Description

Technical Field

[0002] In the manufacturing process of double-row and single-row modules, gluing is an important step. It is mainly used to fix the battery cells to prevent them from moving or vibrating in the battery pack, thereby improving the reliability and safety of the battery pack.

[0003] For single-row modules, since the cells are only arranged on one side, you only need to apply tape on one side. This method of taping is relatively simple and can usually be completed using an automatic taping machine.

[0004] For double-row modules, since the cells are arranged in two rows, tape needs to be applied on both sides of the module. This method of applying tape is relatively complicated and requires higher precision and skills.

[0005] In the existing glue sticking method, considering the glue sticking accuracy problem, it is often adopted to grab the battery cell and flip it 90 degrees, and then use the glue sticking gripper to stick the glue pad from top to bottom. In this way, the battery cell needs to be transferred once more. This method has extremely high requirements on the production line when multiple battery cells are loaded or the cycle is high, resulting in high costs. In addition, one transfer will increase the instability of the equipment, thereby reducing the overall efficiency of the equipment. Summary of the invention

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 5As shown, a flippable battery cell side glue gripper comprises: a mounting bracket, a flipping bracket, a gripper assembly and a flipping driving mechanism; the mounting bracket comprises a first side plate 1, a second side plate 2 and a top plate 3, the top plate 3 is fixedly connected to the two side plates; a flipping bracket 4 is arranged between the first side plate 1 and the second side plate 2, and shafts 5 are respectively provided on both sides of the flipping bracket 4, and the two shafts 5 are respectively rotatably connected to the side plates on the corresponding sides; the gripper assembly is fixedly connected to the flipping bracket 4; the flipping driving mechanism is arranged on the outer side of the first side plate 1, and the flipping driving mechanism comprises a rotating rod 6, a linear displacement driving device 7 and a driving plate 8, the rotating rod 6 and the driving plate 8 are both arranged parallel to the first side plate 1, the fixed part of the linear displacement driving device 7 is fixedly connected to the outer wall of the first side plate 1, the movable part of the linear displacement driving device 7 is fixedly connected to the driving plate 8, the driving plate 8 is provided with a waist hole 9, one end of the rotating rod 6 is fixedly connected to the shaft 5, and the other end of the rotating rod 6 is vertically connected to a pin rod 10, and the pin rod 10 passes through the waist hole 9.

[0029] In the above scheme, the flipping gripper is used to grab the insulating rubber pad placed horizontally on the positioning tooling, flip the insulating rubber pad 90 degrees, and then vertically attach the insulating rubber pad to the surface of the battery cell; there is no need to use additional flipping equipment to flip the battery cell, and the flipping function is integrated in the existing gripper, which has the advantages of small space occupancy, lower cost, and no impact on production rhythm.

[0030] Specifically, the gripper assembly is fixedly connected to the flip bracket 4 and rotates with the flip bracket 4. The flip drive mechanism is used to drive and control the rotation of the flip bracket 4. When starting to grab, the gripper assembly is in a vertical state, and the gripper assembly grabs the horizontally placed insulating rubber pad vertically downward, and then the flip drive mechanism drives the flip bracket 4 to rotate 90 degrees, and the flip bracket 4 drives the gripper assembly to rotate 90 degrees, so that the gripper assembly is in a horizontal state. At this time, the insulating rubber pad becomes a vertical state, and then the mounting bracket is controlled to move horizontally toward the battery cell until the insulating rubber pad contacts the side wall of the battery cell, thereby realizing the gluing of the battery cell side.

[0031] Specifically, the working principle of the flipping drive mechanism is that the movable part of the linear displacement drive device 7 moves, driving the drive plate 8 to move linearly, and the drive plate 8 drives the pin rod 10 to move through the waist hole 9. Since the rotating rod 6 is fixedly connected to the shaft rod 5, the pin rod 10 can only drive the rotating rod 6 to rotate around the axis of the shaft rod 5. The rotating rod 6 drives the shaft rod 5 to rotate, and the shaft rod 5 drives the flipping bracket 4 to rotate; thus, the rotation angle of the flipping bracket 4 can be controlled by only controlling the stroke of the linear displacement drive device 7, which has low cost, simple and convenient control, simple debugging process, and is easy to operate automatically.

[0032] Preferably, the linear displacement drive device 7 is a cylinder. By selecting the cylinder model and adjusting the position of the waist hole 9 on the drive plate 8, the gripper assembly can be in a vertical state when the cylinder is at a minimum extension, and in a horizontal state when the cylinder is at a maximum extension, thereby further simplifying the control logic and facilitating operation.

[0033] In some embodiments, the gripper assembly includes a first connecting plate 11, a first mounting plate 12, a second mounting plate 13 and a plurality of nozzle connectors 14; one end of the first connecting plate 11 is connected to the flip bracket 4, and the other end of the first connecting plate 11 is connected to the first mounting plate 12, the first mounting plate 12 and the second mounting plate 13 are arranged in parallel, and the first mounting plate 12 and the second mounting plate 13 are connected through a plurality of elastic components; the first end face of the second mounting plate 13 is connected to an air pipe connector 15, and the second end face of the second mounting plate 13 is connected to a plurality of nozzle connectors 14, a negative pressure chamber is provided in the second mounting plate 13, and the air pipe connector 15 and the nozzle connector 14 are both connected to the negative pressure chamber. The air pipe joint 15 is connected to the vacuum pump to evacuate the negative pressure chamber of the second mounting plate 13, so that the end of the suction nozzle joint 14 has suction, so that the horizontally placed insulating rubber pad can be sucked up; by setting a plurality of suction nozzle joints 14, a plurality of insulating rubber pads can be adsorbed and sucked up at one time, so that a plurality of insulating rubber pads can be glued to the battery cell at the same time, thereby improving work efficiency; wherein, the elastic component is used for floating contact with the battery cell when the gripper component fits the insulating rubber pad 16 to the battery cell, so that a certain pressure is maintained between the insulating rubber pad and the battery cell, so that the attachment is firm, and at the same time, the driving arm that drives the mounting bracket to move is prevented from being subjected to excessive bending moment, thereby improving the service life.

[0034] In some embodiments, a plurality of suction nozzle connectors 14 are divided into a plurality of adsorption groups, each adsorption group includes at least two suction nozzle connectors 14, and each adsorption group is used to adsorb an insulating rubber pad 16, thereby ensuring that each insulating rubber pad 16 is adsorbed by at least two suction nozzle connectors 14, so that the adsorption range is larger and the adsorption effect is stable.

[0035] Preferably, a check valve is provided in each suction nozzle joint 14 to prevent the vacuum of all suction nozzle joints 14 from being broken due to air leakage in one suction nozzle joint 14, thereby improving safety.

[0036] In some embodiments, each adsorption group is connected to a protection block 17, and the protection block 17 is fixed to the second mounting plate 13 by bolts. Each protection block 17 is provided with a plurality of through holes corresponding to the suction nozzle joint 14, and the suction nozzle joint 14 passes through the through holes. The protection block 17 is used to protect the suction nozzle joint 14, and is waterproof and dustproof. The through holes are used to position the suction nozzle joint 14, so that the suction nozzle joint 14 is installed more firmly.

[0037] In some embodiments, the elastic component includes a positioning guide sleeve 18, a guide rod 19 and a spring. The positioning guide sleeve 18 passes through the first mounting plate 12 and is fixedly connected to the first mounting plate 12. The first end of the guide rod 19 passes through the positioning guide sleeve 18 and is connected to a baffle 20. The second end of the guide rod 19 is fixedly connected to a second connecting plate 21. The second connecting plate 21 is fixed to the second mounting plate 13 by bolts. A spring is sleeved on the outer side of the guide rod 19. One end of the spring abuts against the first mounting plate 12, and the other end of the spring abuts against the second connecting plate 21. When the insulating rubber pad contacts the battery cell, the second connecting plate 21 stops moving due to the supporting force, the first mounting plate 12 can continue to move forward guided by the guide rod 19, and the spring can be compressed under force, thereby avoiding the driving arm from being directly subjected to rigid resistance, reducing bending moment, and improving service life.

[0038] In some embodiments, the first mounting plate 12 is connected to a first position detection device 22, and the second mounting plate 13 is connected to a first stroke detection plate 23. When the first stroke detection plate 23 moves to a predetermined position, the first position detection device 22 outputs an electrical signal to quantitatively control the glue laminating pressure to ensure more stable glue laminating quality.

[0039] Preferably, the first position detection device 22 is a through-beam sensor, which is installed at a predetermined position between the first mounting plate 12 and the second mounting plate 13 through a bracket. When the first mounting plate 12 and the second mounting plate 13 are displaced toward each other and the first stroke detection plate 23 blocks the light reception of the through-beam sensor, it means that the pressure of the glue is in place and the forward displacement can be stopped, thereby quantitatively controlling the glue pressure and ensuring a more stable glue quality.

[0040] In some embodiments, a second position detection device 24 is provided on the outer wall of the second side plate 2, the shaft rod 5 passes through the second side plate 2, and is connected to a second stroke detection plate 25, the second stroke detection plate 25 is parallel to the second side plate 2, when the second stroke detection plate 25 moves to a predetermined position, the second position detection device 24 outputs an electrical signal to ensure precise control of the position of the gripper assembly.

[0041] Preferably, the second position detection device 24 includes a first proximity switch and a second proximity switch. By adjusting the positions of the two proximity switches, when the flip bracket 4 drives the gripper assembly to move to a horizontal state, the first proximity switch is triggered to stop the flip driving mechanism. When the flip bracket 4 drives the gripper assembly to move to a vertical state, the second proximity switch is triggered to stop the flip driving mechanism, thereby ensuring precise control of the position of the gripper assembly.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
