Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery cast welding, and in particular relates to a lead-acid battery cast welding device and method. Background Art

[0002] The main components of lead-acid batteries are positive plates, negative plates, electrolyte, diaphragm, battery cell and cover, among which the positive plates and negative plates are both composed of grids and active materials; the grid is used to support the active materials and also plays a conductive role. Generally, lead-antimony alloy is used, and pure lead or other lead alloys can also be used; when in the charging state, the active material of the positive plate is lead dioxide, and the active material of the negative electrode is spongy lead. When in the discharging state, the active materials of the positive and negative electrodes are both lead sulfate.

[0003] The positive plates and negative plates are arranged alternately, and a separator is placed between the positive plates and the negative plates. Several positive plates and negative plates constitute a pole group, which is installed in an insulated battery slot. The side plates are generally negative plates. Both the positive plates and the negative plates have pole ears. The pole ears of the same polarity are welded together to form a bus. Adjacent buses of different polarities are connected by a cross bridge. The bus is provided with poles extending out of the battery cover for external power supply or electrical equipment.

[0004] For example, the Chinese invention patent with Chinese application number 200910252982.2 discloses a battery cast welding production device and its production process for the battery industry: it includes a brush device, an impregnation device, and a cast welding main machine, and the brush device and the impregnation device are connected in sequence through a battery conveyor line; the brush device includes a brush main board with an ejection cylinder and a wire brush with a brush cylinder. Although the cast welding device is provided with a cast welding pre-treatment device, namely an impregnation device, which matches the cast welding machine, the impregnation device of the device still has many shortcomings. In the impregnation device, the flux liquid is absorbed by a sponge. When the battery is stained with the flux liquid in the impregnation device, the entire battery electrode group is in contact with the sponge. When used for a long time, the sponge is easily damaged by the pole ear, and then it is easy to cause uneven adhesion of the flux liquid on the pole group and the pole ear in the subsequent process. At the same time, the entire battery electrode group is in contact with the sponge, which will cause the flux liquid to be adhered to other places besides the pole group and the pole ear, and there is no device to process the excess flux liquid, which not only causes a waste of flux liquid, but also there is no special drying device to dry it after being immersed in the flux liquid in the impregnation device, affecting the working efficiency of the entire cast welding process.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] See also Figure 1 As shown, the present invention is a lead-acid battery cast welding equipment, including a flux impregnation device 3, a flux absorption device 4 and a drying device 5 which are arranged in sequence, and then when in use, the above devices are used to sequentially impregnate the battery after brushing, absorb excess flux, and dry the tabs, and finally the battery that has completed the above pre-treatment is sent into the cast welding machine body 2 for cast welding.

[0036] Based on the above requirements, such as Figure 1 In order to facilitate the control of the battery to be processed in sequence through the flux impregnation device 3, the flux absorption device 4 and the drying device 5, the present invention provides a circular track 1 directly above the flux impregnation device 3, the flux absorption device 4 and the drying device 5, and an electric slider A11 is provided on the circular track 1, and a manipulator A12 is connected to the electric slider A11, so that when in use, the manipulator A12 grabs the battery and moves it along the flux impregnation device 3, the flux absorption device 4 and the drying device 5.

[0037] At the same time, for the convenience of use, the battery is automatically controlled to be sent into the cast welding machine body 2 for cast welding. A battery conveyor line 10 is arranged directly below the circular track 1 at the end of the drying device 5, and a linear guide rail 101 is arranged above the battery conveyor line 10. The linear guide rail 101 is provided with an electric slider B102, and the electric slider B102 is connected with a manipulator B103. When in use, the manipulator A12 is controlled to place the battery on the battery conveyor line 10, and then the manipulator B103 is used to grab the battery and put it into the cast welding machine body 2 for cast welding.

[0038] It can be known that when the battery is processed by using the flux impregnation device 3, the flux absorption device 4 and the drying device 5, the battery pole ears need to be set downward. At this time, the battery cannot be directly placed on the battery conveyor line 10 for transportation. At this time, the battery needs to be flipped over and controlled with its bottom end facing downward so that it can be placed on the battery conveyor line 10 for transportation. At the same time, when using the cast welding machine body 2 for cast welding, the battery pole ears also need to be controlled to be set downward. Then, when using the manipulator B103 to grab the battery, it is necessary to control the battery to be flipped before grabbing, and then control the bottom end of the battery to face upward after flipping.

[0039] That is, based on the above requirements, such as Figure 1 As shown, a flipping mechanism A and a flipping mechanism B for controlling the flipping of the battery are also provided above the battery conveyor line 10; the flipping mechanism A is provided at one end of the battery conveyor line 10 close to the circular track 1, and the flipping mechanism B is provided at one end of the battery conveyor line 10 close to the circular track 1, wherein the flipping mechanism A is provided in cooperation with the manipulator A12, and the flipping mechanism B is provided in cooperation with the manipulator B103; at the same time, the flipping mechanism A and the flipping mechanism B have the same structure, both of which include a linear module 6 provided in the vertical direction, a rotating motor is provided on the slider of the linear module 6, and the end of the rotating motor is connected to the U-shaped groove plate 62, and the two inner side walls of the U-shaped groove plate 62 are provided with a clamping cylinder 63, and the end of the clamping cylinder 63 is connected to the clamping plate 64.

[0040] Furthermore, based on the above settings, when in use, first control the manipulator A12 to move above the battery conveyor line 10, then control the linear module 6 of the flipping mechanism A to drive the U-shaped groove plate 62 to move upward until it is sleeved on the outside of the battery, control the clamping cylinder 63 to extend and use the clamping plate 64 to clamp the battery, and after removing the manipulator A12, control the rotating motor to rotate 180°; then control the linear module 6 of the flipping mechanism A to drive the U-shaped groove plate 62 to move downward to release the battery onto the battery conveyor line 10, and drive the battery to move under the action of the battery conveyor line 10; in order to facilitate the use of the U-shaped groove plate 62 of the flipping mechanism A to control the clamping cylinder 63 to extend and use the clamping plate 64 to clamp the battery, control the linear module 6 of the flipping mechanism A to drive the U-shaped groove plate 62 to move upward, control the rotating motor to rotate 180°, and then use the manipulator B103 to grab the battery.

[0041] It is understandable that, in a possible implementation manner, in order to facilitate the soldering flux dipping of the battery tabs, as Figure 2-3 The solder flux impregnation device 3 provided by the present invention comprises a box 30 for storing solder flux, wherein a lifting impregnation tank 31 is arranged in the box 30, and a plurality of openings 311 are opened on the bottom side of the impregnation tank 31; a guide tube 33 is connected to the bottom side of the box 30 directly below the openings 311 through a connecting block 32, and a damping plug 34 is arranged in the guide tube 33 to slide along the inside thereof, and a connecting rod 35 penetrating the openings 311 is connected to the top of the damping plug 34, and the top of the connecting rod 35 A sealing plate 36 is connected to the top of the dipping tank 31. When the battery is moved to the top of the flux dipping device 3 during use, the dipping tank 31 is controlled to move upward until the battery tab is inserted into the dipping tank 31. Through the setting of the dipping tank 31, the depth of the flux in the dipping tank 31 is limited, so that when the depth of the flux is deep, the tab is controlled to be inserted into the flux liquid to avoid fluctuations in the flux liquid level, which may easily cause the flux to stick not only to the tab but also to other positions.

[0042] In order to control the dipping tank 31 to move up and down in the vertical direction, Figure 2 The top of the immersion tank 31 is connected to an L-shaped connecting plate 37, the top of the L-shaped connecting plate 37 is higher than the end surface of the opening end of the box body 30, and one side protrudes from the box body 30; the outer wall of the box body 30 is provided with a mounting plate 38, and a telescopic cylinder A39 is fixed on the mounting plate 38, and the end of the telescopic cylinder A39 is connected to the L-shaped connecting plate 37.

[0043] Meanwhile, in the above disclosed contents of the present invention, by means of the arrangement of the connecting rod 35, the sealing plate 36 and the damping plug 34, when the upward movement of the dipping tank 31 is controlled during use, the sealing plate 36 always abuts against the opening 311, so as to prevent the soldering flux in the dipping tank 31 from flowing out from the opening 311 after the dipping tank 31 is separated from the liquid surface of the box body 30 during the upward movement; at the same time, after the dipping tank 31 is used to immerse the battery in the soldering flux, the dipping tank 31 is controlled to move downward, At this time, due to the damping of the damping plug 34 and the guide tube 33, the downward movement speed of the immersion tank 31 is greater than the downward movement speed of the sealing plate 36. At this time, the sealing plate 36 is detached from the opening 311, and then when the immersion tank 31 is higher than the liquid level in the box body 30, the flux in the immersion tank 31 flows out from the opening 311; when the immersion tank 31 is immersed below the liquid level in the box body 30, the flux in the box body 30 flows into the immersion tank 31, thereby completing the replacement of the flux.

[0044] It is understandable that, in a possible implementation manner, in order to facilitate the drying of the excess soldering flux attached to the battery tab, as Figure 4-5 The flux absorption device 4 provided by the present invention includes a tray 40, and the bottom of the tray 40 is connected to a plurality of vertically arranged negative pressure exhaust pipes 41, one side of the negative pressure exhaust pipe 41 is connected to a branch pipe 411, and the branch pipe 411 is connected to the exhaust device; when in use, the exhaust device is used to form a negative pressure at the negative pressure exhaust pipe 41 at the bottom of the tray 40, and the negative pressure is used to extract the excess flux attached to the tab.

[0045] Of course, in order to recycle the extracted flux, Figure 5-6A convex ring 42 is provided at the top of the negative pressure exhaust pipe 41, and a concave portion A421 which is concave upward is provided at the opening of the bottom side of the convex ring 42; a movable rod 422 is penetrated by the convex ring 42, and the top of the movable rod 422 is connected to a cross bar 423, and both ends of the cross bar 423 are connected to a guide ring 424 which slides along the inside of the negative pressure exhaust pipe 41, and the bottom end of the movable rod 422 is connected to an upper pressing plate 425; a support box 43 is provided just below the tray 40, and a telescopic cylinder B47 is provided between the support box 43 and the tray 40, and a drainage pipe 44 is connected to the upper surface of the support box 43, and the end of the drainage pipe 44 is connected to a lower pressing plate 45 which moves along the axial direction of the negative pressure exhaust pipe 41, and a plurality of flow channels 451 which are connected to the drainage pipe 44 are provided on the lower pressing plate 45, and one end of the flow channel 451 penetrates the upper surface of the lower pressing plate 45; A support ring 414 is provided in the negative pressure exhaust pipe 41 below the branch pipe 411, and a downwardly recessed portion B415 is provided at the opening on the upper surface of the support ring 414; the negative pressure exhaust pipe 41 located above the branch pipe 411 is filled with a water-absorbing sponge 410 or water-absorbing cotton. When in use, after the excess flux attached to the battery pole ear is absorbed by the flux absorption device 4, the telescopic cylinder B47 is controlled to contract and drive the tray 40 to move downward. At this time, the drainage pipe 44 moves relative to the negative pressure exhaust pipe 41, and the water absorbed in the water-absorbing sponge 410 or water-absorbing cotton is squeezed out by the cooperation of the lower pressure plate 45 and the upper pressure plate 425, and is guided to the inside of the support box 43 through the drainage pipe 44; at the same time, the bottom side of the upper pressure plate 425 is connected to a breathable plate 426 with a diameter equivalent to the inner diameter of the negative pressure exhaust pipe 41.

[0046] In order to prevent the extruded flux adsorbed in the absorbent sponge 410 or the absorbent cotton from being discharged under the action of gravity during the vacuuming process using the negative pressure vacuum pipe 41, the present invention also provides a limiting ring 412 on the inner wall of the negative pressure vacuum pipe 41 above the branch pipe 411, and a movable ring 413 is provided above the limiting ring 412 and is movable along the inner sealing of the negative pressure vacuum pipe 41; the inner diameter of the limiting ring 412 is larger than the diameter of the lower pressure plate 45, and the inner diameter of the movable ring 413 is smaller than the diameter of the lower pressure plate 45.

[0047] Furthermore, the diameter of the recessed portion A421 is equivalent to the outer diameter of the upper pressure plate 425, the thickness of the upper pressure plate 425 is equivalent to the depth of the recessed portion A421, and the two are sealed together after the upper pressure plate 425 is inserted into the interior of the recessed portion A421; the diameter of the recessed portion B415 is equivalent to the outer diameter of the lower pressure plate 45, the thickness of the lower pressure plate 45 is slightly lower than the depth of the recessed portion B415, and the two are sealed together after the lower pressure plate 45 is inserted into the interior of the recessed portion B415.

[0048] The bottom side of the support box 43 is connected to a return pipe 46 , and a filter layer 431 is laid on the bottom of the support box 43 .

[0049] It is understandable that, in a possible implementation manner, in order to facilitate drying of the excess soldering flux attached to the battery tab, as Figure 7 As shown, the drying device 5 provided by the present invention includes a base plate 50, the bottom side of the base plate 50 is connected to a telescopic cylinder C51 for controlling its lifting and lowering, and the upper surface of the base plate 50 is recessed downward to form a slot 52 for inserting the pole ear; the two opposite inner walls of the slot 52 are both provided with jet holes; the jet holes are connected to the air supply channel set in the base plate 50, and the air supply channel is connected to the heat source air supply system.

[0051] Step 1, control the manipulator A12 to grab the battery that has been brushed, and then control it to move to the position of the flux impregnation device 3, and use the flux impregnation device 3 to control the pole ear to complete the casting solder liquid impregnation process;
