Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery electrode plate production technology, specifically to a lead-acid battery electrode plate coating device. Background Technology

[0002] Lead-acid batteries primarily use lead and its oxides as electrodes, and sulfuric acid as the electrolyte. The battery mainly consists of positive and negative plates, electrolyte, separators, battery case, battery cover, terminals, and filler caps. The plates are a crucial component of the battery. Plate manufacturing typically involves coating a grid plate, then shaping and curing it. After coating, the outer surface of the lead paste on the grid is not smooth, and lead paste easily adheres to the tabs. After curing, burrs easily form on the outer surface of the lead paste on the grid. The sharp edges of these burrs may scratch adjacent separators or plates during battery assembly, increasing the risk of internal short circuits. Burrs also cause uneven current distribution, increasing contact resistance, affecting battery charging and discharging efficiency, and generating additional heat, thus impacting plate quality. Lead paste adhering to the tabs also affects subsequent tab welding.

[0003] Patent document CN204583732U discloses a brush for cleaning excess paste in the coating process of battery plates. It includes a coating machine receiving device and two brushes mounted on the receiving device. The brushes are symmetrically arranged on both sides of the receiving device, with the bristles facing upwards and both brushes on the same plane. This technical solution can clean excess paste from the lower edge of large plates; however, it cannot smooth the edges of the lead paste on the grid. After the plates cure, burrs easily form on the outer edge of the lead paste, affecting quality. Utility Model Content

[0004] The main purpose of this utility model is to provide a lead-acid battery plate coating device that can clean the lead paste adhering to the tabs and smooth and trim the edges of the lead paste on the grid.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A lead-acid battery electrode coating device includes a frame. Two coating mechanisms are symmetrically arranged vertically on one side of the frame. A roller pressing mechanism is installed on the frame on one side of the coating mechanism. Two support rollers are rotatably arranged on the frame on the other side of the roller pressing mechanism. An outer edge-applying mechanism, an inner edge-applying mechanism, and a cleaning mechanism are arranged sequentially between the two support rollers. The outer edge-applying mechanism includes two fixed plates symmetrically arranged front and back. The fixed plates are fixed to the frame. Two support plates are arranged between the two fixed plates. The support plates are inverted L-shaped. A smooth rod is slidably arranged on the fixed plate and fixedly connected to the support plate. An adjusting bolt is threadedly connected to the fixed plate and rotatably connected to the support plate. A double-ended screw is rotatably arranged at the upper end of the support plate. A sizing block is threadedly connected to the threaded ends on both sides of the double-ended screw. The sizing block is slidably connected to the support plate. A first inclined surface is machined on both the left and right ends of the sizing block and a second inclined surface is machined on both the left and right ends of the sizing block facing the center of the frame.

[0007] Specifically, the guide rod and the adjusting bolt are parallel, the guide rod is set longitudinally, and the double-ended screw is set vertically.

[0008] Specifically, the inner edge-finishing mechanism includes two upright plates arranged symmetrically front to back. The upright plates are fixed to the frame. Each upright plate is provided with two inner edge-finishing units arranged symmetrically from top to bottom. Each inner edge-finishing unit includes a trowel, on which multiple sliding rods are fixed. The sliding rods pass through one side of the upright plate and are slidably connected to the upright plate. The end of the sliding rod passing through the upright plate is fixedly connected to a connecting plate. The connecting plate is connected to a positioning bolt by a screw, and the positioning bolt is rotatably connected to the upright plate.

[0009] Specifically, the upper end of the upper trowel is inclined towards the vertical plate on one side, and the lower end of the lower trowel is inclined towards the vertical plate on one side. The end of the trowel facing the material receiving side of the grid is machined with a rounded corner, which is close to the pole lug of the grid. The slide rod is set longitudinally and is parallel to the positioning bolt.

[0010] Specifically, the cleaning mechanism includes two vertical plates arranged symmetrically front to back, and two rotating rods rotatably arranged between the two vertical plates. The two rotating rods are arranged symmetrically up and down, and each rotating rod is concentrically fixed with a roller brush. Two motors are fixed on any one of the vertical plates, and the output shafts of the two motors are respectively connected to the two rotating rods. The two roller brushes can respectively brush the upper and lower sides of the electrode tabs of the grid.

[0011] Specifically, the roller pressing mechanism includes a support roller and a pressure roller rotatably mounted on the frame. The support roller and pressure roller are positioned vertically, and a grid coated with lead paste passes between the support roller and pressure roller and is squeezed by the support roller and pressure roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The outer edge smoothing mechanism adjusts the spacing of the smoothing blocks through double-ended screws. Combined with the guiding effect of the first inclined surface and the gathering effect of the second inclined surface, it can simultaneously smooth and compact the outer edge of the lead paste, reducing burrs after curing. Its adjustment bolt and smooth rod linkage design makes it easy to adapt to different specifications of grids and ensure consistent edge smoothing accuracy.

[0014] 2. The trowel of the inner edge smoothing unit is arranged at an angle. With the fine adjustment of the slide bar and positioning bolt, it forms directional pressure when smoothing the inner edge of the lead paste, which enhances the density of the lead paste. The rounded corner design of the end of the trowel avoids scratching the electrode tabs, and at the same time accurately positions the area near the electrode tabs to avoid lead paste residue on the inner edge.

[0015] 3. The cleaning mechanism uses symmetrical upper and lower rollers to rotate at high speed, simultaneously removing lead paste residue from both sides of the electrode tabs; the active cleaning mode of the motor-driven rollers is more efficient than the traditional passive contact, avoiding lead paste adhering to the electrode tabs and affecting the subsequent casting and welding quality, and reducing the risk of short circuits during battery assembly.

[0016] 4. The outer edge finishing, inner edge finishing, and cleaning mechanisms are independently set between two support rollers, forming a continuous processing procedure; the adjustment components of each mechanism support rapid adjustment to meet the production needs of different lead paste thicknesses and grid sizes, and have strong compatibility.

[0017] 5. This device integrates coating, rolling, edge trimming and cleaning functions. The entire coating process can be completed in a single pass through the grid, avoiding lead paste deformation or contamination caused by multiple handling, and significantly improving the yield and efficiency of electrode production.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The coating plate 10 used in conjunction with this device consists of two rows of symmetrically arranged grids 10, with the tabs 2 on both the front and rear sides of the grids 10 fixedly connected. During coating, under the obstruction of the paste baffle, the upper and lower ends of the grids 10 on both the front and rear sides of the tabs 2 are coated with lead paste 11. The edge of the lead paste 11 near the tabs 2 is the inner edge 12, and the edge of the lead paste 11 away from the tabs 2 is the outer edge 13.

[0026] Example 1: Refer to Figures 1-5 As shown, a lead-acid battery electrode plate coating device includes a frame 1. Two coating mechanisms 3 are installed on one side of the frame 1, arranged symmetrically. A roller pressing mechanism is installed on the frame 1 on one side of the coating mechanism 3. Two support rollers 6 are rotatably arranged on the frame 1 on the side of the roller pressing mechanism. An outer edge wiping mechanism 7, an inner edge wiping mechanism 8, and a cleaning mechanism 9 are arranged sequentially between the two support rollers 6.

[0027] The roller pressing mechanism includes a support roller 4 and a pressure roller 5 rotatably mounted on the frame 1. The pressure roller 5 and the support roller 4 are arranged vertically. The grid 10 coated with lead paste 11 passes between the support roller 4 and the pressure roller 5 and is squeezed by the support roller 4 and the pressure roller 5.

[0028] The outer edge finishing mechanism 7 includes two symmetrically arranged fixed plates 701, which are fixed to the frame 1. Two support plates 702 are arranged between the two fixed plates 701, each in an inverted L-shape. A smooth rod 705 is slidably mounted on each fixed plate 701 and is fixedly connected to the support plate 702. An adjusting bolt 708 is threaded onto each fixed plate 701 and is rotatably connected to the support plate 702. The smooth rod 705 and the adjusting bolt 708 are parallel and longitudinally arranged. A double-ended screw 703 is rotatably mounted on the upper end of each support plate 702. The double-ended screw 703 is vertically arranged, and finishing blocks 704 are threaded onto the threaded ends on both sides of the double-ended screw 703. The finishing blocks 704 are slidably connected to the support plate 702. A first inclined surface 706 is machined on both the left and right ends of the finishing block 704, and a second inclined surface 707 is machined on both the left and right ends of the finishing block 704 facing the center of the frame 1.

[0029] After the lead paste 11 is applied to the grid 10 by the coating mechanism 3, the front part of the grid 10 is located between the two front trowel blocks 704, and the rear part of the grid 10 is located between the two rear trowel blocks 704. Rotating the double-ended screw 703 adjusts the distance between the two trowel blocks 704, so that the lower end of the upper trowel block 704 contacts the upper end of the grid 10, and the upper end of the lower trowel block 704 contacts the lower end of the grid 10. Rotating the adjusting bolt 708 adjusts the distance between the two support plates 702. When the grid 10 moves between the trowel blocks 704, the end face of the trowel blocks 704 facing the center of the frame 1 can smooth the outer edge 13 of the lead paste 11. By setting the second inclined surface 707, the lead paste 11 dispersed near the outer edge 13 can be gathered, increasing the density of the lead paste 11 on the outer edge 13.

[0030] The inner edge finishing mechanism 8 includes two upright plates 801 arranged symmetrically front to back. The upright plates 801 are fixed on the frame 1, and each upright plate 801 is provided with two inner edge finishing units arranged symmetrically from top to bottom.

[0031] The inner edge finishing unit includes a finishing plate 805, on which multiple sliding rods 802 are fixed. The sliding rods 802 pass through a vertical plate 801 on one side of the finishing plate 805 and are slidably connected to the vertical plate 801. The end of the sliding rod 802 passing through the vertical plate 801 is fixedly connected to a connecting plate 803. A positioning bolt 804 is screwed onto the connecting plate 803 and is rotatably connected to the vertical plate 801.

[0032] The upper end of the upper trowel 805 is inclined toward the vertical plate 801 on one side, and the lower end of the lower trowel 805 is inclined toward the vertical plate 801 on one side. The slide rod 802 is set longitudinally and is parallel to the positioning bolt 804.

[0033] The tab 2 of the grid 10 passes between the upper and lower squeegees 805. By rotating the positioning bolt 804 and adjusting the position of the squeegee 805 via the slide rod 802, the squeegee 805 can smooth the inner edge 12 of the lead paste 11 on one side when the grid 10 moves. Since the upper end of the upper squeegee 805 is inclined towards the vertical plate 801 on one side, and the lower end of the lower squeegee 805 is inclined towards the vertical plate 801 on one side, the squeegee 805 can compress the inner edge 12 of the lead paste 11 during the smoothing process, thus compacting the inner edge 12 of the lead paste 11.

[0034] The cleaning mechanism 9 includes two vertical plates 901 arranged symmetrically front to back, and two rotating rods 902 rotatably arranged between the two vertical plates 901. The two rotating rods 902 are arranged symmetrically up and down, and a roller brush 903 is concentrically fixed on each of the rotating rods 902. Two motors 904 are fixed on any one of the vertical plates 901, and the output shafts of the two motors 904 are respectively connected to the two rotating rods 902. The two roller brushes 903 can respectively brush the upper and lower sides of the tab 2 part of the grid 10.

[0035] When the two motors 904 drive the two rotating rods 902 to rotate, the two roller brushes 903 rotate synchronously. The two rotating roller brushes 903 can brush the upper and lower sides of the electrode tab 2, which can remove the lead paste 11 adhering to the upper and lower ends of the electrode tab 2, and ensure the quality of subsequent electrode tab 2 casting and welding.

[0036] Example 2: Based on Example 1, referring to... Figure 4 As shown, the end of the trowel 805 facing the material receiving side of the grid 10 is machined with a rounded corner, which is close to the grid 10.

[0037] The squeegee 805 has rounded corners, which can prevent the squeegee 805 from getting stuck with the tabs 2 of the grid 10 when the grid 10 moves.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
