Problems solved by technology

Due to the increasing cost of labor, many factories use screw machines instead of manual operations, but the current screw machines on the market cannot meet the demand
Disadvantage 1: The automation level of the existing screw locking machine is not high enough, and the error rate is also very high. The probability of the screw being crooked is as high as 3%.
Disadvantage 2. The existing screw machine can only lock large screws with a diameter of more than 1mm at present, and cannot lock small screws with a diameter of less than 1mm. However, for the watch, toy and mobile phone manufacturing industries, the screws that need to be locked are all with a diameter of less than 1mm. screw, which has caused the existing screw machine to be unable to meet the needs of the industry
The third disadvantage is that the efficiency of the existing screw machine is not high, and it takes 4 seconds to lock a screw

Embodiment 1

[0031] Embodiment one, with reference to Figure 1 to Figure 5 , the screw positioning mechanism of the present invention includes a screw positioning seat 1, and the screw positioning seat 1 is vertically provided with a screw channel 2 for the screwdriver head and the screw to pass through, and at least 2 screw channels are evenly distributed on the same horizontal surface on the inner peripheral wall of the bottom of the screw channel 2. Undertake the elastic wire 3 of the screw that falls into the screw channel. The screw 6 in this embodiment includes a screw head 61 and a screw rod 62 , and the bottom surface of the screw head 61 is a slope 610 . The diameter of the screw channel is equal to the diameter of the screw head plus tolerance, allowing the screw to be dropped or blown from above the screw channel. Screws can be fed manually or fed or blown by a screw feeder.

[0032] Preferably, the number of elastic threads 3 is 3-8. The elastic thread 3 can also be replace...

Embodiment 2

[0045] Embodiment 2, the main structure, principle and function of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The difference is that, as Figure 6~7 As shown, the mounting groove 4 has an upper wall 41 and a lower wall 42, the vertical section of the upper wall 41 is a horizontal straight line, and the lower wall 42 is a downwardly curved arc surface, and the centrifugal end of the elastic sheet 3 is fixed in the mounting groove 4 , its centripetal end 31 extends out of the notch and faces the center of the screw channel, the upper side of the elastic sheet 3 contacts the straight upper wall 41 of the installation groove 4, the centripetal end 31 of the elastic sheet is perpendicular to the screw channel 2, and a plurality of The centripetal end 31 of the elastic piece encloses a limiting opening 5 for the screw rod to pass through. The design of the flat upper wall 41 of the installation groove 4 in this embodiment is suitable for sc...

Embodiment 3

[0047] Embodiment 3, the main structure, principle and function of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The difference is that, as Figure 7-8 As shown, the mounting groove 4 has an upper wall 41 and a lower wall 42, the centripetal section of the lower wall 42 is a curved surface bent downward, the centripetal section of the upper wall 41 is a curved surface, and the centripetal section of the upper wall 41 is a curved surface. The section is higher than the centrifugal section, the tangent line of the intersection point of the upper wall and the screw passage is in a horizontal state, the centrifugal end of the elastic sheet 3 is fixed in the installation groove 4, and its centripetal end 31 protrudes from the notch and faces the center of the screw passage, the elastic sheet 3 The upper side of the upper side is in contact with the upper wall 41 of the mounting groove 4, and under the constraints of the upper wall 41, the cent...

Abstract

The invention discloses a screw positioning mechanism which comprises a screw positioning seat. A screw channel allowing a screwdriver bit and a screw to pass through is vertically formed in the screwpositioning seat. At least two elastic pieces / wires for bearing the screw falling into the screw channel are evenly distributed on the same horizontal plane of the inner peripheral wall of the bottomof the screw channel. Mounting grooves for mounting the elastic pieces / wires and restraining deformation of the elastic pieces / wires are formed in the inner peripheral wall of the screw channel. Theheights of the mounting grooves in the vertical direction are gradually increased in the direction from the interiors of the grooves to groove openings. The centrifugal ends of the elastic pieces / wires are fixed into the mounting grooves, and the centripetal ends of the elastic pieces / wires stretch out of the groove openings and face the center of the screw channel, and define a limiting opening allowing the screw and a threaded rod to pass through from top to bottom in the screw channel. Compared with the prior art, the screw positioning mechanism has the advantages that the screw can be automatically positioned, it is ensured that the screw is vertical and does not tilt, the accuracy rate is high, the machining speed is high, and the screw positioning mechanism is particularly suitable for a manipulator or a robot.

Description

technical field [0001] The invention relates to the technical field of screw machines, in particular to a screw positioning mechanism used in the assembly process of manipulators or robots. Background technique [0002] At present, in the manufacturing fields of watches, toys, and mobile phones, most factories still use manual labor to locate, insert, and tighten screws. Due to the increasing cost of labor, many factories use screw machines instead of manual operations, but the current screw machines on the market cannot meet the demand. Disadvantage 1: The existing screw locking machine is not highly automated, and the error rate is also very high. The probability of the screw being crooked is as high as 3%. Disadvantage 2. The existing screw machine can only lock large screws with a diameter of more than 1mm at present, and cannot lock small screws with a diameter of less than 1mm. However, for the watch, toy and mobile phone manufacturing industries, the screws that need...
