In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present invention is not limited to the specific embodiments disclosed below.

Further, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic can be included in at least one implementation of the invention. 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. 16, the present invention provides an automatic expansion bolt assembling apparatus for assembling an expansion bolt as shown in fig. 1, which includes a work platform a, a bolt sorting and assembling device 100, a sleeve sorting and assembling device, a flat gasket sorting and assembling device 400, a spring pad sorting and assembling device 600, a nut tightening device 1500, and a finished product discharging device. Firstly, a bolt is placed on a working platform A through a bolt sorting device 100, after the bolt is screwed, the working platform A is rotated to a sleeve sorting device, a sleeve is placed on the bolt, then the working platform A is rotated again to a flat gasket sorting and assembling device 400, the sorted flat gasket is placed on an expansion bolt to be assembled, then the flat gasket is rotated to a spring gasket sorting device 600, after the spring gasket is placed on the expansion bolt to be assembled, the expansion bolt is rotated to a nut screwing device 1500, after the nut is screwed, the assembled expansion bolt is placed in a finished product blanking device.

As shown in fig. 2, which is a schematic view of the overall structure of the first embodiment of the first conveying assembly 100 in the bolt sorting device in the assembly system of expansion bolts, in this embodiment, the main body includes a third fixing member 101 and a first flipping member 102, and the first flipping member 102 is disposed above the third fixing member 101. Referring to fig. 3, the third fixing member 101 includes a first pushing member 101a, a first bottom plate 101c, and a first supporting frame 101b, and a material is turned over from the first turning member 102 and falls onto the first bottom plate 101c, and is pushed forward by the first pushing member 101 a. The first pushing member 101a moves with the conveyed material, the first supporting frame 101b is vertically arranged at two ends of the first bottom plate 101c, and the first bottom plate 101c is provided with a first groove 101c-1. The first supporting frame 101b is in an L shape, and has a vertical height greater than a length of a bolt to be assembled, so as to support the first overturning member 102.

In this embodiment, referring to fig. 2 and 3, the first pushing member 101a is fitted in the first groove 101c-1, including the first lead screw 101a-1 and the first sandwiching member 101a-2, the first lead screw 101a-1 is placed in the first groove 101c-1, one end of which is connected to the face of the first groove 101c-1, and the other end of which is provided with the first driving member 101a-1'. One end of the first clamping and conveying piece 101a-2 is sleeved on the first screw rod 101a-1, and the other end of the first clamping and conveying piece is parallel to the first bottom plate 101c and clamps and pushes materials. The first driving member 101a-1' drives the first gripping member 101a-2 along the first lead screw 101a-1, and preferably, the first gripping member 101a-2 employs a pneumatic clip.

Referring to fig. 4, the first flipping unit 102 includes a first guide tube 102a, a second guide tube 102b, a first carriage 102c, and a first rotating body 102d. The first overturning piece 102 is connected with the first supporting frame 101b through the first carrying frame 102c, so that the first overturning piece 102 is stable, the first guide tube 102a is arranged at the upper end of the first rotating body 102d, the second guide tube 102b is arranged at the lower end of the first rotating body 102d, the center lines of the first guide tube 102a and the second guide tube 102b are on the same straight line, the first rotating body 102d comprises a first rotating shell 102d-1 and a first rotating motor 102d-2, a first cross-shaped drop groove s is formed in the first rotating shell 102d-1 in a wrapping mode, the drop opening of the first drop groove s is aligned with the first guide tube 102a, and the rotated drop opening of the first guide tube 102b is aligned with the opening of the second guide tube 102b, namely, a bolt drops along the second guide tube 102 b. The rotation shaft of the first rotary housing 102d-1 is connected to the first rotary motor 102d-2 to rotate the first drop slot s, thereby adjusting the state of the bolts therein. For example: the transported bolt is big end up, the threaded end is down, the bolt is put into the first turning piece 102 after being transported, and falls into the first drop slot s, and the position of the bolt is adjusted. The bolts fall into the first dropping grooves s in one fourth of the cross shape, the bolts become big-end downwards after rotating 180 degrees through the first dropping grooves s in the cross shape, and the threaded ends face upwards. The meaning of setting the first drop slot s to be in a cross shape is that limited space resources are reasonably utilized, so that position rotation of a plurality of sleeves can be completed in one process.

When the bolt falls from the lower port of the second guide tube 102b, if the distance from the lower port of the second guide tube 102b to the first bottom plate 101c is greater than the length of the bolt, the first clamping member 101a-2 cannot clamp the bolt. To ensure that the first clamping member 101a-2 can clamp and push out the bolt under the second guide tube 102b, the distance from the lower port of the second guide tube 102b to the first bottom plate 101c is less than the length of the material (i.e., the bolt). If the binding force at the bottom end of the second guide tube 102b is too large, the first clamping member 101a-2 clamps the material and is difficult to push after the bolt falls to the first bottom plate 101c, if the pushing force is too small, the bolt is not moving, and if the pushing force is too large, the bolt will damage the first guide tube 102 a. Preferably, a restraining member 102b-1 is provided at one end of the second guide tube 102b near the first bottom plate 101c, which corresponds to a bayonet with elasticity, and the bottom end of the second guide tube 102b may be cut into a plurality of strips, or may be similar to a wire clamping device (the diameter of the bayonet of the wire clamping device is smaller than that of the guide tube), so that the bolt is restrained and prevented from falling. Because the constraint piece 102b-1 has elastic force, when the bolt falls to the end of the second guide tube 102b, the upper half edge of the bolt is clamped by the constraint piece 102b-1, after the bolt is clamped by the first clamping piece 101a-2, the constraint piece 102b-1 is elastically deformed in the moving process, and after the bolt leaves the constraint piece 102b-1, the elastically deformed constraint piece 102b-1 restores its original shape through the elastic property of the bolt.

The present invention also provides an automatic expansion bolt assembling apparatus, the main body of which includes a first conveying assembly 100, a first sorting assembly 200 and a first locking assembly 300, and referring to fig. 5, the first sorting assembly 200 includes a first vibrating member 201, a first extension guide 202 and a first picking member 203. The first vibrating member 201 (vibrating plate) is capable of generating a rotational vibrating force so that the bolts sequentially move on the bolt material path 201 a-1. The principle is as follows: the bottom cavity of the first vibrating member 201 (vibrating plate) is a containing chamber containing a certain enclosed space, and a main electromagnet and a main vibrating spring are arranged in the containing chamber, in one embodiment, the main vibrating spring can be a plate spring, and the main vibrating spring is obliquely connected with the bottom end and the top end of the containing chamber, so that the first vibrating member 201 (vibrating plate) generates rotary vibrating force, and thus torsional vibration and vertical linear vibration on a vertical shaft are generated simultaneously. In this embodiment, when the power is turned on, the main electromagnet generates a suction force, and under the effect of the electromagnetic suction force, the first vibration member 201 (vibration plate) deviates from the static equilibrium position and moves, and then makes a synchronous torsion around the central axis, while the main vibration spring generates an elastic deformation, and when the electromagnetic suction force becomes small, the first vibration member 201 (vibration plate) starts to change the moving direction sharply and reaches a certain upper limit beyond the initial static equilibrium position, because the main vibration spring has enough elastic deformation energy, and thus repeatedly goes up and down, a high-frequency micro-amplitude vibration is formed. As a result of the high-frequency micro-amplitude vibration generated by the first vibrating member 201 (vibrating plate), each point of the bolt material path 201a closely connected to the first vibrating member 201 (vibrating plate) itself except the central axis is subjected to the high-frequency micro-amplitude vibration along the respective small-section spatial spiral line track. In the process that the bolts are conveyed along the bolt material channel 201a, the unification mechanism on the bolt material channel 201a enables part parts to form a unified posture, the bolts float in the air due to the fast descending speed, the bottoms of the falling bolt material channels 201a are conveyed upwards in a spiral mode along the bolt material channel 201a again under the action of gravity, automatic directional arrangement is carried out, and finally the bolts are discharged from the tail ends of the bolt material channels 201a one by one and conveyed to the first extension guide rod 202. One end of the first extension guide 202 is connected to the end of the bolt material passage 201a in the first vibration member 201, and the bolt is carried from the bolt material passage 201a to the first extension guide 202. The end of the first extension bar 202 (i.e., the bolt outlet) is "concave" and the diameter of the recessed area is less than the maximum diameter of the bolt. A first picking member 203 is arranged below the first extending guide rod 202, the first picking member 203 comprises a fourth driving member 203a and a pushing member 203b, and the fourth driving member 203a drives the pushing member 203b to move so as to push the bolt on the first extending guide rod 202. The pushing member 203b includes a contact arm end 203b-1 and a turntable end 203b-2, and the pushing member 203b is in the shape of a star, namely: the tip is "contact arm end 203b-1". The contact arm end 203b-1 can abut against the bolt, the fourth driving member 203a is connected to the turntable end 203b-2, and when the fourth driving member 203a drives the turntable end 203b-2 to rotate, the bolt is pushed by the contact arm end 203b-1 to advance, and then the bolt enters a specific position where the previous bolt is located, at this time, the fourth driving member 203a drives the contact arm end 203b-1 to push the bolt at the specific position to move.

Referring to fig. 6, the first locking assembly 300 includes a first tightening member 301 and a second fixing member 302. The first tightening member 301 includes a second driving member 301a, a third driving member 301b, and a third pushing member 301c, the third pushing member 301c is connected to the second driving member 301a, the second driving member 301a is connected to the third driving member 301b, the second driving member 301a drives the third pushing member 301c to translate forward, and the third driving member 301b drives the second driving member 301a (because the third pushing member 301c is connected to the second driving member 301a, that is, the third driving member 301b drives the third pushing member 301 c) to rotate. The second fixing member 302 includes a second supporting frame 302a and a second flat pushing groove 302b, the second flat pushing groove 302b is disposed above the second supporting frame 302a, and the second flat pushing groove 302b is supported by the second supporting frame 302 a.

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 plurality of monitoring pieces 1103a are disposed, gaps are formed between two adjacent monitoring pieces 1103a, and if the detected sleeve faces downward (i.e., the end of the sleeve having the gap), then there is a gap between the sleeves, in this embodiment, the number of overlapping gaps between the two gaps is only one at most, that is, when one gap of the sleeve is aligned with one 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. 8, in a second embodiment of the apparatus 1100 for inspecting a front-to-back sorting assembly of sleeves according to the present invention, the arrangement of the positions thereof is optimized, the angle occupied by the monitor 1103a plus the angle of the gap is defined as θ, and in a top view, for clearly explaining the positional angular relationship, the pressing member 1101 is set to have a first center line m1 (solid line) and a second center line m2 (solid line), and both (m 1 and m 2) are perpendicular to each other. When the plurality of 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. 9, in the present embodiment, the automatic expansion bolt assembling apparatus 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, and in particular, the fourth vibration unit 1000 is a container capable of containing materials and vibrating, and regularly vibrates irregular materials in the container along a track from the container in a vibration manner, for example, a vibration plate, under a hopper of which a pulse electromagnet is provided, so that the hopper can vibrate in a vertical direction, and an inclined spring piece drives the hopper 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. 11 and 10, a schematic diagram of a vibration unit structure of the vibration unit in a second embodiment of the automatic expansion bolt assembling apparatus of 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. 11, 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.

Referring to fig. 12 and 13, which are schematic views of a structure of a clamping unit according to a third embodiment of the automatic expansion bolt assembling apparatus of the present invention, the difference in this embodiment from the second embodiment is 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.

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-3' 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. 14 and 15 are schematic views showing a drop unit structure of an automatic expansion bolt assembling apparatus 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. Specifically, after the device 1100 for detecting the front and back of the sleeve is detected, the second clamping assembly 1202 clamps the sleeve after the detection, and the sleeve is separated and collected in the sleeve falling unit 1300, and the first falling assembly 1301 and the second falling assembly 1302 are arranged in parallel.

For example: when the sleeve head faces downwards and the required sleeve is assembled, if the sleeve clamped by the second clamping assembly 1202 is arranged to face upwards, the second clamping assembly 1202 clamps the sleeve to the first dropping assembly 1301 for direct collection, if the sleeve is detected to face downwards, the sleeve is out of specification, adjustment is required, the second clamping assembly 1202 clamps the sleeve to the second dropping assembly 1302, the sleeve falls into a second dropping groove s1 of one fourth of the cross shape, the sleeve with the head facing downwards is changed to face upwards through 180 degrees of rotation of the second dropping groove s1 of the cross shape, at the moment, the sleeve is exactly corresponding to a dropping pipe mouth of the lower end, rotation dropping of the sleeve is realized, collection conveying is carried out after adjustment, and assembly of the expansion bolt is completed. The meaning of setting the second drop slot s1 in the cross shape is that limited space resources are reasonably utilized, and the position rotation of a plurality of sleeves can be completed in one process.

Preferably, the collecting unit 1400 further comprises a third accommodating space 1401 and a third conveying pipe 1402, wherein the third accommodating space 1401 encapsulates the discharge ports of the first falling component 1301 and the second falling component 1302, so that materials (sleeves) can fall into the third accommodating space 1401, and the materials (sleeves) are conveyed out along the third conveying pipe 1402.
