Referring to fig. 2-10, in a first embodiment of a forward and reverse sorting assembly apparatus 1100 for detecting sleeve in an expansion bolt assembly system according to the present invention, referring to fig. 2, a main body thereof includes a compressing assembly 1101, a radiating assembly 1102 and a detecting 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.

Referring to fig. 3, in a second embodiment of the apparatus 1100 for inspecting a positive and negative sleeve sorting assembly of the present invention, the arrangement of its positions is optimized, the angle occupied by the monitor 1103a plus the gap is defined as θ, and in a top view, the hold-down assembly 1101 includes a first centerline m1 (solid line) and a second centerline m2 (solid line) that are perpendicular to each other. 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.

Referring to fig. 4, in this embodiment, the device for sorting and assembling the expansion bolt sleeve includes a fourth vibration unit 1000, a fourth conveying unit 1200, a device 1100 for detecting the forward and reverse directions of the sleeve, and a sleeve dropping unit 1300, in which the fourth vibration unit 1000 is a container capable of containing materials and vibrating, and is capable of regularly vibrating irregular materials in the container along a track from the container in a vibrating manner, for example, a vibration plate, under a hopper of which a pulse electromagnet is arranged, so that the hopper vibrates in a vertical direction, and the hopper is driven by an inclined spring sheet to perform torsional vibration around a vertical axis thereof. 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. 5 and 6, 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. The fourth vibration unit 1000 includes a fourth vibration member 1001, a fourth extension guide 1002, and a fourth guide pipe 1003, wherein 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. 6, 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.

Referring to fig. 7 and 8, a schematic view of a clamping unit according to a third embodiment of an apparatus for sorting and assembling expansion bolt sleeves according to the present invention is different from the second embodiment in that: the fourth conveying unit 1200 also includes a fourth pinch assembly 1201 and a second pinch assembly 1202. The specific embodiment is as follows: when the sleeve is bound at the constraint end 1003b, the sleeve needs to be conveyed to the device 1100 for detecting the forward and reverse directions of the sleeve through the fourth conveying unit 1200 for detecting the in-out state, in this embodiment, the fourth conveying unit 1200 comprises a fourth clamping assembly 1201 and a second clamping assembly 1202, wherein the fourth clamping assembly 1201 comprises a ninth screw 1201c, an extension rod 1201a and a pneumatic clamp 1201b, one end of the ninth screw 1201c is provided with a sixteenth driving piece 1201c-1, and the other end is provided with a balance block, and the fourth clamping assembly 1201 is balanced by the balance block to keep stable. The extension rod 1201a has one end connected to the ninth lead screw 1201c and the other end connected to the pneumatic clamp 1201 b. The extension rod 1201a is driven to move on the ninth screw 1201c along its placement orientation by the sixteenth driving member 1201c-1 such that the pneumatic clamp 1201b approaches and clamps the material, and the clamped material moves horizontally under the drive of the extension rod 1201 a. The pneumatic clamp 1201b drives the opening and closing of the arms of the clamp by the air cylinder, thereby clamping the sleeve.

Referring to fig. 8, the second clamping assembly 1202 includes a lateral transfer member 1202a and a longitudinal transfer member 1202b, wherein the lateral transfer member 1202a includes a thirty-first driving member 1202a-1, a seventh lead screw 1202a-2, and a fourth moving block 1202a-3, one end of the seventh lead screw 1202a-2 is connected to the thirty-first driving member 1202a-1, and the other end is connected to a balance weight by which the thirty-first driving member 1202a-1 is balanced to be stabilized. The fourth moving block 1202a-3 is sleeved on the seventh lead screw 1202a-2 and moves along the seventh lead screw 1202 a-2. The longitudinal conveying member 1202b comprises a thirty-second driving member 1202b-1, an eighth screw 1202b-2 and a second moving block 1202b-3, one end of the eighth screw 1202b-2 is fixedly connected with the fourth moving block 1202a-3, the other end is connected with the thirty-second driving member 1202b-1, one end of the second moving block 1202b-3 is sleeved on the eighth screw 1202b-2, and the second moving block 1202b-3 extends outwards in the direction perpendicular to the eighth screw 1202b-2 and moves along the eighth screw 1202b-2, and the other end is provided with a fixed block 1202b-2' for clamping materials.

The second pinching assembly 1202 differs from the fourth pinching assembly 1201 in that the second pinching assembly 1202 has a screw structure capable of moving up and down, not only in the front-rear direction, but also in the up-down direction, and the second pinching assembly 1202 effects the front-rear movement and up-down movement of the fixed block 1202b-3 'by the lateral conveying member 1202a and the longitudinal conveying member 1202b, and since the fixed block 1202b-3' entrains the material movement, the material is caused to move through the second pinching assembly 1202 and is transferred to the sleeve-dropping unit 1300.

Fig. 9 and 10 are schematic views showing a drop unit structure of a device for sorting and assembling expansion bolt sleeves according to a fourth embodiment of the present invention, which is different from the fourth embodiment in that: the sleeve drop unit 1300 also includes a first drop assembly 1301 and a second drop assembly 1302.
