DETAILED DESCRIPTION

[0026] The principles and features of the present application are described below in conjunction with the accompanying drawings, in which the examples are used to explain the present application and are not intended to limit the scope of the present application.

[0027] As shown in Figure 1 , Figure 8 A loudspeaker metal screen assembly structure, comprising a conveying table 1, a mounting plate 4, a plurality of loudspeaker positioning grooves are arranged equidistantly on the conveying table 1, and the loudspeaker positioning grooves are used for placing loudspeakers 2. The mounting plate 4 is fixed with a first sliding rail 6, a second sliding rail 13 and a top air cylinder 3. The top air cylinder 3 is located at the top of the mounting plate 4, and a U-shaped frame 9 is installed on the movable shaft of the top air cylinder 3. The first sliding rail 6 and the second sliding rail 13 are parallel to each other, and a hopper 8 is slidably connected to the second sliding rail 13. The hopper 8 is in a cylindrical shape, and the internal cavity of the hopper 8 is through from top to bottom. One side of the U-shaped frame 9 is slidably connected to the first sliding rail 6, and the other side of the U-shaped frame 9 is fixedly connected to the side of the hopper 8. The hopper 8 is used for loading metal screens 12, and the metal screens 12 are stacked in the hopper 8. A circle of V-shaped protrusions 24 is arranged at the edge of the metal screen 12, and the V-shaped protrusions 24 can simultaneously play a positioning and stabilizing role when the metal screens 12 are stacked.

[0028] As shown in Figure 2 , Figure 3 The bottom of the hopper 8 is provided with a discharging module, and the discharging module comprises two groups of discharging units, and the two groups of discharging units are respectively located at the two sides of the bottom of the hopper 8. Each group of discharging units comprises a first discharging air cylinder 18, a second discharging air cylinder 19, a first material blocking air cylinder 20, a third discharging air cylinder 21 and a second material blocking air cylinder 22. The bottom of the hopper 8 is provided with a second through hole 17 and a first through hole 16 on the two sides. The first discharging air cylinder 18, the second discharging air cylinder 19, the first material blocking air cylinder 20, the third discharging air cylinder 21 and the second material blocking air cylinder 22 are arranged in sequence from top to bottom. The movable shafts of the first discharging air cylinder 18, the second discharging air cylinder 19 and the first material blocking air cylinder 20 all pass through the inside of the second through hole 17, and the movable shafts of the third discharging air cylinder 21 and the second material blocking air cylinder 22 all pass through the inside of the first through hole 16. The movable shafts of the first discharging air cylinder 18, the second discharging air cylinder 19 and the third discharging air cylinder 21 are all provided with soft clamps, and the movable shafts of the first material blocking air cylinder 20 and the second material blocking air cylinder 22 are all provided with baffles. The soft clamp on the movable shaft of the third discharging air cylinder 21 is in an "L" shape. The bottom of the hopper 8 is provided with an outer cover 23 on the two sides, and the first discharging air cylinder 18, the second discharging air cylinder 19, the first material blocking air cylinder 20, the third discharging air cylinder 21 and the second material blocking air cylinder 22 are all located in the outer cover 23 and fixed on the outer cover 23.

[0029] When the hopper 8 is discharged, the initial state is that the movable shaft of the first blocking cylinder 20 is in the extended state, and the blocking plate blocks the upper metal mesh cover 12. The movable shafts of the second discharge cylinder 19 and the first blocking cylinder 20 are in the extended state, and the two metal mesh covers 12 at the bottom are clamped by the two groups of second discharge cylinders 19 and first blocking cylinders 20 on the left and right sides, and the soft clamp can avoid damaging the metal mesh cover 12. When discharging, the two second blocking cylinders 22 on the sides act to push the blocking plate on the movable shaft out. At this time, the movable shaft of the third discharge cylinder 21 is in the retracted state, and then the movable shafts of the two second discharge cylinders 19 and the first blocking cylinder 20 are retracted. The bottom metal mesh cover 12 falls on the blocking plate of the movable shaft of the second blocking cylinder 22, the third discharge cylinder 21 acts to clamp it, the movable shaft of the first blocking cylinder 20 is extended, the movable shafts of the first discharge cylinder 18 and the second discharge cylinder 19 are retracted, and the upper metal mesh cover 12 falls on the blocking plate of the movable shaft of the first blocking cylinder 20. The movable shafts of the first discharge cylinder 18 and the second discharge cylinder 19 are extended to clamp the metal mesh cover 12. Thus, the discharging process is realized, that is, a single metal mesh cover 12 is discharged to the blocking plate of the movable shaft of the second blocking cylinder 22.

[0030] The hopper 8 is located on the upper side of the conveying table 1, and the bottom of the mounting plate 4 is provided with a positioning camera 5. When the loudspeaker 2 on the conveying table 1 moves to the lower side of the positioning camera 5, the positioning camera 5 takes a photo and uploads it to the operation module for comparison, so as to calculate how far the loudspeaker 2 is from the center position directly below the hopper 8, and control the conveying system on the conveying table 1 to move forward by the length, so as to ensure that the loudspeaker 2 is located at the center position directly below the hopper 8 and stops after moving to the position. Then the top cylinder 3 acts to push the hopper 8 downward, and in this process, the movable shaft of the second blocking cylinder 22 is retracted, and the blocking plate is moved aside, so as to buckle the metal mesh cover 12 on the loudspeaker 2. Then the third discharge cylinder 21 is retracted, the top cylinder 3 returns to the original position, and the discharging cycle of the next metal mesh cover begins. Then the conveying table 1 conveys the loudspeaker 2 to the dispensing station. The outer side of the hopper 8 is provided with a sensor mounting rack 7, two limit sensors 14 are installed on the sensor mounting rack 7, and a protrusion 15 is arranged on the side of the hopper 8. When the protrusion 15 moves to the position of the limit sensor 14, the signal of the limit sensor 14 changes, so as to control the cylinder to stop. The up-and-down stroke range of the top cylinder 3 can be accurately controlled through the limit sensor 14.

[0031] As Figure 4 - Figure 8As shown, the outer side of the loudspeaker 2 is provided with a ring-shaped loudspeaker frame 10, and a circle of V-shaped grooves 11 is arranged on the loudspeaker frame 10, the cross sections of the V-shaped protrusions 24 and the V-shaped grooves 11 are both "V" shaped, and the V-shaped protrusions 24 are matched with the V-shaped grooves 11. The inclined edges of the cross sections of the V-shaped grooves 11 and the V-shaped protrusions 24 are both concave arcs, and there is a gap between the V-shaped grooves 11 and the V-shaped protrusions 24 after matching, and a plurality of small holes are arranged on the V-shaped protrusions 24 to facilitate the penetration of glue. When dispensing glue, the glue dispensing pen dispenses glue into the V-shaped protrusions 24 of the metal mesh cover 12, and the upper side of the V-shaped protrusions 24 is in a groove shape, so the glue will accumulate inside, and the glue penetrates into the V-shaped grooves 11 through the small holes on the V-shaped protrusions 24, and due to the gap between the V-shaped grooves 11 and the V-shaped protrusions 24 after matching, the glue can be uniformly penetrated therebetween by the siphon effect, thereby increasing the bonding surface of the glue and ensuring the firmness of the connection between the two.
