Description

Technical Field

[0001] The invention relates to the technical field of battery plate processing, in particular to a lead-acid battery plate coating device. Background Art

[0002] Lead-acid battery plate coating is an important link in the production process of lead-acid batteries, which usually includes material preparation, plate coating, plate curing, plate separation and packaging and other related processes. The plate coating process is the process of applying lead paste on the grid to form a paste-coated plate. In the process, the specified weight of lead paste is evenly filled in the grid grid to make the lead paste and the grid well combined.

[0003] After searching, a Chinese patent (publication number: CN213700592U) discloses a lead-acid battery plate coating device, which includes a coating box and an insulation board. The insulation board is fixed on the inner wall of the coating box. The insulation board divides the interior of the coating box into a drying chamber and a coating chamber. A drying mechanism is provided inside the drying chamber, and a coating mechanism and a scraping mechanism are provided inside the coating chamber. The coating mechanism is provided on one side of the scraping mechanism. A recovery chamber is provided on one side of the coating box, and the recovery chamber is provided at the bottom of the drying chamber. A recovery mechanism is provided inside the recovery chamber.

[0004] When coating the grid, it is necessary to keep the lead paste on the upper side of the grid with good integrity and thickness to improve product quality, and during processing, it is necessary to prevent excess lead paste from being wasted. Therefore, the present invention proposes a lead-acid battery plate coating device. Summary of the invention

[0005] The object of the present invention is to provide a lead-acid battery plate coating device.

[0006] The technical problem solved by the present invention is: how to improve the integrity and thickness of the lead paste on the grid, and how to prevent the waste of excess lead paste during production.

[0007] The present invention can be implemented by the following technical scheme: A lead-acid battery plate coating device comprises a first conveying unit, a coating assembly is installed on the upper side of the first conveying unit, and a first adjustment cylinder assembly and a second adjustment cylinder assembly are installed in sequence on the side of the first conveying unit along the moving direction, and a feeding assembly is installed on the upper side of the first conveying unit between the first adjustment cylinder assembly and the second adjustment cylinder assembly;

[0008] The output end of the first adjusting cylinder assembly is equipped with a cutting assembly that crosses the first conveying unit, and the output end of the second adjusting cylinder assembly is equipped with a pressing roller assembly that crosses the first conveying unit;

[0009] The grid to be processed passes through the coating assembly, the cutting assembly, the filling assembly and the lower side of the pressing roller assembly from the first conveying unit in sequence. When the grid passes through the coating assembly, the coating assembly applies lead paste to the outer side of the grid and flattens it once;

[0010] When the grid passes through the cutting assembly, the cutting assembly controls the thickness of the lead paste on the outside of the grid and removes and recycles the excess lead paste;

[0011] When the grid passes through the filling assembly, the filling assembly adds lead paste to the outside of the grid in dots, and when passing through the pressing roller assembly, the pressing roller assembly presses the grid and lead paste to the designed thickness.

[0012] A further technical improvement of the present invention is that a second conveying unit is arranged at one end of the first conveying unit facing away from the smear assembly, and the height of the second conveying unit is lower than that of the first conveying unit. After adjacently arranged grids enter the second conveying unit along the first conveying unit, due to the height difference, gaps appear between the grids when they are transferred.

[0013] A further technical improvement of the present invention is that: the cutting assembly comprises a first box connected to the output end of the first adjustment cylinder assembly, a scraper unit is installed on the lower side of the first box, and the scraper unit changes the distance between the scraper unit and the grid based on the first adjustment cylinder assembly, so as to facilitate the removal of lead paste of corresponding thickness on the grid;

[0014] A second conveying unit is installed inside the first box at one end of the first conveying unit, and the second conveying unit is arranged at the lower side of the top of the first conveying unit;

[0015] A first conveying unit is installed on one side of the scraper unit inside the first box, and the bottom of the first conveying unit extends to obliquely below the top of the scraper unit. After the lead paste is taken out from the grid by the scraper unit, it is accumulated on the upper side of the scraper unit and transferred to the first conveying unit as the amount of lead paste increases. The first conveying unit transfers the lead paste to the second conveying unit, and the second conveying unit transports the lead paste away from the first box.

[0016] A further technical improvement of the present invention is that: a driving mechanism is installed inside the first box at a side of the scraper unit facing away from the first conveying unit, and a contact plate is installed at the output end of the driving mechanism;

[0017] The contact plate rotates based on the driving mechanism and periodically passes through one side of the scraper unit to move the lead paste accumulated on the scraper unit to the first conveying unit, thereby facilitating the rapid transfer of the lead paste.

[0018] A further technical improvement of the present invention is that: the feeding assembly comprises a second box connected to the first conveying unit, a raw material box is installed inside the second box, the raw material box is used to store lead paste, and a plurality of discharge heads connected to the raw material box are installed on the lower side of the second box, and the plurality of discharge heads are distributed at a position perpendicular to the moving direction of the first conveying unit;

[0019] After each discharging head is started, the lead paste in the raw material box is discharged;

[0020] A fixing frame is installed on the lower side of the second box body at one side of each discharging head, and an output mechanism is installed inside the second box body;

[0021] A cutting unit is slidably connected inside the fixing frame, and one end of the cutting unit facing away from each discharge head is connected to the output end of the output mechanism;

[0022] After the output mechanism is started, it drives the cutting unit to slide along the fixed frame, and the cutting unit extends to the lower side of each discharge head to cut off the lead paste discharged from each discharge head to prevent it from adhering to the lower side of the discharge head. After the fixed frame moves to the inside of the fixed frame, the lead paste can be separated.

[0023] A further technical improvement of the present invention is that each of the discharge heads is started periodically, and each of the discharge heads is started at least once when each group of grids passes by.

[0024] A further technical improvement of the present invention is that: a visual detection component is installed on the side of the second box body facing the smear component;

[0025] When each grid passes, the visual inspection component divides a plurality of identification area units corresponding to the plurality of grids on the sheet of lead paste based on the uncoated parts of each grid;

[0026] The visual inspection component inspects the surface integrity of each identification area unit, that is, whether there is a concave area on the surface of each corresponding grid;

[0027] When there is a concave area, the discharge head in the axial direction corresponding to the concave area is identified, and the corresponding discharge head is activated a corresponding number of times based on the area and depth of the concave area when the corresponding grid passes by;

[0028] The number of starts is preset based on the amount of lead paste discharged by each discharge head at a time.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention provides a cutting assembly between the coating assembly and the pressing roller assembly, so that the excess lead paste on the upper side of each grid can be removed and recycled before the grid is pressed by the pressing roller assembly, thereby reducing the loss of raw materials.

[0031] In addition, by using the filling component, lead paste can be added to the surface of the grid before it is pressure-coated, thereby avoiding the problem of incomplete filling of lead paste on the surface of the grid, thereby improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS
