Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a bubble fixing device. Background Technology

[0002] In the post-filling process of battery cells, some manufacturers have added a process of adding air bubbles into the filling port of the battery cell before welding. This makes it easier to perform airtightness testing on the welding position of the sealing nail after the sealing nail is welded at the filling port.

[0003] In related technologies, during the airtightness test of the sealing nail welding position, the bubble is usually a round and flat structure with only a small protrusion in the middle. It is necessary to ensure that the protrusion of the bubble fits the lower surface of the sealing nail to facilitate the subsequent laser melting of the bubble. However, after the bubble is placed at the injection port, the bubble is prone to shaking during the transfer of the battery cell to the next process, which can cause the bubble to shift in position and affect the fit between the protrusion of the bubble and the sealing nail.

[0024] In related technologies, during the airtightness test of the sealing nail welding position, the bubble is typically a round, flat structure with only a slight protrusion in the center. It is necessary to ensure that the protruding part of the bubble fits against the lower surface of the sealing nail to facilitate the subsequent laser melting of the bubble. However, after the bubble is placed in the injection port, the bubble is prone to vibration during the transfer of the battery cell to the next process, causing the bubble's position to shift and affecting the fit between the protruding part of the bubble and the sealing nail. To address these issues, this application provides a bubble fixing device that can more firmly fix the bubble in the injection port of the battery cell, preventing relative displacement between the bubble and the battery cell during transfer.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 and Figure 2 The bubble fixing device includes a dispensing machine 1, a conveyor line, a bubble generator 3, and a handling arm 4. The dispensing machine 1 includes a bracket 11 and a dispensing head 12. The dispensing head 12 is mounted on the bracket 11 and can dispense adhesive to the liquid injection port of the battery cell.

[0027] See Figure 1 and Figure 2The conveyor line is located on one side of the dispensing machine 1. The conveyor line includes a jig 2 and a first drive mechanism. The jig 2 carries multiple battery cells simultaneously. The first drive mechanism is connected to the jig 2 and can drive the jig 2 to move below the dispensing head 12, with the battery cell's injection port positioned below the dispensing head 12. The first drive mechanism can also drive the jig 2 away from the dispensing head 12. A bubble maker 3 is located on one side of the dispensing machine 1 and is used to output bubbles. The bubble surface is a thin film filled with an inert gas, which can be helium. A transporter 4 is located on one side of the bubble maker 3 and can transfer the bubbles from the bubble maker 3 to the battery cells on the jig 2. In actual operation, the first drive mechanism first transports the jig 2 to the dispensing head 12, the dispensing head 12 injects the molten adhesive into the injection port, the first drive mechanism then moves the jig 2 to the next station, the transporter 4 transfers the bubbles on the bubble maker 3 to the injection port, and places the bubbles on the molten adhesive, so that the adhesive and the bubbles adhere together. After the adhesive solidifies into a block, the block and the bubbles are fixed together.

[0028] This application uses a dispensing head 12 to dispense adhesive into the cell's liquid injection port, using the adhesive to fix the air bubbles and ensure that the position of the air bubbles does not shift during the cell's transport. At the same time, the adhesive reduces the space inside the liquid injection port, ensuring that the point where the air bubble is to melt and burst is tightly attached to the lower surface of the sealing nail, improving the stability of the air bubble position during subsequent cell liquid injection port sealing inspection, and ensuring that the air bubble can melt and burst after laser irradiation.

[0029] See Figure 1 and Figure 2 The dispensing machine 1 also includes a first detection camera 13, which is mounted on the bracket 11. The first detection camera 13 is used to photograph the battery cell, and the first detection camera 13 can be a CCD camera. The first detection camera 13 can send the captured image data to the control terminal, and the control terminal confirms the position of the battery cell based on the image data captured by the first detection camera 13. The dispensing head 12 dispenses glue to the battery cell according to the position of the battery cell detected by the first detection camera 13, ensuring that the dispensing head 12 can accurately dispense glue onto the liquid injection port of the battery cell. In actual operation, the first drive mechanism first transports the jig 2 to the dispensing head 12, the first detection camera 13 photographs the battery cell, and the control terminal adjusts the position of the dispensing head 12 according to the captured image data so that the dispensing head 12 is directly facing the liquid injection port of the battery cell on the jig 2, or the first drive mechanism controls the jig 2 to move so that the dispensing head 12 is directly facing the liquid injection port of the battery cell on the jig 2; the dispensing head 12 then injects the molten glue into the liquid injection port.

[0030] See Figure 1-3The transporter 4 includes a second driving mechanism and a first adsorption mechanism 41. The second driving mechanism is connected to the first adsorption mechanism 41, and drives the first adsorption mechanism 41 to move between the bubble maker 3 and the fixture 2. The first adsorption mechanism 41 is used to adsorb or release bubbles. In some embodiments, the first adsorption mechanism 41 is a vacuum suction cup. After contacting a bubble, the first adsorption mechanism 41 lifts the bubble by negative pressure. After the second driving mechanism moves the first adsorption mechanism 41 above the liquid injection port of the battery cell, the first adsorption mechanism 41 releases the bubble, and the bubble falls into the liquid injection port. By adsorbing or releasing bubbles through the adsorption mechanism, it is ensured that the bubbles can be transferred to the liquid injection port of the battery cell more smoothly, and the bubbles will not be punctured by the transporter 4.

[0031] See Figure 1-3 The transporter 4 also includes a first guide rail 42, and a second drive mechanism including a translation module 43 and a lifting module 44. The first guide rail 42 extends along a first direction, and the lifting module 44 is mounted on the first guide rail 42. The translation module 43 drives the lifting module 44 to slide along the first guide rail 42. A first adsorption mechanism 41 is mounted on the lifting module 44, and the lifting module 44 drives the first adsorption mechanism 41 to rise and fall. The translation module 43 can be a lead screw slide module, a hydraulic cylinder, or a pneumatic cylinder, and the lifting module 44 can be a lead screw slide module, a hydraulic cylinder, or a pneumatic cylinder. In actual operation, the translation module 43 drives the lifting module 44 to move to the foaming machine 3, positioning the first adsorption mechanism 41 above the bubble to be absorbed. The lifting module 44 then drives the first adsorption mechanism 41 to descend, bringing it into contact with the bubble. The first adsorption mechanism 41 adsorbs the bubble. The lifting module 44 then drives the first adsorption mechanism 41 to rise. The translation module 43 then drives the lifting module 44 to move to the fixture 2. The lifting module 44 then drives the first adsorption mechanism 41 to descend, bringing the bubble close to the injection port and into it. The first adsorption mechanism 41 releases the bubble, which then adheres to the adhesive. By having the translation module 43 drive the lifting module 44 to slide along the first guide rail 42, and by having the lifting module 44 drive the first adsorption mechanism 41 to rise and fall, the process of transferring the bubble from the foaming machine 3 to the battery cell's injection port becomes more precise, achieving automated operation of the handling arm 4.

[0032] See Figure 1-3The foam maker 3 is equipped with a discharge rack 31, which moves along a second direction. The discharge rack 31 is used to extend or retract from the foam maker 3. The discharge rack 31 has multiple discharge positions 311, each of which can hold one bubble. After the foam maker 3 produces a bubble, it uses the discharge rack 31 to transport the bubble out of the foam maker 3, facilitating the adsorption of the bubble by the first adsorption mechanism 41. The foam maker 3 is also equipped with a second adsorption mechanism located at the discharge position 311. The second adsorption mechanism is used to adsorb or release bubbles. During the process of the discharge rack 31 transporting the bubble out of the foam maker 3, the second adsorption mechanism adsorbs the bubble. After the first adsorption mechanism 41 adsorbs the bubble, the second adsorption mechanism releases the bubble. The second adsorption mechanism can be a vacuum suction cup. By adsorbing the bubble through the second adsorption mechanism, the bubble is prevented from falling off the discharge rack 31 during the process of transporting the bubble out of the foam maker 3.

[0033] See Figure 1-3 The handling arm 4 also includes a second detection camera 45, which may be a CCD camera. The second detection camera 45 is connected to the second drive mechanism and is used to photograph bubbles or battery cells. The second detection camera 45 can send the captured image data to the control terminal, which confirms the position of the bubble or battery cell based on the image data captured by the second detection camera 45. The first adsorption mechanism 41 grabs the bubble based on the bubble position detected by the second detection camera 45, or places the bubble based on the battery cell position detected by the second detection camera 45. When the first adsorption mechanism 41 needs to adsorb a bubble, the second detection camera 45 photographs the bubble, the discharge rack 31 then adjusts the position of the bubble by its own extension and retraction, and the lifting module 44 and the translation module 43 further adjust the position of the first adsorption mechanism 41 so that the first adsorption mechanism 41 can align with the bubble and adsorb it. When the first adsorption mechanism 41 needs to place the bubble at the liquid injection port of the battery cell, the second detection camera 45 takes a picture of the battery cell, and the lifting module 44 and the translation module 43 adjust the position of the first adsorption mechanism 41 so that the first adsorption mechanism 41 can be aligned with the liquid injection port of the battery cell and release the bubble, thereby ensuring the accuracy of the process of transferring the bubble from the bubble maker 3 to the liquid injection port of the battery cell.

[0034] See Figure 1 and Figure 2 The conveyor line includes a second guide rail extending in a second direction. A fixture 2 is mounted on the second guide rail, and a first drive mechanism drives the fixture 2 to slide along the second guide rail. The second guide rail defines the movement path of the fixture 2, ensuring that all fixtures 2 accurately reach the dispensing machine 1. The first drive mechanism can be a lead screw slide module, a pneumatic cylinder, or a hydraulic cylinder. Multiple fixtures 2 can exist simultaneously on the second guide rail. When multiple air bubbles are placed on all the battery cell injection ports on one fixture 2, another fixture 2 can reach the dispensing machine 1, where the dispensing head 12 dispenses adhesive into the battery cell, thereby improving the battery cell processing efficiency.

[0035] See Figure 1 and Figure 2 The second direction is perpendicular to the first direction, where the first direction is the X-axis and the second direction is the Y-axis. By moving the jig 2 along the second direction, the translation module 43 moves along the first direction, avoiding interference between the handling hand 4 and the jig 2, and also making the overall structure of the bubble fixing device more compact.

[0036] See Figure 1 and Figure 2 In some embodiments, the bracket 11 is provided with a third drive mechanism 111 and a third guide rail 112. The third guide rail 112 extends along a first direction, and a first detection camera 13 is mounted on the third guide rail 112. The third drive mechanism 111 is connected to the first detection camera 13, and the third drive mechanism 111 drives the first detection camera 13 to move along the third guide rail 112. The third drive mechanism 111 can be a lead screw slide module, a cylinder, or a hydraulic cylinder. By adjusting the position of the first detection camera 13 relative to the battery cell through the third drive mechanism 111, the first detection camera 13 can capture images of the battery cell from multiple angles, thereby facilitating more accurate calculation of the position of the battery cell's injection port by the control terminal.

[0037] See Figure 1 and Figure 2 In some embodiments, the bracket 11 is provided with a fourth drive mechanism 113 and a fourth guide rail 114. The fourth guide rail 114 extends along a second direction, and the dispensing head 12 is mounted on the fourth guide rail 114. The fourth drive mechanism 113 is connected to the dispensing head 12, and the fourth drive mechanism 113 drives the dispensing head 12 to move along the fourth guide rail 114. The fourth drive mechanism 113 can be a lead screw slide module, a cylinder, or a hydraulic cylinder. After the first drive mechanism transports the jig 2 to the dispensing head 12, the first detection camera 13 takes a picture of the battery cell. The control terminal sends a command to the fourth drive mechanism 113 based on the captured image data, and the fourth drive mechanism 113 adjusts the position of the dispensing head 12 so that the dispensing head 12 is aligned with the liquid injection port of the battery cell on the jig 2. Multiple battery cells can be placed at intervals along the second direction on the jig 2. The dispensing head 12 is driven by the fourth driving mechanism 113 to move along the fourth guide rail 114, so that the dispensing head 12 can apply glue to different battery cells on the same jig 2, thereby improving the processing efficiency of the battery cells.
