DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 and Figure 5The present embodiment proposes a hardware lock assembly machine which is easy to position, comprising a base frame 1, a top frame 2 is fixedly installed on both sides of the top of the base frame 1, and the inner walls of both ends of the base frame 1 and the top frame 2 are rotatably connected with conveying wheels 3, and the outer sides of the conveying wheels 3 are respectively sleeved with a first conveying belt 11 and a second conveying belt 21, and the tops of the first conveying belt 11 and the second conveying belt 21 are provided with a material tray 4 for placing locks, and a moving component 5 for moving the empty material tray 4 is fixedly installed on the inner wall of one end of the top frame 2, an outer frame 6 is fixedly installed on the outer side of the top frame 2, and a lifting seat 7 is slidably connected to the inner side wall of the outer frame 6, fixed racks 71 are fixedly installed on both sides of the lifting seat 7, and a mechanical arm 72 for assembling locks is fixedly installed at one end of the lifting seat 7, and a driving component 8 for driving the lifting seat 7 to rise and fall is provided inside the outer frame 6, and the conveying wheels 3 at the top frame 2 and the base frame 1 are synchronously driven, so that the material trays 4 on the first conveying belt 11 and the second conveying belt 21 can move at the same speed and at the same time. The transmission is in the direction of rotation, and the parts on the two material trays 4 can be placed in different positions when they are required to be assembled. When the material tray 4 moves to be separated from the first conveyor belt 11 and the second conveyor belt 21, and is directly below the mechanical arm 72, the conveying wheel 3 stops rotating, and the driving component 8 can act on the fixed racks 71 at both ends of the lifting seat 7, so that the lifting seat 7 drives the mechanical arm 72 to lift and slide inside the outer frame 6, so that the mechanical arm 72 can grab the parts inside the material tray 4 directly below the second conveyor belt 21, and then the front end position moving component 5 of the second conveyor belt 21 is used to make the empty material tray 4 below the mechanical arm 72 move toward the front end. At this time, the vacant part of the material tray 4 after moving can facilitate the mechanical arm 72 to move downward again, so that the parts grabbed by the mechanical arm 72 can be continuously moved downward to the position of the material tray 4 on the first conveyor belt 11, so that the grabbed parts can be assembled with the parts on the lower material tray 4, thereby effectively preventing the misalignment of the lock assembly;

[0025] See also Figure 2 , Figure 3 , Figure 4 as well as Figure 5The present embodiment provides a hardware lock assembly machine that is easy to position. The moving assembly 5 includes a moving support plate 51 arranged on the outside of the second conveyor belt 21.

The output end of the moving motor 52 is fixedly connected to the other end of the driven rod 53. When it is necessary to move the empty material tray 4 below the mechanical arm 72 forward, the driven rod 53 can be driven by the moving motor 52, and then the driven rod 53 can be driven by the moving motor 52. Due to the action of the moving wheels 55 and the moving belt 56 on the moving rod 53 and the active rod 54, the moving belt 56 can be transmitted on the top of the moving support plate 51, so as to drive the empty material tray 4 in contact with the top of the moving support plate 51 to move forward, and open the vacant part of the moving support plate 51, so as to facilitate the mechanical arm 72 to drive the parts to continue to move downward for assembly. The driving assembly 8 includes two lifting rotating rods 81 rotatably connected to the inner walls of the two ends of the outer frame 6, and one end of the two lifting rotating rods 81 is fixedly installed with a driving wheel 82, and the outer side of the driving wheel 82 is sleeved with a toothed chain 83, and the outer side of the toothed chain 83 is meshed with the fixed rack 71.

The output end of the servo motor 85 is fixedly connected to the other end of the lifting rod 81. When the lifting seat 7 needs to drive the mechanical arm 72 to move up and down inside the outer frame 6, the servo motor 85 can drive the lifting rod 81 to rotate, and through the relative action of the linkage gear 84, the lifting rods 81 on both sides of the lifting seat 7 can drive the toothed chain 83 to perform relative reverse transmission, so that the toothed chain 83 acts on the fixed rack 71 of the lifting seat 7, and then drives the mechanical arm 72 to move up and down. A guide support plate 12 is provided on the outer side of the first conveyor belt 11, and the bottom end of the guide support plate 12 is fixedly connected to the inner wall of one end of the bottom frame 1. After the material tray 4 is assembled, the first conveyor belt 11 continues to drive, and the guide support plate 12 is used to assist the assembled material tray 4 The function of assisting placement is that a driving rod 31 is fixedly installed at one end of the two conveying wheels 3, and a linkage wheel 32 is fixedly installed at the other end of the driving rod 31. A linkage belt 33 is sleeved on the outer side of the linkage wheel 32.
