In the field of electric automobiles, the degree of automation of the manufacture of power batteries, the core component of the electric automobiles, is also increasing. In the production process of the power battery, the working procedures are various, and the requirements on the integration level and the precision of equipment are higher and higher due to the small volume of the power battery.

The utility model discloses an utilize gravity from the moulding-die to organize rotatory rubber coating in coordination with the pole piece, maintain when realizing automatic rubber coating and last moulding-die, effectively guarantee the rubber coating quality.
In the prior art, the problem of the quality of the encapsulation is solved by utilizing the cooperation of gravity and the rotation of the encapsulation shaft as in the patent document with the authorization number of CN 215869519U. On one hand, the space arrangement of the equipment is limited by using the gravity; on the other hand, the device does not consider the problem of encapsulation width, and the integration level and the intelligent degree are not high. Meanwhile, in the prior art, a manual encapsulation mode is adopted, but the manual encapsulation mode is low in efficiency on one hand, and the encapsulation precision is difficult to guarantee on the other hand. In conclusion, when the prior art is used for encapsulating the battery core, the intelligent degree is not high, the requirements of different batteries on different encapsulation lengths and widths cannot be met, the encapsulation quality cannot be guaranteed, and the problems of folds and unevenness are easy to occur.
Disclosure of Invention
The invention provides a battery core encapsulation control method aiming at the technical problems that in the prior art, battery core encapsulation efficiency is low, intelligence degree is not high, and wrinkles or unevenness are easy to generate.
One of the ideas of the invention is that the invention eliminates the problems of easy generation of folds and unevenness of an adhesive tape in the process of encapsulating the battery cell by synchronizing the operation speeds of the adhesive pulling mechanism and the driving mechanism, thereby improving the encapsulation quality.
Specifically, the battery core encapsulation operation is to wrap a layer of adhesive tape on the end part of the battery core, so that unnecessary friction between the battery core and a battery shell in the case entering or battery transportation process is avoided. However, in the prior art, the driving mechanism is adopted to drive the battery core to rotate, and then the mode of completing the rubber coating operation has certain disadvantages. On one hand, the battery cell is easy to generate the problems of wrinkles and unevenness in a mode of rotating and winding the adhesive tape; on the other hand, the position of the tape is easy to shift during the rotation of the wrapping shaft, thereby affecting the width of the wrapping tape.
When the adhesive tape at the end part of the battery cell is wrinkled and uneven, the subsequent battery cell casing operation is influenced; when the adhesive tape deviates, the process requirement of the battery cell on the encapsulation width cannot be met. Because the sticky tape is not all around electric core tip, its one side is laminated with electric core and is accomplished the adhesion according to the technological requirement, and the opposite side exposes outside electric core tip. The horizontal edge of the adhesive tape exposed outside the end part of the battery cell has a preset distance with the horizontal edge of the end part of the battery cell, and the preset distance is the width exposed value of the adhesive tape. Different cells and different battery manufacturing processes have different requirements for this width.
Therefore, in order to avoid the problems of wrinkling, unevenness and deviation of the adhesive tape in the rubber coating process, the method adopts a mode of synchronous operation of the adhesive tape pulling mechanism and the driving mechanism to ensure that the adhesive tape continuously has tension in the rubber coating process. On one hand, the glue pulling shaft and the glue coating shaft have a horizontal distance, and the glue pulling shaft simultaneously feeds forwards in the winding process of the glue coating shaft; on the other hand, the length of the feeding of the rubber pulling shaft and the length of the rubber wrapping shaft for winding the rubber belt are synchronized by adopting a synchronizing device. Through the design, the adhesive tape can be ensured to be in a stretched state and have tension in the encapsulation process of the battery cell, so that the problems of wrinkles, unevenness and deviation of the adhesive tape in the encapsulation process are solved.
Further, another idea of the present invention is that the method performs the adjustment of the position of the adhesive tape by the positioning unit, so that the encapsulation device can meet the requirements of different encapsulation widths.
Specifically, the requirements for the width exposure value of the encapsulated adhesive tape are different for batteries of different types and different process requirements. In order to enable the extending width value of the adhesive tape relative to the end part of the battery cell to be the same as the preset exposed width value of the adhesive tape, the position of the adhesive tape is adjusted in the width direction of the adhesive tape through a first limiting wheel and a second limiting wheel of the positioning unit, and therefore the extending distance of the adhesive tape relative to the end part of the battery cell meets the process requirements.
In some embodiments, the adhesive tape with the corresponding length is obtained by presetting the length value of the adhesive tape, so that the requirements of different battery cells are met.
Specifically, the demand diverse of the cylinder electricity core of different diameters size to sticky tape length for the sticky tape length that the messenger draws and gets can cover cylinder electricity core tip a week, makes through predetermineeing sticky tape length value and draws the sticky tape that the gluey mechanism can acquire different length to satisfy the rubber coating demand of the cylinder electricity core of diameter size not.
In some embodiments, the present invention provides for adjusting the tension between the tapes with a predetermined tension.
Specifically, drive electric core is before the rotatory rubber coating of drive electric core, for the rate of tension that makes the sticky tape satisfies the in-service use demand, adjusts the rate of tension of sticky tape through the rate of tension to the sticky tape has certain zhang long when drawing gluey mechanism and drawing the sticky tape, and then improves the roughness of electric core rubber coating in-process.
In combination with the above concept, the present invention provides a method for controlling encapsulation of a battery cell, comprising:
the driving mechanism drives the battery cell to rotate, and the adhesive tape is wound on the end part of the battery cell through the rotation of the battery cell;
in the process that the battery core rotates to wind the adhesive tape on the end part of the battery core, the adhesive tape pulling mechanism moves towards the end part of the battery core in a mode of synchronous movement with the driving mechanism.
Based on the technical scheme, the driving mechanism drives the battery core to rotate and encapsulate the rubber, and the rubber pulling mechanism and the driving mechanism run synchronously. Because the adhesive tape is stretched by the adhesive pulling mechanism and the driving mechanism, the adhesive tape continuously has tension in the encapsulating process, so that the problem that a battery cell is not wrinkled or shifted in position in the encapsulating process is solved, the flatness of the adhesive tape in the encapsulating process of the battery cell is further improved, and the encapsulating quality of the adhesive tape is also improved.
Further, the method for controlling encapsulation of the battery core provided by the invention is characterized in that the adhesive pulling mechanism moves towards the end part of the battery core in a manner of synchronous movement with the driving mechanism, and specifically comprises the following steps:

Detailed Description
The present invention will be described in detail below with reference to the accompanying fig. 1 to 7.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The invention provides a method and a device for controlling battery core encapsulation, which have the advantages of high battery core encapsulation flatness, good quality and good adaptability to different process requirements.
As shown in fig. 1, when the cell is encapsulated, the driving mechanism drives the cell to rotate in step S10; in the rotation process of the battery cell, in step S20, the tape pulling mechanism moves towards the end of the battery cell in a manner of synchronous movement with the driving mechanism, so that the tape is continuously in a suitable tension state and cannot be too tight or too loose; finally, the cell winds the adhesive tape around its end by rotating according to step S30. In the encapsulation process of the battery core, the adhesive tape is continuously in a proper tension state, so that the flatness of the adhesive tape is better, namely the encapsulation quality is higher. The synchronous motion means that the horizontal speed of the adhesive tape conveyed by the adhesive tape pulling mechanism is the same as the linear speed of the driving mechanism driving the battery core to rotate and wind the adhesive tape.
It is worth to be noted that one end of the adhesive tape is fixed on the adhesive tape pulling mechanism, the other end of the adhesive tape is fixed at the end part of the battery cell, and the battery cell is driven by the driving mechanism to rotate. The driving mechanism drives the battery core to rotate and encapsulate the rubber belt, the rubber belt is synchronously conveyed to the end part of the battery core by the rubber belt pulling mechanism when the battery core winds the rubber belt through the other end of the rubber belt, namely the speed of winding the rubber belt by the battery core is equivalent to the speed of conveying the rubber belt by the rubber belt pulling mechanism, and therefore the rubber belt is continuously in a tension state in the encapsulation process.
Further, a synchronous proportion value of the glue pulling mechanism and the driving mechanism is obtained through a preset diameter and linear speed of the battery cell, and the control unit controls the glue pulling mechanism and the driving mechanism to synchronously operate according to the synchronous proportion value.
Specifically, a set of high-precision synchronous control unit is arranged between the driving unit of the glue pulling mechanism and the driving unit of the glue coating mechanism, and the high-precision synchronous control device controls the driving unit of the glue pulling mechanism and the driving unit of the glue coating mechanism to synchronously operate so as to realize the synchronous motion of the driving unit and the driving unit. The high-precision synchronous control unit controls a driving unit of the glue drawing mechanism and a driving unit constructed by the driving mechanism to synchronously run according to the calculated synchronous proportion value, so that the linear speed of the driving mechanism for driving the battery core to encapsulate the glue is equivalent to the linear speed of the glue drawing mechanism for driving the tape to feed, and the tape is continuously in a proper tension state in the process of encapsulating the battery core.
Furthermore, according to different process requirements, the widths of the adhesive tapes extending outwards relative to the ends of the battery cells in the encapsulation process of the battery cells are different. As shown in fig. 2, before the battery cell is rotationally encapsulated, a tape exposure width value is preset according to step S01, and a tape outward-extending width of the tape relative to the battery cell end portion is adjusted according to the preset tape exposure width value, so as to meet the requirements of different outward-extending widths of the tape relative to the battery cell end portion, that is, meet the process requirements of different tape exposure widths.
Furthermore, be provided with the positioning unit on the rate of tension mechanism, including the spacing wheel of first spacing wheel and second on the positioning unit, through the steerable sticky tape of the removal of the spacing wheel of first spacing wheel and second moves on sticky tape width direction to realize the regulation of the relative electric core tip of sticky tape outwards stretched out width.
In some embodiments, the lengths of the tapes required for the cylindrical battery cells with different diameters are different, so that the length value of the tape is preset in step S02, and the clamping unit of the tape pulling mechanism obtains the tapes with corresponding lengths according to the preset length value of the tape, so as to meet the encapsulation requirements of the cylindrical battery cells with different diameters and improve the flexibility of encapsulation equipment.
Specifically, the circumference of the end of the cylindrical battery cell is obtained according to the diameter of the cylindrical battery cell, and the circumference is the required length value of the adhesive tape. It should be noted that, in actual production, the length of the preset adhesive tape should be slightly greater than the required length of the adhesive tape, so as to meet the requirement of encapsulating the end of the battery cell by 360 degrees.
In some embodiments, to ensure that the tension of the adhesive tape obtained by the adhesive tape pulling mechanism satisfies the adhesive demand, as shown in fig. 2, the tension degree of the adhesive tape is preset through step S03, and the tension degree mechanism adjusts the tension of the adhesive tape according to the preset tension degree of the adhesive tape, so that the tension state of the adhesive tape is not too tight or too loose, and the flatness of the encapsulation is improved.
Preferably, the tightness mechanism adopts weights to complete the tension adjustment of the adhesive tape.
After the tension of the adhesive tape is adjusted, the adhesive tape pulling mechanism clamps one end of the adhesive tape through the clamping unit of the adhesive tape pulling mechanism.
In some embodiments, after the width of the adhesive tape extending outward from the end of the cell is adjusted, as shown in fig. 2, the adhesive tape is pressed on the cell by the pressing mechanism according to step S04, and the cutting mechanism moves to a direction close to the adhesive tape along with the pressing mechanism, so as to complete the cutting operation of the adhesive tape.
Specifically, the pressing mechanism is arranged between the end of the battery cell and the positioning unit, after the positioning unit finishes the operation of adjusting the width of the adhesive tape, the pressing mechanism presses the adhesive tape on the battery cell, then the shearing mechanism moves towards the direction of the adhesive tape along with the pressing mechanism, and the operation of shearing the adhesive tape is finished, so that the pulled adhesive tape on the adhesive tape pulling mechanism is separated from the adhesive tape on the adhesive tape disc.
Example 2
As shown in fig. 3, the control device for encapsulating a battery cell provided by the present invention includes a driving mechanism 10, a rubber pulling mechanism 20, and a control unit 30, where the control unit 30 obtains a synchronous ratio value between a driving unit of the rubber pulling mechanism and a driving unit of the driving mechanism according to a diameter of the battery cell and a linear velocity of rotation of the battery cell, and makes the rubber pulling mechanism 10 move towards an end of the battery cell in a manner of moving synchronously with the driving mechanism according to the synchronous ratio value.
Preferably, the drive units of the glue pulling mechanism and the drive mechanism are high-precision servo motors. And a synchronous control device is arranged in the control unit 30, and is connected with the two sets of high-precision servo motors and used for acquiring the synchronous proportion value and controlling the two sets of high-precision servo motors to operate according to the synchronous proportion value, so that the glue drawing mechanism moves towards the end part of the battery cell in a manner of synchronous operation with the driving mechanism.
It should be noted that fig. 4 is an enlarged view of a portion a in fig. 3 to facilitate understanding of the positional relationship of the components in fig. 3.

In the winding process of the adhesive tape 50, along with the rotation of the battery cell 40, the clamping unit 21 of the adhesive pulling mechanism 20 synchronously moves horizontally towards the end of the battery cell, so that the adhesive tape 50 is continuously kept in a proper tension state, and the problem of wrinkling or unevenness of the adhesive tape 50 in the winding process is avoided, that is, the encapsulation quality of the battery cell is improved.
Preferably, the tensioning mechanism 60 adjusts the tension of the adhesive tape by a weight, wherein the tensioning mechanism 60 is arranged on both sides of the mounting plate of the encapsulation device, as shown in fig. 3 and 5.
Preferably, the pressing mechanism 70 and the shearing mechanism 80 are disposed on one side of the battery cell close to the positioning unit 22, and the clamping unit 21 of the glue pulling mechanism is disposed on one side of the battery cell far from the positioning unit 22.
