Description

Carrier suction and blow cycle automatic screw locking machine

Technical field

The invention relates to the technical field of automatic screw loading equipment, and in particular to an automatic screw locking machine with a suction and blow cycle for a carrier.

Background technique

Screws are essential hardware standard parts in the assembly process of mechanical equipment and electronic equipment. There may be dozens or even hundreds of screws to be locked on a piece of mechanical equipment. In order to improve work efficiency and reduce the labor burden of workers, , people invented the automatic screw locking machine.

The advent of the "air-blown" automatic screw machine greatly improves work efficiency because it can automatically replenish materials. The hand-held automatic screw machine is flexible and easy to operate. For example, the Chinese patent with publication number CN204524739U discloses a first-level buffer The air-blowing automatic screw locking machine of the device is composed of a machine table, an X-axis module, a Y-axis module, a Z-axis module, a screw head, an X-axis module bracket and an air-blowing feeding device. The Y There are two sets of axis modules, which are installed horizontally on the upper plane of the machine platform to drive the front and rear displacement of the workbench, forming a dual-station operating platform; the X-axis module is installed horizontally on the X-axis module behind the machine platform. The set of brackets is used to drive the left and right displacement of the screw head; the Z-axis module is installed vertically on the X-axis module and is used to drive the up and down displacement of the screw head; the air blowing feeding device is respectively Installed on the Z-axis module and machine table.

But there are obvious limitations:

(1) The screw locking module needs to be fixed on the XYZ module or the four-axis robotic arm. It can automatically lock the screws according to the set program. However, after each screw is locked, it must be returned to the screw feeder to retrieve materials. A large number of Time is consumed in the retrieval action, seriously affecting efficiency;

(2) Because the magnetic suction type uses the magnetism of the bit to hold the screws, it can only be applied to iron screws;

(3) The screw transportation pipeline uses the most common round high-pressure air plastic hose. Compressed air is used to blow the screws through the transportation pipeline to the screw chuck. During the transportation process, the screws pass through the transportation pipe and the chuck, and must be kept " "Head and foot" means that the cap head of the screw is on the top and the end of the screw is on the bottom. For this reason, it can only be used on slender screws (the length of the screw is at least 1.2 times the diameter of the cap head), otherwise it will flip over during transportation;

(4) The inner diameter of the conveying pipe and the inner diameter of the screw hole above the chuck must match the screw. Oversized screws will flip over and small screws cannot pass. In fact, each screw machine is tailor-made for a specific screw and is universal. The performance is very poor, and there are many types of screws, especially the diameters of the screw cap heads. This greatly limits the scope of use of the screw machine. Especially now that product updates are getting faster and faster, the screws used after product updates will also After the change, the original screw machine will no longer be used.

When the high-pressure air duct 23 is connected to the vacuum generator 29, the suction and blowing nozzle 223 moves toward the load. Inhaling air in the tool conveying pipe 25 can cause the screw carrier 26 in the carrier conveying pipe 25 to move to the screw feeding hole 228 and hover, making it easier for the screws to enter the screw carrier 26 . When the high-pressure air duct 23 is connected to the high-pressure air source 28, the suction and blowing nozzle 223 blows air into the carrier conveying pipe 25, which can cause the screw carrier 26 in the carrier conveying pipe 25 to quickly move downward to the screw discharging mechanism.

The screws in the tool 26 are discharged from the T-shaped discharging slot 244 on the front side of the discharging module base 241. Since they all adopt a T-shaped slot structural design, they can be adapted to various types of screws, as long as the screw head of the screw is not It only needs to exceed the maximum or minimum limit diameter requirement of the T-slot.

By setting the transverse cross-section of the carrier body 261 to a non-circular shape, the carrier body 261 will not easily rotate in the non-circular carrier conveying tube 25. If it is designed to be circular, the screw carrier 26 will During the transportation process, it is easy to deflect in the lateral direction. As a result, at the screw feeding and screw discharging points, a complex mechanism for secondary positioning of the loader needs to be added. The structure is complex and bloated and cannot be operated by hand. By providing a T-shaped slot 262 on the front side of the carrier body 261, it is convenient to load various types of screws, as long as the screw heads and screw columns do not exceed the maximum or minimum limit requirements of the T-shaped slot 262.

After the screw is blown into the T-shaped slot 262 of the screw carrier 26 from the outside, the sealing shutter driving cylinder 222 drives the sealing shutter again. 224 moves up, close the screw feeding hole 228 on the feeding tube 227, then the solenoid valve 27 switches the air path, the suction and blowing nozzle 223 is connected to the high-pressure air source 8 and blows air into the carrier conveying pipe 25, and the air flow will The screw carrier 26 carrying the screws is blown into the carrier cavity 246 of the screw discharging mechanism 24, and then the screws in the screw carrier 26 are removed from the front of the discharging module seat 241 through the blowing air nozzle 242 in the screw discharging mechanism 24. The T-shaped discharge chute 244 on the side is transported to the chuck mechanism 3, and then the solenoid valve 27 switches the air path to connect with the vacuum generator 29 again, and the suction and blowing air nozzle 223 sucks air into the carrier delivery pipe 25, and the screw carrier Under the action of the difference in internal and external air pressure, the tool 26 is sucked by the suction and blowing nozzle 223 and hovers in the feeding tube 227, and then the feeding of the next screw is repeated. The screw carrier 26 is used to replace the traditional direct screw loading. The accuracy and efficiency of the up and down reciprocating cycle of the screw carrier 26 are very high, and the screw carrier 26 can be adapted to transport a variety of different types of screws, and has strong adaptability. It solves the problem in the existing technology that each screw machine can only be customized for a specific screw and has poor versatility.

A semi-circular arc-shaped groove 3113 is provided on the alignment seat 3112. The purpose of setting the semi-circular arc-shaped groove 3113 is It is convenient for the electric screwdriver to pass through the semi-circular arc-shaped groove 3113. A Γ-shaped groove 3114 is provided on the front side of the half-chuck body 3111 below the alignment seat 3112. The Γ-shaped groove 3114 is formed from the half-chuck body 3111. The front side extends inward to the inside of the rear side of the half-chuck body 3111 but does not penetrate the rear side of the half-chuck body 3111. During actual operation, when the screw enters the Γ-shaped groove 3114 under the action of external force, the rear side faces the The screws are blocked to prevent the screws from leaking out from the rear side of the half-chuck body 3111. The transverse and longitudinal intersections at the top of the Γ-shaped groove 3114 are set to be tapered to facilitate the positioning of the screws after entering the Γ-shaped groove 3114;

Referring to Figures 17 and 18, the top of the half-collet body 3111 is also provided with a spring mounting hole 3115, and the return spring 313 is installed in the spring mounting hole 3115.

The front side of the closed T-shaped feed chute enters the T-shaped feed chute. Since the T-shaped feed chute does not penetrate the rear side of the half-chuck body 3111, the rear side will block the screws to prevent the screws from being clamped. The rear side of the head leaks out. After the screw enters the T-shaped feed trough, it will fall into the conical inner cavity with a large top and a small bottom set at the horizontal and vertical junction of the top of the T-shaped feed trough to achieve precise positioning of the screw. Due to the structural design of the T-shaped feed chute, it can be adapted to various types of screws, as long as the screw head of the screw does not exceed the maximum or minimum limit diameter requirements of the T-shaped feed chute. Compared with the traditional clamp The head can only match a single type of screw, and its adaptability is greatly enhanced. When the screw enters the T-shaped feed slot and is accurately positioned, the electric screwdriver can penetrate the left half chuck 311 and the right half chuck 312.
