In the embodiment of the application, the datum line 11 is arranged on the battery shell 1, and the setting position of the leading-out terminal 3 is determined by controlling the angle between the tab 21 and the datum line 11 and the angle between the leading-out terminal 3 and the datum line 11, so that the angle formed between the tab 21 and the leading-out terminal 3 finally meets the setting requirement.
Specifically, the battery includes a battery case 1, and the battery case 1 may be a battery cover or a battery cup. The battery cell 2 includes a first tab and a second tab. For example, one end of the first tab is electrically connected to the battery cell 2, the other end of the first tab is electrically connected to the inner surface of the battery cover, and the first tab is clamped between the end of the battery cell 2 and the inner surface of the battery cover in a flat structure. One end of the second tab is electrically connected with the battery core 2, the other end of the second tab is connected with the inner surface of the battery cup, and the second tab is in a flat structure and is clamped between the end part of the battery core 2 and the inner surface of the battery cup.
A terminal 3 is provided on the outer surface of the battery case 1. In the application of the battery to the electronic equipment, the leading-out terminal 3 on the battery is electrically connected with the electronic equipment so as to realize the electrical connection between the battery and the electronic equipment. For example, a first lead-out terminal is provided on the outer surface of the end portion of the battery cover, and the first lead-out terminal serves as a lead-out terminal of the first tab. In a specific embodiment, in the case that the first tab is a positive tab, the first lead-out terminal serves as a lead-out terminal of the positive electrode. For example, a second lead-out terminal is provided on the outer surface of the end of the battery cup, and the second lead-out terminal serves as a lead-out terminal for the second tab. In a specific embodiment, in the case that the second tab is a negative tab, the second lead-out terminal is used as a lead-out terminal of the negative electrode.
In this embodiment, the tab 21 has a first center line 211, wherein the first center line 211 extends in a length direction of the tab 21. For example, the tab 21 has an elongated structure, and the elongated structure has a first short side and a second short side which are oppositely arranged, wherein a line connecting the center of the first short side and the center of the second short side is a first center line 211 of the tab 21.
In this embodiment, the lead-out terminals 3 are generally arranged in the circumferential direction of the battery case 1. The terminal 3 is embodied with a second centre line 31. Wherein the second center line 31 extends in the radial direction of the battery case 1 when the terminal 3 is disposed on the battery case 1. In a specific embodiment, the terminal 3 is a metal sheet structure, for example, the metal sheet structure is a strip structure, and the second center line 31 of the terminal 3 is a connection line of centers of two short sides of the metal sheet that are oppositely disposed. In another embodiment, the terminal 3 is a metal wire structure, for example, the metal wire is a long strip line structure, and the second center line 31 of the terminal 3 is the metal wire.
In this embodiment, the battery case 1 has a reference line 11 thereon. Wherein the reference line 11 may be a line engraved on the outer surface of the battery case 1 passing through the center of the battery case 1; alternatively, the mark 10 is formed on the outer surface of the battery case 1, and a line connecting the center of the mark 10 and the battery case 1 is regarded as the reference line 11.
The reference line 11 is formed on the outer surface of the battery housing 1, for example using laser marking or any other surface marking process not limited to laser marking processes. For example, a reference line 11 is formed on the outer surface of the end of the cell cover, or a reference line 11 is formed on the outer surface of the end of the cell cup.
Referring to fig. 1 to 3, in step S101, it is first necessary to set the angle between the first center line 211 and the second center line 31 to a predetermined angle a. Wherein an angle formed between the tab 21 and the lead-out terminal 3 is defined as an angle between the first center line 211 and the second center line 31. The predetermined angle a is an angle meeting the user setting requirements, that is, the predetermined angle a is an angle that needs to be set in advance. For example, a predetermined angle a set in advance may be output to the display panel.
In step S102, the battery case 1 is rotated in the first direction such that the angle between the reference line 11 and the first coordinate axis is the first angle a1 in accordance with the requirement of the set predetermined angle.
Specifically, the battery case 1 is disposed on the turntable, and the turntable is driven by the driving portion to drive the battery case 1 disposed on the turntable to rotate. For example, the battery case 1 may be rotated clockwise, or the battery case 1 may be rotated counterclockwise.
The driving part may be, for example, a motor that drives the battery case 1 to rotate so that an angle between the reference line 11 provided on the battery case 1 and the first coordinate axis is a first angle a 1.
Wherein the first coordinate axis is a fixed coordinate axis. For example, the first coordinate axis is a one-dimensional coordinate axis. The first coordinate axis is a coordinate axis pointing in the north direction in this embodiment.
In one embodiment, the first angle a1 may be any angle (i.e., the battery case 1 rotates randomly), and the first angle a1 is acquired by the sensor in real time and is input into the display panel a 1. After the first angle a1 is output to the display panel, the algorithm in the display panel can compare the magnitude relationship of the first angle a1 and the predetermined angle a.
In one embodiment, or the predetermined angle is entered into the display panel, an algorithm in the display panel divides the predetermined angle A into a plurality of combinations of summation modes. For example, in one embodiment, the predetermined angle a is 90 °, the controller divides the predetermined angle a into 90 ° +0 °; 60 ° +30 °; 30 ° +60 °; 45 ° +45 °; 37 ° +53 °; 100 ° + (-10 °); 130 deg. + (-40 deg.), when the user selects one of the combination, the first angle a1 is determined, and the determined first angle a1 is transmitted to the controller, which controls the rotating motor to rotate, and the rotating motor rotates the battery housing 1, so that the angle between the reference line 11 and the first coordinate axis is the determined first angle a 1. Since the user selects one combination among the plurality of combinations, the relationship between the first angle a1 and the predetermined angle a is determined.
In the present embodiment, after the battery case 1 is rotated in the first direction so that the angle between the reference line 11 and the first coordinate axis is the first angle a1, the battery case 1 needs to be positioned. For example, the battery case 1 is fastened in this position, the battery case 1 is in this position, and the angle between the reference line 11 on the battery case 1 and the first coordinate axis is the first angle a 1.
S103, positioning and installing the battery cell 2 to enable a first central line 211 of the tab 21 to be arranged corresponding to a first coordinate axis;
specifically, the electric core 2 is positioned through the positioning tray, and after the electric core 2 is positioned, the first central line 211 of the tab 21 on the electric core 2 is set corresponding to the first coordinate axis. Specifically, the first center line 211 of the tab 21 is arranged in parallel with the first coordinate axis. After the positioning of the battery cell 2 is completed, the positioned battery cell 2 is installed in the battery shell 1. The battery cell 2 is mounted in the battery case 1, and the first center line 211 of the tab 21 on the battery cell 2 is also parallel to the first coordinate axis.
Since the first center line 211 of the tab 21 is arranged in parallel with the first coordinate axis, the angle between the first center line 211 of the tab 21 and the reference line 11 is also the first angle a 1.
In step S104, the positioned battery cell 2 is placed in the positioned battery case 1, and the angle between the first center line 211 of the tab 21 in the battery case 1 and the reference line 11 is determined as the first angle a1, and the setting position of the lead-out terminal 3 is determined according to the relationship between the first angle a1 and the predetermined angle a.
Specifically, the position of the lead-out terminal 3 is determined based on the relationship between the first angle a1 and the predetermined angle a. For example, there is a difference between the first angle a1 and a predetermined angle a, where the difference is defined as a second angle a2, and the lead-out 3 is set according to the magnitude relationship of the second angle a 2. Wherein the second angle a2 is the angle formed between the pigtail 3 and the reference line 11.
After the position of the lead-out terminal 3 is determined by the second angle a2, the angle of the tab 21 to the lead-out terminal 3 at this time is a predetermined angle formed between the first center line 211 of the tab 21 and the second center line 31 of the lead-out terminal 3. That is, the angle formed between the tab 21 and the lead-out terminal 3 is an angle meeting the set requirement.
In the embodiment of the application, the reference line 11 is arranged on the battery shell 1, and the angle between the tab 21 and the reference line 11 and the angle between the lead-out terminal 3 and the reference line 11 are indirectly controlled to further determine the setting position of the lead-out terminal 3, so that the angle formed between the tab 21 and the lead-out terminal 3 finally meets the setting requirement. The angle that forms between utmost point ear 21 and the leading-out end 3 accords with the settlement requirement to can effectual management and control eliminate even: the effect of the battery magnetic field on the performance of the antenna of the electronic device, the noise generated by the battery magnetic field in the acoustic element, and the effect on the performance of all components sensitive to the battery magnetic field.
In one embodiment, the lead-out terminal 3 has a second center line 31 extending in the radial direction of the battery case 1; the difference between the first angle a1 and the predetermined angle a is a second angle a2, wherein the second angle a2 is the angle between the second centerline 31 and the reference line 11.
Specifically, the position of the lead-out terminal 3 is determined by the second angle a2, and the angle of the tab 21 with the lead-out terminal 3 is a predetermined angle formed between the first center line 211 of the tab 21 and the second center line 31 of the lead-out terminal 3. That is, the angle formed between the tab 21 and the lead-out terminal 3 is an angle meeting the set requirement.
In one embodiment, the second center line 31 of the lead-out terminal 3 overlaps or is parallel to the reference line 11 in a case where the first angle is equal to the predetermined angle.
In this embodiment, the first angle a1 is equal to the predetermined angle a, i.e. the difference between the first angle a and the predetermined angle a is 0 ° and the second angle a2 is 0 °, i.e. the angle between the second centre line 31 and the reference line 11 is 0 °. The reference line 11 is located at the welding position of the terminal 3, i.e. the second central line 31 of the terminal 3 is overlapped with the reference line 11. Alternatively, the terminal 3 is welded to the battery case 1, and the second center line 31 of the terminal 3 is arranged parallel to the reference line 11.
In one embodiment, referring to fig. 2-3, in the case where the first angle is less than the predetermined angle, the terminal 3 is disposed away from the first coordinate axis relative to the reference line 11, and the second centerline 31 of the terminal 3 forms a second angle with the reference line 11, wherein the second angle is the predetermined angle minus the first angle.
In this embodiment, the first angle a1 is smaller than the predetermined angle a, that is, the included angle formed between the first center line 211 of the tab 21 and the reference line 11 is not sufficient to satisfy the predetermined angle a. In the case where the first angle a1 is less than the predetermined angle a, the difference of the predetermined angle a minus the first angle a1 is a positive number. That is, the second angle a2 obtained by subtracting the first angle a1 from the predetermined angle is a positive number. The first center line 211 of the tab 21 and the second center line 31 of the lead-out terminal 3 should be located at both sides of the reference line 11, respectively, and the second center line 31 of the lead-out terminal 3 forms a second angle a2 with the reference line 11, when the first angle a1 plus the second angle a2 is equal to the predetermined angle a. The sum of the first angle a1 formed between the first center line 211 of the tab 21 and the reference line 11 and the second angle a2 formed between the second center line 31 of the lead-out terminal 3 and the reference line 11 at this time is the predetermined angle a.
The angle between the tab 21 and the reference line 11 and the angle between the lead-out end 3 and the reference line 11 are indirectly controlled, so that the setting position of the lead-out end 3 is determined, and finally the angle formed between the tab 21 and the lead-out end 3 meets the setting requirement.
In one embodiment, referring to fig. 4, in case the first angle a1 is greater than the predetermined angle a, the lead-out terminal 3 is disposed closer to the first coordinate axis with respect to the reference line 11, and the second centerline 31 of the lead-out terminal 3 forms an angle with the reference line 11 as a second angle a2, wherein the second angle a2 is the first angle a1 minus the predetermined angle a.
In this embodiment, the first angle a1 is greater than the predetermined angle a, i.e., the included angle formed between the first center line 211 of the tab 21 and the reference line 11 exceeds the predetermined angle a. In the case where the first angle a1 is greater than the predetermined angle a, the difference of the predetermined angle a minus the first angle a1 is negative. I.e. the second angle a2, which is the predetermined angle a minus the first angle a1, is negative. The first center line 211 of the tab 21 and the second center line 31 of the lead-out terminal 3 should be located on the same side of the reference line 11 at this time, and the second center line 31 of the lead-out terminal 3 and the reference line 11 form a second angle a2 therebetween, when the first angle a1 minus the second angle a2 is equal to the predetermined angle a.
The difference between the first angle a1 formed between the first center line 211 of the tab 21 and the reference line 11 and the second angle a2 formed between the second center line 31 of the lead-out terminal 3 and the reference line 11 at this time is the predetermined angle a.
The angle between the tab 21 and the reference line 11 and the angle between the lead-out end 3 and the reference line 11 are indirectly controlled, so that the setting position of the lead-out end 3 is determined, and finally the angle formed between the tab 21 and the lead-out end 3 meets the setting requirement.
In one embodiment, a first angle sensor is included that captures a first angle a1 between the reference line 11 and the first coordinate axis in real time.
In this embodiment, the angle between the reference line 11 provided on the battery case 1 and the first coordinate axis is changed in real time while rotating the battery case 1, and the first angle a1 between the reference line 11 and the first coordinate axis is acquired in real time by the first angle sensor. When the battery case 1 stops rotating, the first angle sensor can transmit the determined first angle to the display panel and perform display.
Or the image is transmitted to the image sensor in a real-time photographing mode, and the image sensor acquires the position of the reference line 11, so that the first angle between the first coordinate axis and the reference line 11 is calculated in real time. When the rotation of the battery case 1 is stopped, the last angle value calculated is used as the first angle a1 between the determined first coordinate axis and the reference line 11.
In one embodiment, a second angle sensor is included which captures the angle between the second centerline 31 and the reference line 11 in real time.
In this embodiment, the positioned battery cell 2 is placed in the battery casing 1, the battery cell 2 is placed in the battery casing 1, and the first center line 211 of the tab 21 on the battery cell 2 is arranged corresponding to the first coordinate axis, so that the angle between the first center line 211 of the tab 21 and the reference line 11 is the first angle a 1. After the angle between the first center line 211 of the tab 21 and the reference line 11 is determined, the lead terminal 3 is provided on the outer surface of the battery case 1. When the leading-out terminal 3 is arranged, the angle between the leading-out terminal 3 and the datum line 11 is acquired in real time through the second angle sensor. When the acquired angle between the second center line 31 of the terminal 3 and the reference line 11 satisfies the second angle a2, the terminal 3 is welded.
