[0039] The following will be combined with the drawings in 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 in 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.

[0040] See also Figure 1-6 In an embodiment of the utility model, an arrangement machine for precision screw feeding includes a vibrating tray 1, and the vibrating tray 1 for precision screw feeding has an arrangement groove 2 in the middle; the arrangement groove 2 is located in the middle position of the vibrating tray 1, and when vibrating, the screws can be quickly vibrated and arranged in the arrangement groove 2.

[0041] A screw transmission assembly 4 for transmitting precision screws is arranged below the arrangement slot 2. The screw transmission assembly 4 has two rows of transmission wheels 41. A transmission belt 42 is arranged outside each row of transmission wheels 41.

[0042] The two rows of transmission wheels 41 are meshed and driven by two mutually meshing gears 43, and a motor 44 is installed under one of the gears 43, and the motor 44 is fixed under the vibrating material tray 1 through a motor bracket 45; a vibrating motor 6 is provided under the vibrating material tray 1. The vibrating motor 6 is fixed on a hanger 5; the upper end of the hanger 5 is fixed to the vibrating material tray 1.

[0043] By adopting the above technical solution, when in use, the vibration motor 6 is turned on, and the vibration tray 1 is vibrated with the cooperation of the hanger 5. At this time, the screws scattered on the vibration tray 1 will constantly change their positions on the vibration tray 1. When the screws are moved to the arrangement slot 2, the diameter of the tail end thereof is smaller than the width of the arrangement slot 2, so that they fall into the arrangement slot 2, and the top of the screw is larger than the diameter of the arrangement slot 2, so that the screws can be in a vertical state.

[0044] The motor 44, in cooperation with the two gears 43 meshing with each other, causes the conveyor belts 42 outside the two rows of conveyor wheels 41 to rotate, and under the clamping transmission of the two conveyor belts 42, the arrangement and loading of the screws can be gradually realized.

[0045] In addition, it should be noted that: precision screws are referred to as small screws, which have a conical tip. In the initial stage when the screw falls into the arrangement groove 2, it is in an inclined state. At this time, only the tip of the screw can enter between the two conveyor belts 42, but with the rotation transmission of the two conveyor belts 42, and the conveyor belts 42 also have a certain elasticity; therefore, the main part of the screw gradually enters between the two conveyor belts 42, thereby realizing the transmission of the screw.

[0046] In this embodiment, a material baffle plate 3 is provided inside the vibrating material tray 1 . The material baffle plate 3 is L-shaped, with one end fixed to the vibrating material tray 1 and the other end inclinedly disposed on the arrangement slot 2 .

[0047] By adopting the above technical solution, the blocking plate 3 can block the screws on the vibrating material tray 1, thereby preventing the screws that have not entered the arrangement groove 2 from being transmitted out.

[0048] In this embodiment, one end of the two rows of transmission wheels 41 protrudes to the outside of the vibrating material tray 1 , and the end is connected to the vibrating material tray 1 through a connecting plate 11 .

[0049] By adopting the above technical solution, one end of the two rows of transmission wheels 41 is extended to the outside of the vibrating material tray 1 to facilitate the screws to be arranged and enter the next process, or be taken by the user.

[0050] In this embodiment, each row of transmission wheels 41 includes a plurality of rotating wheels, and the rotating wheels are connected to the vibrating material tray 1 or the connecting plate 11 through seat bearings.

[0051] In this embodiment, positioning tubes 9 are provided at the four corners of the bottom of the vibrating material tray 1 , and a spring 7 is sleeved in the positioning tube 9 . The lower end of the spring 7 is sleeved in the positioning tube 9 fixed above the bottom plate 10 .

[0052] Specifically, each spring 7 is sleeved with a rubber column 8; two ends of the rubber column 8 are respectively fixed to the vibration material tray 1 and the bottom plate 10.

[0053] By adopting the above technical solution, the setting of the spring 7 improves the degree of freedom of the vibration tray 1 during vibration, and can make the screw have a better vibration effect in the vibration tray 1. The setting of the rubber column 8 improves the overall stability of the equipment while ensuring the vibration effect of the vibration tray 1, and ensures that there is sufficient support strength to meet the installation and vibration of the vibration motor 6.

[0054] The working principle of the utility model is as follows: when in use, the vibration motor 6 is turned on, and the vibration tray 1 is vibrated with the cooperation of the hanger 5. At this time, the screws scattered on the vibration tray 1 will constantly change positions on the vibration tray 1. When the screws are displaced to the arrangement slot 2, the diameter of their tail ends is smaller than the width of the arrangement slot 2, so that they fall into the arrangement slot 2. In the initial stage when the screws fall into the arrangement slot 2, they are in an inclined state. At this time, only the tip of the screw can enter between the two conveyor belts 42, but with the rotation transmission of the two conveyor belts 42, and the conveyor belts 42 also have a certain elasticity; therefore, the main body of the screw gradually enters between the two conveyor belts 42, and the top of the screw is larger than the diameter of the arrangement slot 2, so that the screw can be in a vertical state.

[0055] Protruding one end of the two rows of transmission wheels 41 to the outside of the vibrating material tray 1 is convenient for the screws to be arranged and enter the next process, or to be taken by the user.
