DETAILED DESCRIPTION

[0029] 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.

When in use, one paste brushing mechanism 2 is used to brush paste on one opposite side of the plate on the plate conveying mechanism 1, and then the plate on the plate conveying mechanism 1 is horizontally rotated 90° by the plate direction adjustment mechanism 3, and finally the other opposite side of the plate on the plate conveying mechanism 1 is brushed with paste by another paste brushing mechanism 2, so as to realize the process of brushing paste on the position on the plate that does not need to be coated with paste, which not only effectively improves the efficiency of brushing paste on the plate, but also reduces the labor intensity of workers, and also avoids the problem of lead powder being easily inhaled due to manual brushing of paste.

[0032] Embodiment 2:

[0033] Based on Example 1, Figure 2-4 As shown, the plate conveying mechanism 1 includes a pair of beams 101 arranged side by side; a pair of rollers 102 are connected to each other in a side-by-side rotation manner between the two beams 101; one end of a roller 102 is coaxially fixed to the output shaft of a first servo motor 103; the first servo motor 103 is bolted to a beam 101; the two rollers 102 are connected to each other through a conveyor belt 104; a plurality of stoppers 105 are connected to the outer surface of the conveyor belt 104 in side by side; the stoppers 105 include a baffle 1051 parallel to the working surface of the conveyor belt 104 and a stopper 1051 riveted horizontally to the outer surface of the conveyor belt 104 The support bar 1052 is arranged on the roller 102; the length direction of the support bar 1052 is parallel to the axial direction of the roller 102; an edge of the baffle 1051 is connected to the support bar 1052 through an elastic sheet 1053 with a U-shaped structure; the two ends of the elastic sheet 1053 are respectively connected to the support bar 1052 and the baffle 1051, and the middle section of the elastic sheet 1053 is away from the conveyor belt 104; a plate limiting space is formed between the baffle 1051 and the conveyor belt 104; a conventional silicone sheet 1054 in the field is fixedly attached to a surface of the baffle 1051 close to the conveyor belt 104. When in use, the electrode plate is horizontally set in the electrode plate limiting space formed between the baffle 1051 and the conveyor belt 104, and the elastic properties of the elastic sheet 1053 are used to achieve stable placement of the electrode plate, and a silicone sheet 1054 is set between the electrode plate and the baffle 1051 to reduce the wear on the electrode plate, and then the first servo motor 103 is used to drive the roller 102 to rotate, prompting the conveyor belt 104 to transport the electrode plate, and the electrode plate limited by the baffle 1051 is located on the side of the support bar 1052 connected to the baffle 1051 close to the conveyor belt 104, so that the electrode plate passes through a paste brushing mechanism 2, a plate adjustment mechanism 3 and another paste brushing mechanism 2 in turn, effectively ensuring the paste brushing efficiency of the electrode plate.

[0034] Among them Figure 4 As shown, a plate positioning mechanism 4 is installed at the input end of the plate conveying mechanism 1; the plate positioning mechanism 4 includes a pair of first supports 401 respectively connected to the two beams 101 by vertical bolts; the upper ends of the two first supports 401 are horizontally bolted to the first cylinders 402; the output ends of the two first cylinders 402 are arranged in a direction perpendicular to the length direction of the beam 101; the output ends of the two first cylinders 402 are bolted to the positioning strips 403 parallel to the beam 101; a plate position correction space is formed between the two positioning strips 403. When in use, after the plate is placed in the plate limiting space formed between the baffle 1051 and the conveyor belt 104, the two first cylinders 402 drive the two positioning strips 403 to approach each other, so as to adjust the position of the plate and make the distance between the plate and the two positioning strips 403 equal, which can effectively ensure the paste brushing effect on the plate.

[0035] Embodiment three:

[0036] Based on Example 2, Figure 5-8 As shown, the paste brushing mechanism 2 includes a protective box 201 bolted to two cross beams 101; an opposite side wall of the protective box 201 is provided with an inlet and outlet window 202 of a rectangular structure; the upper section of the conveyor belt 104 is inserted in the inlet and outlet window 202; the other opposite side walls of the protective box 201 are connected by a load-bearing slat 203, and the two ends of the load-bearing slat 203 are respectively bolted to the other opposite side wall of the protective box 201; the load-bearing slat 203 is arranged above the conveyor belt 104; a pair of rotating shafts 204 are vertically rotatably connected to the load-bearing slat 203; the two rotating shafts 204 are respectively arranged on opposite sides of the conveyor belt 104; the two rotating shafts 204 turn in opposite directions; the lower ends of the two rotating shafts 204 are coaxially fixed with conventional roller brushes 205 in the field; the top wall of the protective box 201 is provided with a rectangular structure accommodating window 209; a transmission shaft 210 is horizontally arranged above the bearing slat 203; a pair of mounting blocks 211 are rotatably connected to the transmission shaft 210 in parallel; the two mounting blocks 211 are bolted to the upper surface of the bearing slat 203; the two ends of the transmission shaft 210 are keyed to the first bevel gear 212; the two first bevel gears 212 are horizontally meshed with the second bevel gear 213; the two second bevel gears 213 are keyed to the upper ends of the two rotating shafts 204 respectively; the transmission shaft 210 is keyed to the first pulley 214; the first pulley 214 is connected to the second pulley 215 through a synchronous belt drive, and the synchronous belt is interspersed in the accommodating window 209; the second pulley 215 is keyed to the output shaft of a second servo motor 216; the second servo motor 216 is bolted to the top wall of the protective box 201. During use, after the pole plate is driven between the two roller brushes 205, the second servo motor 216 drives the transmission shaft 210 to rotate via the second pulley 215 and the first pulley 214, prompting the transmission shaft 210 to drive the two roller brushes 205 to rotate synchronously in the opposite direction via the first bevel gear 212, the second bevel gear 213 and the rotating shaft 204, and the rotation direction of the roller brush 205 is opposite to the conveying direction of the pole plate, thereby realizing the paste brushing treatment of the pole plate, effectively ensuring the paste brushing efficiency of the pole plate.

[0037] It should be noted that, since the electrode plate has a rectangular structure, that is, the length of one relative side of the electrode plate is greater than the length of the other relative side, the distance between the two roller brushes 205 of one paste brushing mechanism 2 is slightly smaller than the length of one relative side of the electrode plate, while the distance between the two roller brushes 205 of the other paste brushing mechanism 2 is slightly smaller than the length of the other relative side of the electrode plate, that is, the distances between the two roller brushes 205 of the two paste brushing mechanisms 2 are inconsistent, thereby effectively ensuring the paste brushing effect of the roller brush 205 on the electrode plate.

[0038] Embodiment 4:

[0039] Based on Example 3 Figure 9-11 As shown, the plate adjustment mechanism 3 includes a pair of second supports 301 respectively connected to the two beams 101 by vertical bolts; the upper ends of the two second supports 301 are vertically bolted to the second cylinders 302; the output ends of the two second cylinders 302 are connected through a lifting seat 303, and the output end of the second cylinder 302 is bolted to the lifting seat 303; the lifting seat 303 is horizontally bolted to the third cylinder 304; the extension direction of the output end of the third cylinder 304 is arranged parallel to the length direction of the beam 101; the output end of the third cylinder 304 is bolted to the movable seat 305; the movable seat 305 is horizontally bolted to the rotating cylinder 306; the output end of the rotating cylinder 306 is bolted to the vacuum seat 307; the lower surface of the vacuum seat 307 is vertically connected with a plurality of conventional negative pressure suction nozzles 308 in the field. When in use, the negative pressure suction nozzle 308 is placed in a negative pressure state through the vacuum seat 307. When the electrode plate is transported to the bottom of the negative pressure suction nozzle 308, the second cylinder 302 quickly drives the negative pressure suction nozzle 308 to move downward, causing the electrode plate to be sucked by the negative pressure suction nozzle 308, and then the third cylinder 304 drives the negative pressure suction nozzle 308 to move quickly toward the output end of the conveyor belt 104, causing the electrode plate to be driven to leave a certain gap between it and the support bar 1052, and the electrode plate is still pressed by the baffle 1051 at this time, and then the rotating cylinder 306 is used to drive the electrode plate to rotate horizontally 90° quickly through the negative pressure suction nozzle 308, and finally the negative pressure suction nozzle 308 is reset after losing the negative pressure state, thereby realizing the adjustment of the electrode plate, which can ensure that the four sides of the electrode plate are brushed with paste.
