[0002] As a key component inside the battery, the battery separator mainly functions to prevent the positive and negative electrodes from directly contacting and causing a short circuit. During the installation process of the battery pack, a separator needs to be installed between each individual battery pack to ensure insulation between the batteries. With the continuous innovation of technology, the types of separators have also increased significantly. During the process of cutting and forming the separator, damage is inevitable. If it is not detected in time, abnormal separator quality will affect the quality of the final formed electric group. Currently, the placement process of lithium battery separators mainly relies on manual processing.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Example, refer to Figures 1 to 7 A turnover device for placing lithium battery separators, which includes an assembly table for lithium battery combinations and a suspended conveyor belt 1 for transporting separator accessories. The suspended conveyor belt 1 is a prior art and will not be described in detail here. The assembly table is composed of an assembly seat 2 and support frames 3 arranged on both sides of the assembly seat 2. A plurality of assembly units are arranged on the assembly table. The assembly unit includes a lower group plate 4 arranged on the assembly seat 2, and the assembly seat 2 is connected with an L-shaped assembly pressing plate 5 through an electric driving member;

[0030] It should be noted that when processing on the assembly table, the assembly table can be placed obliquely to ensure the stable storage of the battery pack. The battery packs are placed layer by layer on the lower group plate 4 through a robotic arm, and the L-shaped assembly pressing plate 5 connected through the electric driving member can move downward to press the battery packs, thereby ensuring the fixed position of the battery packs.

[0031] Furthermore, the electric drive component includes an electric track 12 opened on the assembly seat 2, and the electric track 12 and the driving slider 13 are adapted to achieve the effect of the driving slider 13 actively moving on the electric track 12. This is a prior art and will not be elaborated on here. A driving slider 13 is slidably arranged on the electric track 12, and the driving slider 13 is connected to the L-shaped assembly platens 5 on both sides through a T-shaped connecting rod 14, thereby driving the L-shaped assembly platens 5 to move up and down, thereby achieving the effect of transporting the battery partitions downward to the battery pack one by one.

[0032] A lithium battery test component is arranged on the L-shaped assembly plate 5. Furthermore, the lithium battery test component includes a terminal board 15 connected to a lithium battery voltage detector, which is an existing technology for detecting battery charging and discharging. The terminal board 15 is arranged on the side wall of the L-shaped assembly plate 5, and its terminal is connected to an elastic touch plate 16 for contacting with the lithium battery ear, so as to achieve the effect of testing the lithium batteries one by one when the lithium battery pack is pressed downward, thereby improving the quality control of each process.

[0033] The L-shaped assembly platen 5 is provided with an offset movable adjustment member for laterally moving the partition, and the offset movable adjustment member includes a plurality of groups of rubber movable wheels 17 arranged at the bottom of the L-shaped assembly platen 5, and the rubber movable wheels 17 in one group are connected by a linkage horizontal axis 18. The L-shaped assembly platen 5 is provided with an adjustment motor 19, and the output end of the adjustment motor 19 is connected to the linkage horizontal axis 18 through a worm gear assembly 20.

[0034] Furthermore, a transfer inner recess 21 for limiting the transfer of the partition is provided on the side wall at the turning point of the L-shaped assembly pressure plate 5. The transfer inner recess 21 is matched with the cutting transfer port 9 to respectively realize the clamping of the two ends of the partition. The clamping time is relative, that is, when the partition is gradually clamped at the transfer inner recess 21, the cutting transfer port 9 is in a state of gradually disengaging, thereby ensuring the stable transfer of the partition during the transfer process.

[0035] The assembly seat 2 is provided with a transfer groove 6, and a plurality of transfer grooves 6 are designed in the same row. A deflection twist cylinder 7 is provided at the bottom of the transfer groove 6. A twist motor 8 connected to the deflection twist cylinder 7 is provided on a side wall of the assembly seat 2. The twist motor 8 is used to drive the deflection twist cylinder 7 to rotate, so as to rotate the partition in the transfer port 9 thereon from a vertical state to a horizontal state, thereby realizing effective transportation and transfer of the partition;

[0036] The inner wall of the deflection torsion cylinder 7 is provided with a cutting and transferring opening 9 for inserting the partition board. The side wall of the assembly seat 2 above the transfer groove 6 is provided with a torsion force detecting member for detecting the partition board. Further, the torsion force detecting member includes a pressure test seat 22 arranged on the assembly seat 2. A U-shaped frame 23 is movably arranged in the pressure test seat 22. A contact roller 24 is arranged on the U-shaped frame 23. The pressure test seat 22 is provided with a pressure sensor 25 for detecting the compression strength of the U-shaped frame 23.

[0037] It should be noted that when a crack appears in the partition board, one end of the partition board is at the cutting and transferring opening 9. At this time, the torsion force applied to the partition board by the rotation of the cutting and transferring opening 9 is transmitted to the other end, which is different according to the integrity of the partition board. Therefore, when the torsion can be sensed by the pressure sensor 25, the integrity of the partition board during transfer can be detected by the different pressures received at the end of the partition board far from the cutting and transferring opening 9. That is, when there is a crack in the partition board, when the other end is twisted, the pressure applied to the contact roller 24 due to deformation will become smaller, so it can be effectively sensed by the pressure sensor 25.

[0038] A turnover cylinder 10 is arranged on the support frame 3. Further, a turnover motor is arranged on the support frame 3. The output end of the turnover motor is connected to the end of the turnover cylinder 10. A light-shielding annular cover 26 is arranged on the support frame 3. The setting of the light-shielding annular cover 26 can ensure the light-shielding effect during the detection of the light recognition device, and its inner diameter is adapted to the outer diameter of the turnover cylinder 10.

[0039] The turnover cylinder 10 is provided with a turnover slot opening 11 for storing the partition board. A light recognition device is arranged in the turnover slot opening 11 for detecting the integrity of the partition board. The suspended conveyor belt 1 is arranged directly above the turnover cylinder 10 to realize the conveying of the partition board. The light recognition device includes a light board 27 arranged on one side wall inside the turnover slot opening 11. A light overflow groove 28 is opened on the other side of the turnover slot opening 11. A light sensor is arranged in the light overflow groove 28. The light sensor is a prior art and will not be described in detail here. Through the setting of the above structure, the integrity of the partition board can be recognized. When the partition board is damaged, the light will penetrate through the partition board and be sensed by the light sensor in the light overflow groove 28.

[0040] When the present invention processes lithium batteries, the partition board is conveyed by the suspended conveyor belt 1 and is conveyed into the turnover slot opening 11 above the turnover cylinder 10. At this time, through the rotation of the turnover cylinder 10, the partition board in the turnover slot opening 11 is driven to rotate. During this process, the light board 27 arranged in the turnover slot opening 11 emits light, and the light is blocked by the partition board. At this time, when there is a defect in the partition board, the light will penetrate through the partition board and enter the light overflow groove 28, and be sensed by the light sensor, so as to realize the detection of the integrity of the partition board;

[0041] The partition within the turnover slot 11 will be conveyed into the transfer tank 6. At this time, the partition will gradually move into the transfer tank 6, and the bottom end of the partition will be inserted into the cutting transfer port 9 on the deflection torsion cylinder 7. At this time, the robotic arm drives the lithium battery pack to be placed on the lower group board 4 on the assembly seat 2. Under the action of the electric track 12 and the driving slider 13, it will drive the L-shaped assembly pressing plate 5 to move upward. At this time, the cutting transfer port 9 corresponds to the height of the transfer concave port 21. At this time, the deflection torsion cylinder 7 is controlled by the torsion motor 8 to rotate, and the partition is rotated from the vertical state to the horizontal state. During this process, the pressure sensor 25 senses different torsion pressures of the partition, and can detect whether the partition has cracks;

[0042] When it rotates to the horizontal state, the control adjustment motor 19 is rotated. Under the action of the worm and worm gear assembly 20, a plurality of rubber moving wheels 17 will drive the partition in the horizontal state to move horizontally, so that the partition moves from the cutting transfer port 9 to the transfer concave port 21 on the L-shaped assembly pressing plate 5. Thus, when the L-shaped assembly pressing plate 5 moves downward to the battery pack, the rubber moving wheels 17 reverse, driving the partition in the transfer concave port 21 to be automatically assembled with the battery pack, so as to achieve the effect of precise positioning and assembly.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
