The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Referring to fig. 1, a first embodiment of a device 1100 for inspecting the front and back of a sleeve according to the present invention includes a compression assembly 1101, a radiation assembly 1102, and an inspection assembly 1103. The hold down assembly 1101 holds down the sleeve to be inspected and monitors the presence or absence of light source leakage from the radiation assembly 1102 by the inspection assembly 1103. The compression assembly 1101 includes a tightening portion 1101a and a first placement portion 1101b, wherein forward movement of the tightening portion 1101a clamps the sleeve and reverse movement of the tightening portion unclamps the sleeve, and the first placement portion 1101b is disposed at a central axis of the compression assembly 1101 and is hollow for placement of the sleeve. The detecting unit 1103 is placed below the pressing unit 1101, and the end of the sleeve falling in the first placing portion 1101b is detected by the monitoring units 1103a spaced apart to determine the forward and reverse directions of the sleeve. The radiation assembly 1102 is placed under the first placement portion 1101b and is simultaneously disposed under the monitoring piece 1103a, which facilitates better detection.
Wherein the tightening part 1101a includes a third tightening port 1101a-1 and a jaw 1101a-2, and the movement direction of the jaw 1101a-2 is controlled by the third tightening port 1101 a-1. If the third screw port 1101a-1 is rotated in the forward direction, the claw 1101a-2 is moved in the direction of the central axis of the pressing unit 1101, and if the third screw port 1101a-1 is rotated in the reverse direction, the claw 1101a-2 is moved in the opposite direction of the central axis of the pressing unit 1101. The monitoring pieces 1103a are arranged at equal intervals on the outer ring of the lower end of the first placement portion 1101b, and the number of overlapping of the gaps existing between the monitoring pieces 1103a and the gaps of the sleeve is not more than 1". It should be noted that, the "the number of overlapping gaps between the two monitoring pieces 1103a and the gaps of the sleeve is not greater than 1" means that when the monitoring pieces 1103a are disposed, there is a gap between the two monitoring pieces, and if the detected sleeve faces down (i.e., the end of the sleeve having the gap), there is a gap between the sleeves, in this embodiment, the number of overlapping gaps between the two gaps is at most one, that is, when one gap of the sleeve is aligned with a certain gap between the monitoring pieces 1103a, the other gaps of the sleeve cannot overlap with the gap between any one of the monitoring pieces 1103 a.
In both embodiments of the device 1100 for detecting sleeve positive and negative according to the present invention, the arrangement of the positions is optimized, and referring to fig. 2, the angle occupied by the monitoring element 1103a plus the angle of the gap is defined as θ, and the hold-down assembly 1101 includes a first center line m1 (solid line) and a second center line m2 (solid line) perpendicular to each other in a top view. When the monitoring elements 1103a are distributed, the center line (dotted line) of the first monitoring element 1103a-1 coincides with the first center line m1 (solid line) of the pressing assembly 1101, that is, the included angle between the center line (dotted line) of the first monitoring element 1103a-1 and the first center line m1 (solid line) of the pressing assembly 1101 is 0 °, and the included angle between the center line (dotted line) of the second monitoring element 1103a-2 and the first center line m1 (solid line) of the pressing assembly 1101 is θ/2. The included angle of the center line (broken line) of the third monitor 1103a-3 and the second center line m2 (solid line) of the hold-down assembly 1101 is θ/4, and the included angle of the center line (broken line) of the third monitor 1103a-4 and the second center line m2 (solid line) of the hold-down assembly 1101 is 3/4 times θ. By this arrangement, it is realized that "the number of overlapping of the gaps existing between the monitoring pieces 1103a and the gaps of the sleeve is not more than 1". The monitoring unit 1103a may be a sensor, may be an inductor, and may receive an induction light source.
The invention also provides a device for sorting and assembling expansion bolt sleeves, referring to fig. 3, which is a schematic overall structure of a first embodiment of the invention, in this embodiment, the device for sorting and assembling expansion bolt sleeves comprises a fourth vibration unit 1000, a fourth conveying unit 1200, a device 1100 for detecting the forward and reverse directions of the sleeves, and a sleeve dropping unit 1300, specifically, the fourth vibration unit 1000 is a container capable of containing materials and is capable of vibrating, so that irregular materials in the container can be regularly vibrated along a track from the container in a vibrating manner, for example, a vibration disc, a pulse electromagnet is arranged below a hopper of the vibration disc, so that the hopper can vibrate in a vertical direction, and an inclined spring piece drives the hopper to perform torsional pendulum vibration around a vertical axis of the hopper. The parts in the hopper rise along the spiral track due to the vibrations. In the ascending process, through a series of track screening or posture change, parts can automatically enter an assembling or processing position in a unified state according to the assembling or processing requirements, and the work purpose is to automatically, orderly, directionally and accurately arrange unordered workpieces through vibration and convey the unordered workpieces to the next working procedure. In the invention, the material is a sleeve of an expansion bolt, the principle of the expansion bolt is that after the expansion bolt is punched into a hole on the ground or a wall surface, a nut on the expansion bolt is screwed by a wrench, the bolt moves outwards, an outer metal sleeve is still, and then the large head under the bolt expands the metal sleeve to expand the whole hole, and at the moment, the expansion bolt cannot be pulled out. The metal sleeve of the expansion bolt is widely applied to the connection of building components, the installation of equipment and the like, and the materials are the metal sleeve of the expansion bolt.
The fourth conveying unit 1200 clips the material vibrated by the fourth vibrating unit 1000 and conveys the material to the device 1100 for detecting the front and back of the sleeve, and because the two ends of the sleeve are different, one end has a gap and the other end has no gap, the device 1100 for detecting the front and back of the sleeve needs to detect whether the dropped sleeve is in a state meeting the specification (whether the detected end has a gap), if not, the sleeve can fall into the sleeve dropping unit 1300 to adjust the state, the adjusted sleeve and the sleeve meeting the specification are summarized together, and then the whole assembly of the expansion bolt is completed.
Referring to fig. 4 and 5, a schematic diagram of a vibration unit of the vibration unit in a second embodiment of the device for sorting and assembling expansion bolt sleeves according to the present invention is shown, which is different from the first embodiment in that: the fourth vibration unit 1000 includes a fourth vibration member 1001, a fourth extension guide 1002, and a fourth guide tube 1003. The implementation scheme is as follows: the fourth vibration unit 1000 is a container capable of containing materials, and is capable of vibrating, so that irregular materials in the container are regularly vibrated out along a track from the container in a vibrating manner, and the materials which are vibrated out need to be conveyed to the fourth conveying unit 1200 in a directional manner. Wherein, referring to fig. 4 and 5, the fourth vibration unit 1000 includes a fourth vibration member 1001, a fourth extension guide 1002 and a fourth guide pipe 1003, an outlet end of the fourth vibration member 1001 is connected to the fourth extension guide 1002, and the fourth extension guide 1002 is connected to the fourth guide pipe 1003, and referring to fig. 5, in order to allow a sleeve vibrated by the fourth vibration unit 1000 to enter the fourth guide pipe 1003, a guide head 1003a is provided at one end of the fourth guide pipe 1003, which is connected to the fourth extension guide 1002 to be connected to the fourth guide pipe 1003, and guides the sleeve to drop into the fourth guide pipe 1003. When the sleeve vibrates out of the fourth vibration member 1001, it falls onto the attached fourth extension guide 1002, after which the guiding action of the fourth guide pipe 1003 slides down the fourth guide pipe 1003, and falls to the bottom end. At this time, if there is no binding force at the bottom end of the fourth guide tube 1003, the material may fall, so that it is difficult to clamp the material when the fourth conveying unit 1200 clamps, if there is too large binding force at the bottom end of the fourth guide tube 1003, it is difficult to push the material when the fourth conveying unit 1200 clamps after the material falls to the bottom end, the material with too small thrust is not moved, and the fourth guide tube 1003 is damaged by the material with too large thrust. Therefore, as a preferable scheme, the other end is provided with a constraint end 1003b, which is equivalent to a bayonet with elasticity, the bottom end of the fourth guide tube 1003 may be cut into a plurality of strip-shaped vertical bars, or a component similar to a wire clamping device (the diameter of the bayonet of the wire clamping device is smaller than that of the guide tube), and the constraint sleeve does not fall off. Because the constraint end 1003b has elastic force, when the material falls to the end of the fourth guide pipe 1003, the material will not fall directly, but will be blocked by the constraint end 1003b in the upper half, after being held by the fourth conveying unit 1200, the constraint end 1003b is elastically deformed in the moving process, and after leaving the constraint end 1003b, the elastically deformed constraint end 1003b returns to its original shape by its own elastic property.
The fourth conveying unit 1200 clips the material vibrated by the fourth vibrating unit 1000 and conveys the material to the device 1100 for detecting the front and back of the sleeve, and because the two ends of the sleeve are different, one end has a gap and the other end has no gap, the device 1100 for detecting the front and back of the sleeve needs to detect whether the dropped sleeve is in a state meeting the specification (whether the detected end has a gap), if not, the sleeve can fall into the sleeve dropping unit 1300 to adjust the state, the adjusted sleeve and the sleeve meeting the specification are summarized together, and then the whole assembly of the expansion bolt is completed.
