 51.

The clamping claw 65 is driven to open and close by the clamping cylinder 64 to realize the clamping and releasing of the battery cell 9 and complete the clamping and fixing action of positioning the battery cell 9. Preferably, a plurality of clamping cylinders 64 and driving clamping claws 65 are provided on the positioning lifting plate 63, so that a plurality of battery cells 9 can be clamped and positioned at the same time, thereby improving work efficiency.

[0067] As an embodiment of the present invention, a limiter is provided on the positioning lifting plate 63, and the limiter is used to adjust the opening degree of the clamping cylinder 64, so that the clamping cylinder 64 can reach the opening degree suitable for grasping the battery cell 9, while avoiding unnecessary interference or collision between each other caused by excessive opening, thereby improving the safety of use, effectively reducing the overall working space, and improving the utilization rate of the working space.

[0069] During operation, the sticking suction cup 75 absorbs the insulating sheet 8. Driven by the four-axis robot 71, the sticking suction cup 75 carries the insulating sheet 8 to the top of the battery cell 9. The four-axis robot 71 slowly puts down the upper plate 72, the lower plate 73, the sticking suction cup 75 and the insulating sheet 8. When the top of the insulating sheet 8 contacts the battery cell 9, as the four-axis robot 71 continues to descend, the sticking suction cup 75 is pushed upward by the battery cell 9, and the lower plate 73 is forced to carry the insulating sheet 8 upward, and the roller 761 contacts and rolls the side of the insulating sheet 8. The present invention adsorbs the insulating sheet 8 by the sticking suction cup 75 and transports the insulating sheet 8 to the top of the battery cell 9 and aligns it with the battery cell 9 through the four-axis robot 71, and then rolls the insulating sheet 8 through the rolling assembly to make it stick to the surface of the battery cell 9, which can realize automatic sticking of the insulating sheet 8 and effectively improve the degree of automation. At the same time, the present invention adopts automatic sticking instead of manual sticking, which can avoid the risk of sticking deviation and easy secondary correction during manual sticking, can ensure the uniformity of the sticking quality of the insulating sheet 8, and improve the sticking efficiency.

A limiting ring 744 is provided at one end of the pasting optical axis 742 away from the pasting optical axis fixing seat 741. The pasting optical axis fixing seat 741 and the limiting ring 744 limit the pasting optical axis 742 to ensure that the pasting optical axis 742 can move in the linear bearing 743, avoid the separation and falling off of the pasting optical axis 742 and the linear bearing 743, and improve the overall working stability and reliability of the movable connecting member 74.

[0071] During operation: the lower plate 73 and the pasting optical axis fixing seat 741 are in the lowest position under the action of their own gravity. At this time, the limiting ring 744 contacts the upper plate 72 and limits the pasting optical axis 742. When the lower plate 73 is subjected to an upward thrust, the lower plate 73, the pasting optical axis fixing seat 741 and the pasting optical axis 742 all move upward until the pasting optical axis fixing seat 741 contacts the upper plate 72. At this time, the pasting optical axis fixing seat 741 limits the pasting optical axis 742 from continuing to move upward, that is, the lower plate 73 and the pasting optical axis fixing seat 741 are in the highest position.

[0072] As an embodiment of the present invention, a buffer is provided between the upper plate 72 and the lower plate 73, and the buffer can provide a certain buffer force for the movement of the lower plate 73, so as to prevent the lower plate 73 from rising at a very fast speed when subjected to force, causing the pasting optical axis fixing seat 741 to collide with the upper plate 72, thereby causing the pasting optical axis fixing seat 741 or the upper plate 72 to be damaged, and the service life of the pasting optical axis fixing seat 741 and the upper plate 72 can be improved. The buffer can adopt the following two structures:

[0073] Structure 1: The buffer member includes a spring 745 sleeved on the pasting optical axis 742, and the spring 745 is arranged between the linear bearing 743 and the pasting optical axis fixing seat 741;

[0074] Structure 2: The buffer member includes a plurality of elastic connectors arranged between the upper plate 72 and the lower plate 73, wherein the first end of the elastic connector is fixed on the upper plate 72, and the second end of the elastic connector is fixed on the lower plate 73, wherein the elastic connector can be a compression spring, a gas spring, a hydraulic spring, a rubber spring, etc.

[0075] As an embodiment of the present invention, a gasket 746 is provided between the linear bearing 743 and the limit ring 744. The function of the gasket 746 is similar to that of the buffer. When the limit ring 744 follows the sticking optical axis 742 to descend, the gasket 746 provides a buffering force to the limit ring 744, which can prevent the limit ring 744 from colliding with the upper plate 72 due to the fast descending speed, thereby causing damage to the limit ring 744 or the upper plate 72, and can improve the service life of the limit ring 744 and the upper plate 72.

[0076] As an embodiment of the present invention, there are multiple movable connecting parts 74, and the multiple movable connecting parts 74 are evenly distributed between the upper plate 72 and the lower plate 73, which can guide the lifting and lowering of the lower plate 73 at multiple positions, thereby improving the smoothness of the lifting and lowering of the lower plate 73; at the same time, the upper plate 72 and the lower plate 73 are connected by the movable connecting parts 74. By setting up multiple movable connecting parts 74, the connection stability between the lower plate 73 and the upper plate 72 and the balance of the lower plate 73 can be improved, thereby ensuring the working reliability and stability of the lower plate 73. Preferably, there are four movable connecting parts 74, and the four movable connecting parts 74 are evenly distributed.

[0077] See also Fig.11As an embodiment of the present invention, the rolling assembly 76 further includes a plurality of rotating shafts 762 and a plurality of roller arms 763. The roller 761 is arranged at a first end of the roller arm 763. The second end of the roller arm 763 is arranged on the rotating shaft 762 and rotates around the rotating shaft 762. The roller 761 can be expanded outward or contracted inward through the roller arm 763, and can be applied to insulating sheets 8 of various sizes, thereby improving the overall application range. An elastic member is arranged between the roller arm 763 and the upper plate 72, and the elastic member can provide the roller arm 763 with a certain elastic force. A pulling force is provided in the direction of the upper plate 72, so that the roller arm 763 continues to have an inward contraction force. Preferably, the elastic member is a tension spring 764. When the roller 761 contacts the side of the insulating sheet 8, under the action of the inward contraction force of the roller arm 763, the roller 761 can be attached to the insulating sheet 8 and roll the insulating sheet 8, so that the insulating sheet 8 is better attached to the battery cell 9, and the attaching quality of the insulating sheet 8 is improved. Among them, the following four structures can be adopted between the rotating shaft 762, the roller arm 763 and the roller 761:

[0078] Structure 1: The number of rotating shafts 762, roller arms 763 and rollers 761 is the same and corresponds one to one, that is, only one roller arm 763 is provided on one rotating shaft 762, only one roller 761 is provided on one roller arm 763, and each roller 761 is controlled by one roller arm 763;

[0079] Structure 2: The number of rotating shafts 762 and roller arms 763 is the same and corresponds one to one, that is, one rotating shaft 762 is provided with one roller arm 763; one roller arm 763 is provided with multiple rollers 761, that is, one roller arm 763 can control multiple rollers 761;

[0080] Structure three: a plurality of roller arms 763 are provided on a rotating shaft 762, i.e., the plurality of roller arms 763 can rotate around the same rotating shaft 762; the number of roller arms 763 is the same as that of rollers 761 and they correspond one to one, i.e., only one roller 761 is provided on a roller arm 763, and each roller 761 is controlled by one roller arm 763;

[0081] Structure 4: A plurality of roller arms 763 are provided on a rotating shaft 762 , that is, the plurality of roller arms 763 can rotate around the same rotating shaft 762 ; a plurality of rollers 761 are provided on a roller arm 763 , that is, the plurality of rollers 761 can be controlled by the roller arm 763 .

[0082] As an embodiment of the present invention, the shapes of the upper plate 72 and the lower plate 73 can be designed according to the specific shape of the insulating sheet 8. Since the commonly used insulating sheet 8 is a three-sided bent structure, the upper plate 72 and the lower plate 73 are both rectangular, and the rolling assembly 76 is arranged on the edges of the three sides of the upper plate 72. The rolling assembly 76 can roll the three sides of the insulating sheet 8 at the same time, which can not only improve the pasting efficiency of the insulating sheet 8, but also improve the pasting quality of the insulating sheet 8.

[0083] As an embodiment of the present invention, an adhesive suction cup pad 77 is provided at the bottom of the adhesive suction cup 75, which can effectively protect the adhesive suction cup 75, avoid direct collision between the adhesive suction cup 75 and the insulating sheet 8, and further avoid damage to the adhesive suction cup 75, thereby improving the service life of the adhesive suction cup 75.

[0084] In summary, the present invention provides a battery cell insulating sheet pasting device, which integrates a material storage mechanism 2, a transfer mechanism 3, a film tearing mechanism 4, a material positioning mechanism 5, a battery cell positioning mechanism 6, and a pasting mechanism 7 in a frame 1, has a compact structure, and occupies a small space; it can automatically and integrally realize the taking of the insulating sheet 8, the peeling of the bottom film on the insulating sheet 8, and the pasting of the insulating sheet 8 to the battery cell 9, and adopts automatic pasting instead of manual pasting, which can avoid the risk of pasting deviation and easy secondary correction during manual pasting, can ensure the uniformity of the pasting quality of the insulating sheet 8, and reduce the manual cost. The plurality of storage bins 21 can be switched in position, so that the storage mechanism 2 can be in a continuous working state, thereby improving the overall working rhythm; the storage bin 21 is tilted, which can ensure that the insulating sheet 8 bent on three sides is staggered and stacked in the storage bin 21, so that the insulating sheet 8 at the top is kept in a relatively horizontal state, which is convenient for the transfer mechanism 3 to absorb; the first film tearing cylinder 42 and the film tearing moving plate 43 are both tilted, which can avoid the transfer mechanism 3 in the vertical direction and ensure that the transfer mechanism 3 will not move when carrying the insulating sheet 8 away. The bottom film can move in both the vertical and horizontal directions to initially form a film-tearing action, thereby improving the smoothness of the film-tearing and avoiding the insulating sheet 8 from falling off, thereby reducing the abnormality rate and improving the stability and reliability of the film-tearing mechanism 4. The limiter is used to adjust the opening degree of the clamping cylinder 64, so that the clamping cylinder 64 can reach the opening degree that meets the requirements of grabbing the battery cell 9, while avoiding unnecessary interference or collision between each other caused by excessive opening, thereby improving the safety of use and effectively reducing the overall work. The insulating sheet 8 is adsorbed by the sticking suction cup 75 and transported to the top of the battery cell 9 and aligned with the battery cell 9 by the four-axis robot 71, and then the insulating sheet 8 is rolled by the rolling component to make it stick to the surface of the battery cell 9, which can realize automatic sticking of the insulating sheet 8 and effectively improve the degree of automation. At the same time, the present invention adopts automatic sticking instead of manual sticking, which can avoid the risk of sticking deviation and easy secondary correction during manual sticking, can ensure the uniformity of the sticking quality of the insulating sheet 8, and improve the sticking efficiency.
