Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of battery electrolyte addition equipment, and more specifically, to an automatic batch addition equipment for battery electrolyte. Background Technology
[0002] Button batteries, also known as coin cells, are batteries shaped like small buttons. Due to their small size, button batteries are widely used in various microelectronic products, generally serving as backup power for electronic devices. They are one of the most commonly used and important components in electronic equipment. Existing button batteries include a negative electrode cap, a positive electrode shell, and a wound electrode assembly composed of a negative electrode sheet, a separator, and a positive electrode sheet. A sealing plastic ring is embedded around the outer periphery of the negative electrode shell. After the positive electrode shell and the negative electrode cap are assembled, the sealing plastic ring contacts the bottom of the positive electrode shell, providing a seal. The sealed space formed by the positive electrode shell and the negative electrode cap contains electrolyte, and the wound electrode assembly is located in the sealed space. In the button battery manufacturing process, the electrolyte is first added to the negative electrode cap before assembly.
[0003] Button batteries are typically button-shaped. Because of their small size and ability to store electrical energy, they are widely used in various microelectronic products for direct power supply or as backup power.
[0004] Currently, common electrolyte addition equipment on the market is shown in patent document CN201910599426.6, entitled "Fully Automatic Button Battery Electrolyte Addition Device." It includes a workbench with a frame at its bottom. The workbench is equipped with a material plate conveying and stacking mechanism and an automatic electrolyte addition mechanism. The material plate conveying and stacking mechanism includes a material plate conveying track, an infeed stacking rack, and an outfeed stacking rack. The automatic electrolyte addition mechanism includes vertical moving components, horizontal moving components, and an automatic electrolyte addition component. This addition device features an automatic electrolyte addition mechanism for automatically sucking and adding electrolyte, and a material plate conveying and stacking mechanism for mechanically conveying and stacking material plates. This achieves fully automatic mechanical addition of electrolyte to the material plates, overcoming the shortcomings of existing manual operation. It not only has high addition efficiency, meeting the needs of mass production, but also ensures that the amount of electrolyte added each time is the same, thus guaranteeing the uniformity of button battery quality.
[0005] However, after the button batteries in the aforementioned equipment material trays are filled with electrolyte, the material trays are stacked one on top of the other. Subsequently, the material trays need to be removed one by one to complete the battery assembly process. During the handling process, the electrolyte in the button batteries that have not been fully sealed in the material trays is prone to spilling out into the outside, affecting the battery quality and posing a risk of contaminating surrounding objects.
[0006] In addition, the material plates move forward by pushing each other forward and backward. Therefore, in order to add electrolyte to the button batteries in the end material plate, several empty material plates need to be set at the end of the feeding stack rack. The operation is relatively complicated and additional empty material plates need to be prepared.
[0007] Therefore, it is necessary to design and improve the structure of the automatic electrolyte addition equipment. Utility Model Content

[0030] To address the problem that currently used automatic battery electrolyte filling equipment stacks up the material plates containing button batteries after adding electrolyte, which can easily lead to electrolyte leakage during subsequent packaging processes and is also cumbersome, we provide an automatic batch filling equipment for battery electrolyte.

[0034] like Figure 1-4As shown, this embodiment provides an automatic batch filling device for battery electrolyte, including a feeding conveyor belt 1, a discharging conveyor belt 2, a pallet transfer assembly 3, a pallet gripping arm 4, and an automatic filling head 5. The pallet gripping arm 4 and the automatic filling head 5 are respectively disposed above both ends of the pallet transfer assembly 3. The feeding conveyor belt 1 and the discharging conveyor belt 2 are respectively disposed on the front and rear sides of the pallet transfer assembly 3 corresponding to one end of the pallet gripping arm 4. The pallet transfer assembly 3 includes a pallet holder 301, which is slidably sleeved on a reciprocating guide rail.
[0035] In this process, a material board filled with button batteries (not shown in the diagram) is fed into the front of the pallet transfer assembly 3 via the feeding conveyor belt 1. The pallet gripping arm 4 picks up the material board from the feeding conveyor belt 1 and places it onto the pallet transfer assembly 3. The pallet transfer assembly 3 then moves the material board to the automatic electrolyte filling head 5 at the other end. The automatic electrolyte filling head 5 is activated to add electrolyte to the button batteries in the material board. After the electrolyte filling is completed, the pallet transfer assembly 3 moves the material board back under the pallet gripping arm 4. The pallet gripping arm 4 removes the material board and places it onto the discharge conveyor belt 2, outputting the complete panel of button batteries with added electrolyte one by one, facilitating subsequent assembly processes.
[0036] The pallet gripping arm 4 includes a translational lifting base 401, on which vertically downward automatic grippers are mounted. The automatic grippers include a loading gripper 402 and a unloading gripper 403 positioned on the same horizontal line. The loading gripper 402 and the unloading gripper 403 can be simultaneously driven to translate and lift via the translational lifting base 401, thereby synchronously picking up and placing un-liquidated material plates on the feed conveyor belt 1 and liquid-filled material plates on the pallet holder 301, ensuring synchronized loading and unloading of material plates and improving equipment efficiency.
[0037] The translational lifting seat 401 has multiple loading grippers 402 arranged front and rear on one side of the feeding conveyor belt 1, and multiple unloading grippers 403 of the same number are arranged behind the loading grippers 402. Multiple pallet holders 301 are arranged on the reciprocating guide rail corresponding to the loading grippers 402. In addition to synchronous loading and unloading of material plates, multiple material plates can be arranged simultaneously for loading and unloading, and a corresponding number of pallet holders 301 can be arranged on the pallet transfer assembly 3 to further improve the production efficiency of the equipment.
[0038] The feeding conveyor belt 1 includes symmetrical conveyor belts 101 on both sides, and a lifting baffle 102 is provided between the two conveyor belts 101. Since the feeding grippers 402 arranged in a row need to grab multiple material plates at the same time, the lifting baffle 102 is provided in the feeding conveyor belt 1 to limit the arrangement of multiple feeding grippers 402 when they grab material plates, so as to ensure accurate alignment between the material plates and the feeding grippers 402.
[0039] Both ends of the automatic gripper are provided with tray grippers 6, and the inner side of the tray gripper 6 is provided with a tray slot 601. In this embodiment, the tray gripper 6 is forked on both sides so that the two tray grippers 6 can correspond to the four corners of the square material board, and the tray slot 601 is used to fit the side of the material board to ensure that the gripping process is stable and does not shake, effectively preventing the material board from loosening.
[0040] The tray holder 301 includes a concave groove 3011 and a raised edge 3012. A clearance notch 3013 is provided on the raised edge 3012 corresponding to the tray clamp 6. The concave groove 3011, in conjunction with the raised edge 3012, stably holds the material plate, preventing electrolyte leakage caused by material plate shaking during tray transfer assembly 3 operation. The clearance notch 3013 prevents the raised edge 3012 from obstructing the tray clamp 6 from picking up or placing the material plate from the concave groove 3011.
[0041] The reciprocating guide rail includes a first guide rail 302 and a second guide rail 303. A tray holder 301 is slidably sleeved on the first guide rail 302, and a lifting bracket 304 is slidably sleeved on the second guide rail 303. The tray holder 301 is installed on the lifting bracket 304. Tray holders 301 are provided at both ends of the tray transfer assembly 3, corresponding to the tray gripping arm 4 and the automatic liquid adding head 5, respectively. Therefore, it is unnecessary to perform the loading and unloading process after the automatic liquid adding head 5 completes the electrolyte addition; the liquid adding and loading / unloading processes can be performed separately, improving work efficiency.
[0042] The automatic electrolyte dispensing head 5 includes a multi-axis slide 501, on which multiple dispensing needles 502 connected to electrolyte storage tanks (not shown in the figure) are arranged in a row corresponding to the tray holder 301. Since the button batteries in the material plate are typically arranged in multiple rows, the number of dispensing needles 502 can be set to correspond to the number of each row on the material plate, allowing for rapid batch dispensing of electrolyte row by row.
[0043] During equipment operation, a material plate filled with button batteries without added electrolyte is placed into the feeding conveyor belt 1 and transported to the side of the pallet transfer assembly 3. During this process, the lifting baffle 102 rises to space the material plate according to the spacing of multiple loading grippers 402. Then, the loading grippers 402 grab the material plate and place it into one of the pallet holders 301 of the pallet transfer assembly 3. The pallet holder 301 moves to the other end, moving the material plate to below the automatic electrolyte filling head 5 for electrolyte filling. At the same time, another empty pallet holder 301 is moved from the automatic electrolyte filling head 5 to the loading gripper 402 where a material plate to be filled with electrolyte is placed. After the electrolyte filling is completed, the positions of the pallet holders 301 at both ends of the pallet transfer assembly 3 are reversed. The unloading gripper 403 places the material plate with added electrolyte into the discharge conveyor belt 2 for output, while the loading gripper 402 simultaneously places a new material plate into the pallet holder 301, and the automatic electrolyte filling head 5 at the other end continues to operate. In summary, after the material plates are placed into the pallet holders 301 at both ends, the loading, unloading and liquid filling processes are repeated until all material plates have been filled with liquid. After the last material plate is removed by the unloading gripper 403, the feeding conveyor belt 1 and the two pallet holders 301 return to an empty state.
[0044] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
