[0044] The assembly tray 2 is driven to move by the sliding device 3 and cooperates with the assembling mechanism 6, the liquid adding mechanism 7 and the sealing mechanism 8 to realize the button battery assembly operation of the finished parts composed of the parts to be assembled, and by setting several material trays 4 in a stackable manner and cooperating with the electromagnetic grasping mechanism 5 to transfer the material tray 4, multiple groups of material trays 4 that can be used for different purposes can be stacked, that is, the stacking of multiple empty material trays, the stacking of multiple material trays with parts to be assembled and the stacking of multiple finished parts material trays, which can realize the assembly of large quantities of button batteries, effectively reduce the overall volume, shorten the stroke of each structure when cooperating, increase the assembly speed, and effectively improve the efficiency of batch button battery assembly.

[0045] In one embodiment of the present invention, the electromagnetic gripping mechanism 5 includes:

[0046] The electromagnetic connector 51 is arranged on the supporting platform 1 through the first three-axis displacement device 52;

[0047] The electromagnetic grabbing frame 53 is used to be detachably connected to the electromagnetic connector 51 , and the electromagnetic grabbing frame 53 is detachably connected to the material tray 4 .

[0048] After the electromagnetic connector 51 is driven to engage with the electromagnetic grabbing frame 53 by the first three-axis displacement device 52, the electromagnetic grabbing frame 53 is driven to engage with the material tray 4, and the first three-axis displacement device 52 drives the material tray 4 to move, thereby realizing the stacked three-dimensional scheduling of multiple groups of material trays 4, achieving a reduction in floor space and a significant improvement in scalability.

[0049] Furthermore, the electromagnetic grabbing frame 53 is provided with a magnetic contact for combining with the electromagnetic connector 51. The electromagnetic grabbing frame 53 is provided with multiple electromagnets, and the material tray 4 is provided with multiple corresponding magnet sheets. The connection between the material tray 4 and the electromagnetic grabbing frame 53 is achieved through the attraction of the electromagnets and the magnet sheets.

[0050] In one embodiment of the present invention, the assembling mechanism 6 includes:

[0051] A connecting frame 61 connected to the first three-axis displacement device 52;

[0052] The suction cup device 62 is connected to the connecting frame 61 , and a plurality of suction cup heads are provided on the suction cup device 62 .

[0053] The connecting frame 61 is driven to move by the first three-axis displacement device 52, thereby driving the suction cup device 62 to move synchronously.

[0054] In one embodiment of the present invention, the liquid adding mechanism 7 comprises:

[0055] The conveying device 71 is provided on the supporting platform 1 and is provided with a plurality of sample bottles 72 , which are used to place different types of electrolytes;

[0057] Several electrolyte formulas need to be tested in the experiment. By adjusting the positions of several sample bottles 72 through the conveying device 71, the pipetting head 73 can be quickly made to correspond to the sample bottle 72 with the required electrolyte. The second three-axis displacement device 74 drives the position of the pipetting head 73, so that the pipetting head 73 can perform electrolyte absorption and injection operations.

[0058] In one embodiment of the present invention, a mounting frame 75 is provided on the support platform 1 , and a plurality of gun tips are provided on the mounting frame 75 . The gun tips are used to be detachably connected to the pipetting head 73 .

[0059] By arranging a number of gun tips on the mounting frame 75, the pipette head 73 is first driven to insert and dock with a new gun tip before the pipette head 73 performs the electrolyte aspiration operation, and the new gun tip aspirates the electrolyte. This avoids the risk of electrolyte mixing and contamination, and at the same time avoids the waste of samples caused by flushing the needle and filling the pipeline in the existing fixed pipeline method.

[0060] In one embodiment of the present invention, a waste liquid tank 76 is provided on the support platform 1 , and the waste liquid tank 76 is used to collect the remaining electrolyte in the gun tip.

[0061] After the gun tip is used, the gun tip is transferred to the waste liquid tank 76 and the pipetting head 73 is operated to discharge the residual waste liquid in the gun tip into the waste liquid tank 76 to achieve the collection of the waste liquid.

[0062] In one embodiment of the present invention, a waste tank 77 is provided on the support platform 1 , and the waste tank 77 is used to collect used gun tips.

[0063] After the gun head is used, the second three-axis displacement device 74 can be used to drive the gun head to move laterally and hit the waste tank 77 so that the gun head is loosened and falls off.

[0064] In one embodiment of the present invention, a plurality of first protrusions 41 and a plurality of grooves 42 are provided on the material tray 4 , and two adjacent material trays 4 are inserted into each other through the plurality of first protrusions 41 and the plurality of grooves 42 .

[0065] In one embodiment of the present invention, a plurality of second protrusions 9 are provided on the support platform 1, and the second protrusions 9 are used to be inserted into the grooves 42. The plurality of second protrusions 9 form parts placement positions, finished product placement positions and empty tray placement positions for placing a plurality of material trays 4.

[0066] In one embodiment of the present invention, a controller is further included for controlling the sliding device 3, the electromagnetic gripping mechanism 5, the assembling mechanism 6, the liquid adding mechanism 7 and the sealing mechanism 8 to coordinate and cooperate in assembling the battery button.

[0067] This invention solves the problems of low efficiency (10 pieces / hour) and large batch deviation (>12%) of traditional manual assembly, increases the button battery assembly speed to nearly 200 pieces / hour, compresses the capacity deviation to ±2%, reduces the cost of each unit by more than 70%, and reduces the deployment space to about 50% of the existing system through the design of four groups of three-dimensional material trays. In addition, a new liquid processing method is used to increase the number of electrolyte types that can be tested and verified in a single experiment to a maximum of 64.

[0068] Workflow:

[0069] Multiple material trays 4 with parts to be assembled are stacked on the parts placement position, and an empty material tray 4 is placed at the finished product placement position. The sliding device 3 drives the assembly tray 2 to approach the first three-axis displacement device 52, and the first three-axis displacement device 52 drives the suction cup device 62 to suck a group of parts to be assembled to the top of the assembly tray 2, and places the parts to be assembled in sequence. At the same time, the second three-axis displacement device 74 drives the pipetting head 73 to connect to the new gun head and absorb the required electrolyte. The sliding device 3 drives the assembly tray 2 with parts to be assembled to approach the second three-axis displacement device 74, and the second three-axis displacement device 74 drives the pipetting head 73 to be located above the assembly tray 2 and fill the electrolyte. After filling, the remaining electrolyte is discharged to the waste liquid tank 76, and the gun head is discharged to the waste material tank 77. After the parts to be assembled and the electrolyte on the assembly tray 2 are combined, the sliding device 3 drives the assembly tray 2 to the sealing mechanism for sealing operation.

[0070] When the topmost tray 4 on the part placement position is empty, the first three-axis displacement device 52 drives the electromagnetic connector 51 to engage with the electromagnetic grabbing frame 53, and the electromagnetic grabbing frame 53 is combined with the attracting magnet on the empty tray 4 to grab the tray 4 and place the tray 4 to the empty tray placement position, and then the assembly operation of the parts to be assembled on the next tray 4 is carried out.
