Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic assembly equipment for storage batteries, and in particular to a storage battery casting and welding method and a casting and welding machine. BACKGROUND

[0002] In the manufacturing process of lead-acid storage batteries, casting and welding is a crucial process. In the existing casting and welding method for lead-acid storage batteries, the busbar mold is immersed in the lead liquid of the lead furnace, so that the cavities on the busbar mold are filled with lead liquid. Then the busbar mold is taken out of the lead furnace, and the battery bottom box containing multiple groups of poles is inverted on the busbar mold, so that the pole tabs of the multiple groups of poles are inserted into the lead liquid in the cavities of the busbar mold for casting and welding. After cooling the busbar mold, the battery bottom box is taken out of the busbar mold.

[0003] The complete casting and welding of the storage battery generally includes the processes of bottom mold heating, bottom mold lead pouring, casting and welding of the busbar, welding of the terminal, removal of the protective cap, and storage battery demolding, turning over and secondary shell entering. The processes of heating and pouring lead for the bottom mold, and placing and welding the terminal are all operation processes for the bottom mold, and the storage battery does not participate in this process. The storage battery and the bottom mold are connected during casting and welding, and after the casting and welding demolding is completed, the storage battery and the bottom mold are separated again. The casted and welded storage battery then enters the processes of turning over, secondary shell entering and removing the protective cap, and the demolded bottom mold continues the processes of bottom mold heating, bottom mold lead pouring and the like. In the patent No. 201720833432.X applied by the applicant, the moving operation processes for the bottom mold (bottom mold heating and bottom mold lead pouring) and the moving operation processes for the storage battery (material taking, turning over and secondary shell entering) are all completed in a straight line translation path, and the corresponding stations are arranged in a straight line. This method has some shortcomings. After the storage battery and the bottom mold are connected and welded at the casting and welding station, the storage battery and the bottom mold are separated, the bottom mold needs to be translated back to the starting heating and pouring station, and the storage battery is translated to the next turning over, secondary shell entering and protective cap removing station. This results in a long waiting time for the next round of casting and welding process, and the efficiency is relatively low. If the waiting time is to be reduced, multiple sets of translation and grabbing mechanisms for the bottom mold or the storage battery need to be designed and controlled respectively, and there should be no interference in the structure, which results in a complex structure of the whole machine and a large floor area.

[0004] Therefore, it is of great significance to provide a storage battery casting and welding method and a casting and welding machine with high efficiency and relatively simple and compact structure in the field. SUMMARY

[0022] In order for those of ordinary skill in the art to fully understand the content of the present application, the content of the present application is further described below in conjunction with the drawings and specific embodiments.

[0023] As Figure 1 A battery casting and welding method is shown, a bottom mold rotating workbench 1 and a battery translating workbench 2 are respectively arranged, the bottom mold 3 is placed on the bottom mold rotating workbench 1 and moves with the rotation thereof, the battery 4 moves linearly and translates through the battery translating workbench 2, the rotating route of the bottom mold rotating workbench 1 and the linear translating route of the battery translating workbench 2 are tangent, the bottom mold rotating workbench 1 and the battery translating workbench 2 coincide at a battery casting and welding station 101, when the bottom mold 3 rotates with the bottom mold rotating workbench 1 to the battery casting and welding station 101, the battery 4 reaches the battery casting and welding station 101 through the battery translating workbench 2 to complete the casting and welding of the battery 4.

[0024] In this embodiment, the bottom mold rotating workbench 1 rotates to drive the bottom mold 3 to move, after the casting and welding of the bottom mold 3 and the battery 4 is completed, the bottom mold 3 can directly rotate to start the next round of bottom mold lead injection, heating and other processes without returning to wait for the movement of the battery 4. The battery 4 normally translates to enter the subsequent processes of turning over and secondary shell entering. The rotating movement of the bottom mold 3 and the translation of the battery 4 can be parallel, only the time of each is controlled to coincide at the battery casting and welding station 101, so that the battery 4 can be docked with the bottom mold 3 to complete the casting and welding, and the efficiency is greatly improved.

[0025] The terminal placing station 102, the bottom mold heating station 103 and the lead injection station 104 are arranged on the bottom mold rotating workbench 1 and respectively place the bottom mold 3, the bottom mold 3 rotates to the battery casting and welding station 101 after completing the terminal placing, the bottom mold heating and the bottom mold cavity lead injection of the bottom mold rotating workbench 1;

[0026] The material taking station 201, the turning over station 202 and the secondary shell entering station 203 are arranged on the battery translating workbench 2, the battery 4 translates to the battery casting and welding station 101 after taking the material, vertically descends to immerse into the bottom mold cavity to complete the casting and welding, and vertically ascends to demold after the casting and welding, the demolded bottom mold 3 rotates to the terminal placing station 102 with the bottom mold rotating workbench 1, and the bottom mold 3 on the lead injection station 104 rotates to the battery casting and welding station 101; the demolded battery 4 translates to the turning over station 202 to complete the turning over and the secondary shell entering station 203 to complete the secondary shell entering.

[0027] In this embodiment, the terminal placement station 102, the bottom mold heating station 103, the lead injection station 104, and the battery casting and welding station 101 on the bottom mold rotating worktable 1 form a four-station layout at 90°. Each station holds the bottom mold 3. The bottom mold 3 rotates to the corresponding station to complete the corresponding process, while the station remains stationary. Thus, rotating the bottom mold 3 90° completes one terminal placement, bottom mold heating, lead injection, and battery casting and welding process. Compared to the prior art, the process is simplified. In the prior art, after the bottom mold 3 is injected with lead and the battery is completed, welding of the terminals is still required. In this embodiment, the terminal placement process is completed in advance during the lead injection of the battery. After lead injection, the terminals and busbars are immersed in molten lead together. The terminals and the busbars of the battery 4 are integrally welded at the battery casting and welding station 101, eliminating the subsequent terminal welding process and further improving efficiency.

[0028] In order to enable the battery 4 to be quickly demolded after casting and welding, a water spraying and cooling mechanism 5 is set below the bottom mold rotating worktable 1 and the battery casting and welding station 101. After the battery 4 is immersed in the bottom mold cavity and the casting and welding is completed, the water spraying and cooling mechanism 5 sprays water to cool the bottom mold 3.

[0029] The lead injection station 104 is equipped with a high-level lead furnace 6 and a quantitative lead injection device 7. The high-level lead furnace 6 supplies molten lead to the quantitative lead injection device 7 using gravity. The molten lead is quantitatively injected into the cavity of the bottom mold 3 through the quantitative lead injection device 7. As mentioned above, the reason why the prior art requires a separate process to weld the terminals to the poles is that in the prior art, the bottom mold is immersed in the lead furnace as a whole. If the terminals are placed on the bottom mold 3 at this time, the terminals will be detached due to the buoyancy of the molten lead in the lead furnace. In this embodiment, the high-level lead furnace 6 supplies molten lead, and the quantitative lead injection device 7 controls the injection volume of molten lead to be accurately injected into the cavity of the bottom mold 3. In this way, the position of the terminals in the pole cavity of the bottom mold 3 remains unchanged, which facilitates the integral welding of the bus and the terminal pole during subsequent casting and welding.

[0030] On the battery translation workbench 2, a flux application station 204 and a mopping station 205 are also set on one side of the material pick-up station 201. After the battery 4 passes through the material pick-up station 201, it picks up the flux and wipes the flux at the mopping station 205 before entering the battery casting and welding station 101 for casting and welding.

[0031] Another implementation, for example Figure 2 The image shows a battery casting and welding machine using the above method, including a bottom mold rotating worktable 1 and a battery translation worktable 2. The bottom mold 3 is placed on the rotating worktable 1 and rotates with it. The battery translation worktable 2 drives the battery 4 to move linearly. The rotation path of the bottom mold rotating worktable 1 and the linear translation path of the battery translation worktable 2 are tangent. The bottom mold rotating worktable 1 and the battery translation worktable 2 coincide at the battery casting and welding station 101.

[0032] In this embodiment, the battery rotary workbench 1 includes a rotary disk 11, and the bottom mold 3 is placed on the rotary disk 11. The rotary disk 11 includes a terminal placement station 102, a bottom mold heating station 103, a lead injection station 104, and a battery casting and welding station 101. A rotary drive mechanism is located below the rotary disk 11 to drive it to rotate.

[0033] The battery translation worktable 2 includes a translation bracket 21 and a battery gripping mechanism 22. The battery gripping mechanism 22 can vertically lift and lower to grip the battery 4. The battery gripping mechanism 22 can slide and translate along the translation bracket 21. The battery translation worktable 2 includes a material picking station 201, a flipping station 202, and a secondary casing insertion station 203. The battery gripping mechanism 22 grips the battery 4 from the material picking station 201 and translates it along the translation bracket 21 to the battery casting and welding station 101 to complete the casting and welding. Then, it grips the battery 4 and translates it to the flipping station 202.

[0034] like Figure 3 As shown, a demolding frame 23 is also suspended on the translation support 21 above the battery casting and welding station 101. The demolding frame 23 includes a demolding platform 231, which is connected to a demolding lifting device 232. After the battery 4 is placed on the demolding platform 231 and lowered into the cavity of the bottom mold 3 to complete the casting and welding, the demolding lifting device 232 drives the battery 4 to rise to complete the demolding. The battery gripping mechanism 22 grips the battery 4 and lifts it up, then moves it along the translation support 21 to the flipping station 202.

[0035] The demolding platform 231 is suspended on the translation bracket 21 by the guide rod 233. A mounting base plate 234 is also provided below the demolding platform 231. The demolding lifting device 232 is fixed on the mounting base plate 234. The guide rod 233 passes through the demolding platform 231 and is fixedly connected to the mounting base plate 234. The free end of the demolding lifting device 232 is connected to the back of the demolding platform 231.

[0036] The demolding platform 231 is also connected to the translation slide rail 235. The translation slide rail 235 is equipped with the clamping mechanism 236. After the clamping mechanism 236 moves with the translation slide rail 235 to above the battery 4, it can descend vertically to press down on the battery 4, so that the battery 4 is immersed in the cavity of the bottom mold 3.

[0037] Obviously, the above-described embodiments only illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
