DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 10 As shown, the process and steps of a lithium battery processing method are described in detail below;

[0033] A lithium battery processing method, the method comprising the following steps:

[0034] Step 1: Slide the two assembly frames 1 together and fix the compression spring I between the two assembly frames 1;

[0035] Step 2: Fix and connect the conductive plate I2 and the conductive plate II3 on ​​the inner sides of the two assembly frames 1;

[0036] Step 3: Place multiple batteries 4 between the two assembly racks 1, with the positive electrodes of the multiple batteries 4 in contact with the conductive plate I2, and the negative electrodes of the multiple batteries 4 in contact with the conductive plate II3;

[0037] When in use, the two combined frames 1 can be used to limit the position of the multiple batteries 4 to ensure the stability of the position of the multiple batteries 4, and the positive electrodes of the multiple batteries 4 can be connected through the conductive plate I 2, and the negative electrodes of the multiple batteries 4 can be connected through the conductive plate II 3, so that the multiple batteries 4 form a lithium battery pack;

[0038] Furthermore, since the two assembly racks 1 are slidably connected to each other, the distance between the two assembly racks 1 can be adjusted, and different numbers of batteries 4 can be placed between the two assembly racks 1. At the same time, the compression spring I is fixedly connected between the two assembly racks 1, thereby ensuring that the two assembly racks 1 can effectively fix multiple batteries 4;

[0039] like Figures 1 to 10 As shown, the structure and function of a lithium battery are described in detail below;

[0040] A lithium battery comprises two mutually slidably connected combination frames 1, a compression spring I fixedly connected between the two combination frames 1, a conductive plate I2 and a conductive plate II3 fixedly connected to the inner sides of the two combination frames 1, a plurality of batteries 4 placed between the two combination frames 1, the combination frame 1 comprises a support frame 11, a sliding frame 12 is slidably connected to the left and right sides of the support frame 11, a compression spring II is fixedly connected between the two sliding frames 12, the upper end of the support frame 11 is fixedly connected to a limit plate I 13, the lower end of the support frame 11 is fixedly connected to a limit plate II 14, the upper end of the support frame 11 is fixedly connected to a support top plate 15, the lower end of the support frame 11 is fixedly connected to a support bottom plate 16, the two limit plates I 13 are slidably connected, the two limit plates II 14 are slidably connected, and a compression spring III is fixedly connected between the sliding frames 12 on the two combination frames 1;

[0041] The conductive plate I2 is provided with a plurality of protrusions 21, and the conductive plate II3 has the same structure as the conductive plate I2;

[0042] like Figure 2 As shown, when in use, multiple batteries 4 are placed between the two combination frames 1, and the two combination frames 1 tend to approach each other through compression spring I, thereby positioning the multiple batteries 4. At the same time, a sliding frame 12 that can slide is provided. The sliding frame 12 can slide on the support frame 11, thereby facilitating the installation and removal of the batteries 4. At the same time, a compression spring II is fixedly connected between the two sliding frames 12. The compression spring II pulls the two sliding frames 12 to ensure that the two sliding frames 12 clamp the multiple batteries 4, thereby ensuring the stability of the multiple batteries 4.

[0043] Further, such as Figure 5As shown, the two conductive plates I2 are in contact with each other, and the two conductive plates II3 are in contact with each other. When the number of batteries 4 changes, the two conductive plates I2 slide relative to each other, and the two conductive plates I2 are also clamped to maintain contact, thereby ensuring the series connection of the positive electrodes of the multiple batteries 4. The two conductive plates II3 slide relative to each other, and the two conductive plates II3 are also clamped to maintain contact, thereby ensuring the series connection of the negative electrodes of the multiple batteries 4.

[0044] Furthermore, a support top plate 15 and a support bottom plate 16 are provided to ensure that the two conductive plates I2 and the two conductive plates II3 can make good contact with the multiple batteries 4. The support top plate 15 and the support bottom plate 16 are provided to support the two conductive plates I2 and the two conductive plates II3, thereby ensuring that the two conductive plates I2 and the two conductive plates II3 do not deform and thus ensure good contact with the multiple batteries 4.

[0045] Furthermore, in order to ensure that the conductive plate I2 and the conductive plate II3 can have good contact with the multiple batteries 4, a protrusion 21 is provided on the conductive plate I2. The conductive plate II3 has the same structure as the conductive plate I2 and is also provided with a protrusion. The protrusion can contact the positive or negative electrode of the battery 4, thereby ensuring good contact with the multiple batteries 4.

[0046] In order to facilitate the preparation of conductive plates II3 and I2, a lithium battery processing device is designed. The structure and function of the lithium battery processing device are described in detail below.

[0047] A lithium battery processing device includes a processing bracket 5, a clamping mechanism I 6, a clamping mechanism II 7, a processing mechanism 8, a control mechanism 9, a screw 10 and a sensor 101;

[0048] The processing bracket 5 includes a processing base plate 51, a sliding track 52 and a groove 53. The sliding track 52 is fixedly connected to the processing base plate 51, and a plurality of grooves 53 are provided on the processing base plate 51.

[0049] The clamping mechanism I6 includes a clamping screw I61 and a clamping plate I62. The clamping screw I61 is rotatably connected to the processing base plate 51. The clamping plate I62 is slidably connected to the processing base plate 51. The clamping plate I62 is connected to the clamping screw I61 through a thread.

[0050] The clamping mechanism II 7 includes a clamping slider 71, a clamping screw II 72, and a clamping plate II 73. The clamping slider 71 is slidably connected to the processing base plate 51, the clamping screw II 72 is rotatably connected to the processing base plate 51, the clamping plate II 73 is slidably connected to the clamping slider 71, and the clamping plate II 73 is threadedly connected to the clamping screw II 72.

[0051] The processing mechanism 8 includes a processing slider 81, a telescopic mechanism 82, a stamping die 83 and a stamping protrusion 84. The processing slider 81 is slidably connected to the sliding track 52. The telescopic mechanism 82 is fixedly connected to the processing slider 81. The stamping die 83 is detachably fixedly connected to the telescopic end of the telescopic mechanism 82. The stamping die 83 is fixedly connected to two stamping protrusions 84.

[0052] The processing base plate 51 is rotatably connected to a screw rod 10, and the screw rod 10 is provided with a power mechanism I for driving it to rotate. The power mechanism I is preferably a servo motor. The processing slider 81 is connected to the screw rod 10 through a thread.

[0053] Two sensors 101 are fixedly connected to the processing base plate 51, one of which is connected to the power mechanism I, and the other is connected to the telescopic mechanism 82. The control mechanism 9 includes a control shaft 91 and a control cam 92. Four control cams 92 are loosely fitted on the control shaft 91. Each control cam 92 is provided with a positioning screw. The control cam 92 can contact the corresponding sensor 101. The control shaft 91 is provided with a power mechanism II that drives it to rotate. The power mechanism II is preferably a servo motor.

[0054] When in use, the conductive plate to be processed is placed on the processing base plate 51, and the clamping screw I 61 is rotated. When the clamping screw I 61 rotates, the clamping plate I 62 is driven to move through the thread. The clamping plate I 62 slides on the processing base plate 51 and moves downward. The clamping plate I 62 clamps the side of the conductive plate;

[0055] Push the clamping slider 71 to slide on the processing base plate 51. When the clamping slider 71 slides to the specified position, the clamping screw II 72 is rotated. When the clamping screw II 72 rotates, the clamping plate II 73 is driven to move through the thread. The clamping plate II 73 slides on the clamping slider 71. The clamping plate II 73 moves downward, and the clamping slider 71 clamps the middle part of the conductive plate.

[0056] After the conductive plate is clamped, the power mechanism II is started. The power mechanism II can be fixedly connected to the processing base plate 51. The output shaft of the power mechanism II drives the control shaft 91 to rotate, and the control shaft 91 drives the four control cams 92 to rotate. The four control cams 92 form two extrusion components. Each extrusion component corresponds to a sensor 101. The four control cams 92 are driven to rotate by the rotation of the control shaft 91. The four control cams 92 squeeze the two sensors 101. The sensors 101 can be contact sensors or pressure sensors. One of the sensors 101 is connected to the power mechanism I through the conventional electronic control means in this field, and the other sensor 101 is connected to the telescopic mechanism 82 through the conventional electronic control means in this field. By adjusting the misalignment angle of the two control cams 92 on each extrusion component, the time when each sensor 101 is squeezed can be adjusted, thereby controlling the movement time of the corresponding power mechanism I and the telescopic mechanism 82. After adjusting the position of the control cam 92, the position of the control cam 92 can be fixed by a positioning screw. The two extrusion components are misaligned with each other, that is, the two extrusion components squeeze the two sensors 101 separately.

[0057] When the extrusion component squeezes the sensor 101 that controls the rotation of the output shaft of the power mechanism I, the output shaft of the power mechanism I drives the screw 10 to rotate. When the screw 10 rotates, it drives the processing mechanism 8 to move laterally through the thread. By adjusting the misalignment angle of the two control cams 92 on each extrusion component, the time when each sensor 101 is squeezed can be adjusted, thereby controlling the movement time of the corresponding power mechanism I, and thus controlling the position of the processing mechanism 8 each time it moves.

[0058] When the extrusion component squeezes the sensor 101 that controls the telescopic mechanism 82, the telescopic mechanism 82 drives the stamping die 83 to move downward, and the stamping die 83 drives the two stamping protrusions 84 to move downward. The two stamping protrusions 84 are respectively located on the upper sides of the two grooves 53, thereby completing the processing of the protrusion 21;

[0059] The control mechanism 9 controls the screw rod 10 and the processing mechanism 8 to move alternately, thereby quickly completing the processing of the multiple protrusions 21 on the conductive plate I2 and the conductive plate II3.
