Description

Technical Field

[0001] The utility model relates to the technical field related to battery production, in particular to a lead-acid battery grid burr cleaning device. Background Art

[0002] The production methods of battery grid mainly include casting and stretching. Among them, casting is to pour the heated and molten lead alloy into the grid mold under the action of gravity, and then cool it into shape and then process it. Stretched grid is to make a specified rectangular hole on a lead strip of a certain width on a punch press, and then stretch it and form it.

[0003] The cast battery grid ribs often have certain burrs during the manufacturing process. The burrs attached to the grid surface are difficult to clean. The burrs of the grid are easy to cause the back of the lead paste to be squeezed out when the plate is coated, resulting in a lack of paste after the plate is coated, the grid ribs are exposed, and the double-sided coating effect of the plate is poor. During the cycle of the battery, especially the positive plate, it is more likely to cause the active material to fall off, affecting the performance of the battery; larger grid burrs may also cause the plate to jam during the coating process. The grid burrs are carried into the plate and may even puncture the partition and cause an internal short circuit in the battery, seriously affecting the quality of the battery. Such a grid with burrs cannot be used directly for plate coating, and the grid needs to be cleaned of burrs. Utility Model Content

[0004] The utility model aims to provide a lead-acid battery grid burr cleaning device, which can cut off the grid burr, ensure smooth plate coating, and prevent the burr from being carried into the plate and even puncturing the partition to cause internal short circuit of the battery.

[0005] To this end, the technical solution adopted by the utility model is: a lead-acid battery grid burr cleaning device, including a cleaning component, a feed conveyor belt arranged at the front end of the cleaning component and a discharge conveyor belt arranged at the rear end of the cleaning component, the cleaning component including a cutting structure and a fixed base arranged at an angle with a higher front and a lower rear, the cutting structure including a cutting plate arranged above the fixed base and parallel to the fixed base and a cylinder for lifting the cutting plate, the front and rear ends of the cutting plate are horizontally provided with cutting knives with blades facing downwards that are perpendicular to the cutting plate, the fixed base is provided with cutting grooves corresponding to the cutting knives, the left and right sides of the cutting plate are provided with vertically extending slide rails near the rear side of the cutting knife located at the front end, the slide rails are slidably connected with fixed columns, the fixed columns are in the shape of "[", and the fixed columns on both sides The openings are arranged relatively to each other, and a slot for inserting a fixing column is opened on the fixing base, and a spring is arranged in the slot. When the cutting plate is at the uppermost position, at least a part of the inwardly extending part of the fixing column at the lower end is located above the notch of the slot. When the cutting plate moves downward, the fixing column remains in a constant position relative to the fixed base under the action of the spring until the fixing column moves to the topmost end of the slide rail. At this time, the cutting plate continues to move downward, driving the fixing column to move downward until the inwardly extending part of the lowest end of the fixing column completely slides into the slide groove. At this time, the cutting knife can cut the burr of the plate grid on the fixed base. After the cutting is completed, the cutting plate moves upward, and the cutting knife leaves the cutting groove first. At this time, the fixing column stays in the slot, and the plate grid has no support at this time, and slides obliquely downward into the discharge conveyor belt.

[0006] Further preferably, at least two groups of feed rollers are arranged between the end of the feed conveyor belt and the cleaning assembly, and at least two groups of discharge rollers are arranged between the front end of the discharge conveyor belt and the cleaning assembly.

[0007] Further preferably, each set of discharge rollers and feed rollers includes two rotating rollers arranged one above the other, and cleaning brushes are evenly spaced on the rotating rollers. The cleaning brushes can clean the burrs on the surface of the grid and the fine particles adsorbed on the grid, so as to prevent the machine from getting stuck during the grid paste coating process and affect the quality of the battery.

[0008] More preferably, longitudinal columns for stacking the grids are arranged on the left and right sides of the end of the discharge conveyor belt. After the burrs of the grids are cleaned, they slide along the longitudinal columns for a certain distance to facilitate the collection of the grids.

[0009] More preferably, a recycling box is provided below the fixed base to collect waste materials in the process of cleaning the burrs of the grid and to be melted again to make the grid, thereby saving resources.

[0010] The beneficial effects of the utility model are as follows: the grid enters the fixed base through the feed conveyor belt, and the inwardly extending part of the lower end of the fixed column is higher than the upper surface of the fixed base, which just clamps the pole ear of the grid, thereby limiting the grid on the fixed base. At this time, the cylinder drives the cutting plate to move downward. In the process of moving downward, first, the fixed column is immovable relative to the fixed base due to the action of the spring. When the fixed column slides to the top of the slide rail, the cutting plate continues to move downward, and the fixed column is inserted downward into the slot until the cutting knife contacts the burrs on both sides of the grid to cut off the burrs. After the burrs are cut off, the cutting plate moves upward, first driving the movement of the cutting knife. At this time, the extending part in the fixed column is completely inserted downward into the slot, and the pole ear of the grid has no support. Due to the action of gravity, the grid moves obliquely downward and enters the discharge conveyor belt to complete the cleaning of the burrs of the grid. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1-3 As shown, a lead-acid battery grid burr cleaning device comprises a cleaning component, a feed conveyor belt 1 arranged at the front end of the cleaning component and a discharge conveyor belt 2 arranged at the rear end of the cleaning component, the cleaning component comprises a cutting structure and a fixed base 3 which is inclined and arranged with a higher front and a lower rear, the cutting structure comprises a cutting plate 4 which is arranged above the fixed base 3 and parallel to the fixed base 3 and a cylinder for lifting the cutting plate 4, the front and rear ends of the cutting plate 4 are both laterally provided with cutting knives 5 which are perpendicular to the cutting plate 4 and have blades facing downwards, the fixed base 3 is provided with cutting grooves corresponding to the cutting knives 5, the left and right sides of the cutting plate 4 are provided with vertically extending slide rails 7 near the rear side of the cutting knife 5 located at the front end, a fixed column 6 is slidably connected to the slide rail 7, the fixed column 6 is in a "[" shape, the openings of the fixed columns 6 on both sides are arranged opposite to each other, the fixed base 3 is provided with a slot for inserting the fixed column 6, and a spring is arranged in the slot.

[0016] When the cutting plate 4 is moved downward, the fixing column 6 remains in a position relative to the fixing base 3 until the fixing column 6 moves to the top of the slide rail 7. At this time, the cutting plate 4 continues to move downward, driving the fixing column 6 to move downward until the inwardly extending portion of the lowest end of the fixing column 6 completely slides into the slide groove. At this time, the cutting knife 5 can cut the burr of the cutting plate on the fixing base 3. After the cutting is completed, the cutting plate 4 moves upward, and the cutting knife 5 leaves the cutting groove first. At this time, the lower end extending portion of the fixing column 6 has slid into the slide groove, and the fixing column 6 stays in the slot. The ear is not blocked, and the cutting plate has no support, so it slides obliquely downward into the discharging conveyor 2.

[0017] At least two groups of feed rollers are arranged between the end of the feed conveyor belt 1 and the cleaning assembly, and at least two groups of discharge rollers are arranged between the front end of the discharge conveyor belt 2 and the cleaning assembly.

[0018] Each set of discharging rollers and feeding rollers includes two rotating rollers 8 arranged one above the other, and cleaning brushes are evenly spaced on the rotating rollers 8. The cleaning brushes can clean the burrs on the surface of the grid and the fine particles adsorbed on the grid, preventing the machine from getting stuck during the grid paste coating process, which affects the quality of the battery.

[0019] The left and right sides of the end of the discharge conveyor belt 2 are provided with longitudinal columns 9 for stacking the grid. The longitudinal columns 9 are provided, and after the burrs of the grid are cleaned, they slide along the longitudinal columns 9 for a certain distance, so as to facilitate the collection of the grid.

[0020] A recycling box 10 is provided below the fixed base 3. The recycling box 10 is provided to collect waste materials in the process of cleaning the burrs of the grid, and can be melted again to make the grid, thereby saving resources.

[0021] The grid enters the fixed base 3 through the feed conveyor belt 1, and the inward extending part of the lower end of the fixed column 6 is higher than the upper surface of the fixed base 3, which just clamps the pole ear of the grid, thereby limiting the grid on the fixed base 3. At this time, the cylinder drives the cutting plate 4 to move downward. In the process of moving downward, the fixed column 6 first does not move relative to the fixed base 3 due to the action of the spring. When the fixed column 6 slides to the top of the slide rail 7, the cutting plate 4 continues to move downward, and the fixed column 6 is inserted downward into the slot until the cutting knife 5 contacts the burrs on both sides of the grid to cut off the burrs. After the burrs are cut off, the cutting plate 4 moves upward, first driving the movement of the cutting knife 5. At this time, the extending part of the fixed column 6 is completely inserted downward into the slot, and the pole ear of the grid has no support. Due to the action of gravity, the grid moves obliquely downward and enters the discharge conveyor belt 2 to complete the cleaning of the burrs of the grid.
