Description

Technical Field

[0001] The utility model relates to the field of button batteries, in particular to an automatic button battery assembly system. Background Art

[0002] Existing button batteries have the advantages of high specific capacity, high voltage, small size, long storage time, good voltage stability, simple structure, low assembly cycle and cost. Therefore, button batteries are often used in laboratories for professional electrical performance testing. After verifying the performance of battery materials, they are reused in large batteries such as soft packs, square shells, and cylinders.

[0003] The existing button battery generally consists of a first electrode shell, auxiliary materials (such as nickel foam, gasket, spring), lithium sheet, diaphragm, positive electrode sheet, electrolyte, and second electrode shell. The existing button battery production equipment assembles button batteries in the following steps: first put in the first electrode shell, then put in the auxiliary materials in the first electrode shell, then put in the lithium sheet and add electrolyte in the first electrode shell, then put in the diaphragm and add electrolyte in the first electrode shell, then put in the electrode sheet in the first electrode shell, and finally put in the second electrode shell and seal it. However, when the material taking head of this existing button battery production equipment places the pole piece into the first pole shell, it is easy to place it inaccurately, resulting in insufficient concentricity between the pole piece and the first pole shell and the second pole shell. At this time, it is very easy to cause one side of the pole piece to deviate from the first pole shell. When the second pole shell is sealed, the second pole shell and the first pole shell will be misaligned, resulting in defective products, which greatly affects the production efficiency; and during the assembly process, the pole piece is easy to curl up and present a very curled state after contacting the electrolyte. The problem of positioning and maintaining the concentricity of the curled pole piece with the first pole shell and the second pole shell during assembly is a difficult point in the assembly. In addition, the diaphragm and lithium sheet are also prone to inaccurate placement when placed.

[0004] In view of the above problems, it is necessary to study an automatic assembly system for button batteries, which can effectively avoid the problem of inaccurate placement of the pole piece and difficulty in having sufficient concentricity with the first pole shell, thereby ensuring the assembly accuracy of the button battery.

[0068] The working mode of the button battery automatic assembly system of the utility model is:

[0069] In the first step, the material transfer device 2 is activated, so that the multiple vacuum suction heads 23 of the material transfer device 2 firstly absorb the first electrode shell a placed on the first electrode shell placement jig A, the auxiliary material c placed on the auxiliary material placement jig C, the lithium sheet d placed on the lithium sheet placement jig D, the diaphragm e placed on the diaphragm placement jig E, and the electrode f placed on the electrode placement jig F;

[0070] In the second step, the material moving device 2 is activated, and the first electrode shell a, auxiliary material c, lithium sheet d, diaphragm e and electrode f adsorbed by the material moving device 2 are all passed through the material visual recognition device 7. The material visual recognition device 7 recognizes the material contours of the first electrode shell a, auxiliary material c, lithium sheet d, diaphragm e and electrode f adsorbed by the material moving device 2 to confirm and record the center positions of the first electrode shell a, auxiliary material c, lithium sheet d, diaphragm e and electrode f adsorbed by the material moving device 2. At the same time, the material visual recognition device 7 identifies whether there are defects in the appearance of the first electrode shell a, auxiliary material c, lithium sheet d, diaphragm e and electrode f adsorbed by the material moving device 2. If there are no defects, the third step is entered; otherwise, the material moving device 2 discards the materials with appearance defects (such as the first electrode shell a, auxiliary material c and lithium sheet d) and re-adsorbs the corresponding materials from the material mechanism 3, and then repeats the second step;

[0071] In the third step, the material transfer device 2 is activated to stack the first electrode shell a, auxiliary material c and lithium sheet d adsorbed by the material transfer device 2 on the assembly fixture 41 of the assembly device 4 in sequence;

[0072] In the third step, the assembly translation device 42 of the assembly device 4 drives the assembly jig 41 to translate to the injection device 5, and the injection device 5 injects electrolyte into the lithium sheet d to perform the first injection. After the first injection is completed, the assembly translation device 42 of the assembly device 4 drives the assembly jig 41 to translate and reset;

[0073] In the fourth step, the material transfer device 2 places the diaphragm e adsorbed by the material transfer device 2 on the assembly jig 41 of the assembly device 4; then, the assembly translation device 42 of the assembly device 4 drives the assembly jig 41 to translate to the injection device 5, and the injection device 5 injects electrolyte into the diaphragm e for the second injection. After the injection is completed, the assembly translation device 42 of the assembly device 4 drives the assembly jig 41 to translate and reset; at the same time, the material transfer device 2 is actuated first, so that a vacuum suction head 23 of the material transfer device 2 absorbs the second pole shell b placed on the second pole shell placement jig B;

[0074] In the fifth step, the material moving device 2 is activated, and the second pole shell b adsorbed by the material moving device 2 passes through the material visual recognition device 7. The material visual recognition device 7 performs logistics contour position recognition on the second pole shell b adsorbed by the material moving device 2 to confirm the center position of the second pole shell b adsorbed by the material moving device 2. At the same time, the material visual recognition device 7 recognizes whether there is a defect in the appearance of the second pole shell b adsorbed by the material moving device 2. If the second pole shell b has no defect, the sixth step is entered; otherwise, the material moving device 2 discards the adsorbed second pole shell b and re-adsorbs the second pole shell b from the material mechanism 3, and then the fifth step is repeated;

[0075] In the sixth step, the material moving device 2 first places the pole piece f adsorbed by the material moving device 2 on the assembly jig 41 of the assembly device 4; then, the material moving device 2 places the second pole shell b adsorbed by the material moving device 2 on the assembly jig 41 of the assembly device 4. After the second pole shell b is placed, the material moving device 2 can apply pressure to the second pole shell b to pre-press the second pole shell b with the first pole shell a; finally, the assembly translation device 42 of the assembly device 4 drives the assembly jig 41 to translate to the pressing device 6, and the pressing device 6 completely presses the second pole shell b with the first pole shell a. After the complete pressing is completed, the assembly translation device 42 of the assembly device 4 drives the assembly jig 41 to translate and reset; at this time, the material moving device 2 can unload the assembled button batteries.

[0076] In the utility model, the utility model can perform logistics contour recognition on the first pole shell a, auxiliary material c, lithium sheet d, diaphragm e, pole piece f and second pole shell b adsorbed by the material moving device 2 through the material visual recognition device 7 to confirm the center position of the first pole shell a, auxiliary material c, lithium sheet d, diaphragm e, pole piece f and second pole shell b adsorbed by the material moving device 2, and then can control the material moving device 2 accordingly to place the first pole shell a, auxiliary material c, lithium sheet d, diaphragm e, pole piece f and second pole shell b to the placement position on the assembly jig 41, thereby ensuring the concentricity of the first pole shell a, auxiliary material c, lithium sheet d, diaphragm e, pole piece f and second pole shell b placed by the material moving device 2 on the assembly jig 41, and can effectively avoid the problems of inaccurate placement and insufficient concentricity of the first pole shell a, auxiliary material c, lithium sheet d, diaphragm e, pole piece f and second pole shell b, thereby ensuring the assembly accuracy of the button battery; wherein, materials with appearance defects can be placed in the waste material tank 11 set on the frame 1.

When it is necessary to replenish lithium sheets d, diaphragms e and electrode sheets f in the material taking area 30, first, the feeding translation device H2 drives the feeding plate H1 to translate from the material taking area 30 to the bottom of the material rack G1; then, the material storage lifting device G2 drives the material rack G1 to move downward so that the positioning hole I1 of the bottom supporting plate I on the material rack G1 is docked with the positioning block H11 of the feeding plate H1; then, the feeding translation device H2 drives the feeding plate H1 to translate from the bottom of the material rack G1 to the material taking area 30, thereby transferring the supporting plate I docked with the feeding plate H1 and the lithium sheet placement jig D, diaphragm placement jig E and electrode placement jig F placed on the supporting plate I to the material taking area 30. When the lithium sheets d, diaphragms e and pole pieces f placed on the lithium sheet placement jig D, diaphragm placement jig E and pole piece placement jig F on the material taking area 30 are used up, the lithium sheet placement jig D, diaphragm placement jig E and pole piece placement jig F on the material taking area 30 can be taken away by other unloading mechanisms (such as a robot) or manually.

The working mode of the first pole shell placement jig A and the first pole shell loading device J is as follows: initially, the first pole shell lifting column J2 is aligned with a first pole shell placement hole A1 of the first pole shell placement jig A; before the material moving device 2 is about to adsorb the first pole shell a, the first pole shell lifting device J3 drives the first pole shell lifting column J2 to move upward and pushes the topmost first pole shell a in the first pole shell placement hole A1 aligned with the first pole shell lifting column J2 out to the position where the material moving device 2 is about to adsorb the first pole shell a, to ensure that the material moving device 2 can adsorb the first pole shell a; when the first pole shell a in the first pole shell placement hole A1 aligned with the first pole shell lifting column J2 is taken out, the first pole shell lifting device J3 drives the first pole shell lifting column J2 to move down and reset, and then the first pole shell jig rotating device J1 drives the first pole shell placement jig A to rotate until the other first pole shell placement holes A1 of the first pole shell placement jig A with the first pole shell a placed therein are aligned with the first pole shell lifting column J2.
