The first dividing disc is arranged above the machine table. Eight carriers 21 are arranged in a ring array above the rotating area of the first dividing disc. Figure 1 Only one is shown;

[0033] The main still includes empty carrier detection mechanism 30 provided above the machine table in sequence along the rotation direction of the first indexing disc for detecting empty carrier, screw feeding mechanism 40 provided above the machine table for screw feeding, first screw detection mechanism 50 provided above the non-rotation area of the first indexing disc for detecting whether the screw is short of material, product feeding mechanism 60 provided above the machine table for product feeding, shape detection mechanism 70 provided above the machine table for detecting whether the product is deformed, riveting mechanism 80 provided on the machine table for assembling the screw and the product, second screw detection mechanism 90 provided above the non-rotation area of the first indexing disc for detecting whether the screw is short of material, and product discharging mechanism 100 provided on the machine table for product sorting and discharging. The specific structure of each mechanism will be described below.

[0034] Based on the above structure, the general working process of the present application is as follows: the first indexing disc drives the eight carriers to rotate, when the carrier passes through the empty carrier detection mechanism position, the empty carrier detection mechanism will automatically detect whether the product above it has been discharged, when the carrier passes through the screw feeding mechanism position, the rivet feeding mechanism will put two screws in the carrier, when the carrier passes through the first screw detection mechanism position, the first screw detection mechanism will detect whether there are two screws on the carrier, when the carrier passes through the product feeding position, the product feeding mechanism will put a product on the carrier, when the carrier passes through the shape detection mechanism position, the shape detection mechanism will detect whether the product in the carrier is deformed or warped, when the carrier passes through the riveting mechanism position, the riveting mechanism will automatically rivet the product and the two rivets on the carrier together, when the carrier passes through the second screw detection mechanism position, the second screw detection mechanism will detect whether the screw is not pressed well, when the carrier passes through the product discharging mechanism, the product discharging mechanism will sort and discharge the riveting finished product according to the detection results of the shape detection mechanism, the first screw detection mechanism and the second screw detection mechanism.

[0035] Referring to Figure 2 As shown in the drawings, the empty carrier detection mechanism of the present application includes first inverted L-shaped frame 31 provided above the machine table and having its upper part directly opposite the first indexing disc, and first visual detection camera 32 provided on the bottom side of the upper part of the first inverted L-shaped frame. When the carrier is located below the empty carrier detection mechanism, the first visual detection mechanism will take a photo of the carrier for detection. The specific detection means is designed according to the computer system (this part is not the protection object of the present application, and will not be described in detail here).

[0036] Referring to Figure 3As shown, the screw feeding mechanism of the present application includes two spiral vibration discs 41 arranged side by side on the machine table, two discharge tracks 42 connected to the discharge ports of the two spiral vibration discs respectively, a first truss 43 arranged on the machine table beside the two spiral vibration discs and extending towards the first indexing disc, a first servo lead screw module 44 arranged on the side of the first truss beam towards the two spiral vibration discs, a first sliding plate 45 connected to the first servo lead screw module, a first lifting plate 46 slidingly connected to the first sliding plate through a first guide rail (not shown in the present application), a first cylinder 47 arranged above the first lifting plate and having its piston rod connected to the first lifting plate, a first transverse plate 48 arranged vertically on the first lifting plate, a second cylinder 49 arranged above the first transverse plate, a second lifting plate 401 connected to the piston rod of the second cylinder below the first transverse plate, and two electromagnetic suction heads 402 arranged below the second lifting plate and corresponding to the positions of the two discharge tracks. When the carrier reaches the position of the screw feeding mechanism, the first servo lead screw module drives the first sliding plate to the delivery end of the two discharge tracks, the first lifting plate is driven downward by the first cylinder, and the second lifting plate is driven downward by the second cylinder. When the two electromagnetic suction heads contact two screws in the two discharge tracks, they will be attracted (after the action is completed, the first cylinder drives the first lifting plate to reset, and the second cylinder drives the second lifting plate to reset). After that, the first servo lead screw module drives the first sliding plate above the carrier, the first cylinder drives the first lifting plate to descend again, and the second cylinder drives the second lifting plate to descend again. When the attracted rivets contact the carrier, the two electromagnetic suction heads will stop attracting the screws. At this time, the two screws complete the feeding work.

[0037] Reference Figure 4 As shown, the first screw detection mechanism of the present application includes a first stand 51 arranged on the non-rotating area of the first indexing disc, a third lifting plate 52 slidingly connected to the side of the first stand towards the carrier through a second guide rail (not shown in the present application), a third cylinder 53 arranged above the first stand and having its piston rod connected to the third lifting plate, a second transverse plate 54 arranged vertically on the third lifting plate, a third transverse plate 55 fixed below the second transverse plate through a first connecting column (not shown in the present application), and two contact switch sensors 56 arranged inside the second transverse plate and the third transverse plate and extending downward. When the carrier reaches the position of the first screw detection mechanism, the third cylinder drives the third lifting plate to descend. When the two contact switch sensors are lowered into position, if no screw is contacted, it means that the carrier lacks a screw. On the contrary, if the two contact switch sensors can be triggered and sensed, it means that the carrier does not lack a screw.

[0038] Reference Figure 5As shown, the product feeding mechanism of the present application comprises a second indexing disc 61 arranged on the machine table, a second truss 62 arranged on the machine table beside the second indexing disc and extending towards the second indexing disc, a second servo lead screw module 63 arranged on the side of the second truss beam towards the second indexing disc, a second sliding plate 64 connected to the second servo lead screw module, a fourth lifting plate 66 slidingly connected to the second sliding plate through a third guide rail 64, a fourth cylinder 67 arranged above the fourth lifting plate and having its piston rod connected to the fourth lifting plate, a fourth transverse plate 68 vertically arranged on the fourth lifting plate, a fifth transverse plate 69 fixed below the fourth transverse plate through a second connecting column, and two first pneumatic suction heads 601 arranged inside the fourth transverse plate and the fifth transverse plate and extending downward. In addition, four empty slots 611 are arranged on the rotating area of the second indexing disc, and three railings 604 for positioning the product are arranged on the rotating area of the second indexing disc around the four empty slots. A servo motor 602 is arranged on the machine table below the rotating area of the second indexing disc, and a lifting column 603 that can pass through the empty slots is connected to the servo motor. First, it is explained that a plurality of products positioned by the three railings are stacked above the plurality of holes and slots during the operation of the equipment. When the carrier reaches the product feeding mechanism, the second servo lead screw module drives the second sliding plate to the upper side of the second indexing disc. After reaching the position, the fourth cylinder drives the fourth lifting plate to descend until the four pneumatic suction heads contact the product and adsorb it after contacting the product. (When this action is completed, the fourth cylinder drives the fourth lifting plate to reset.) After that, the second servo lead screw module drives the second sliding plate to the upper side of the carrier, and then the fourth cylinder drives the fourth lifting plate to descend again. After descending to the position, the four pneumatic suction heads stop adsorbing the product, and the product can be placed on the carrier. In addition, it is also explained that the servo push rod will drive the lifting column to lift the stacked products in real time to ensure that the uppermost product maintains a certain height (after the products above each empty slot are grabbed, the servo push rod will drive the lifting column to reset, and at this time, the lifting column is located below the second indexing disc). If the products above each empty slot are grabbed, the second indexing disc will automatically rotate by a set angle. At this time, the products above the next empty slot will continue to be fed, and the electric push rod will continue to lift the products in the slot.

[0039] Reference Figure 6 As shown, the profile detection mechanism of the present application comprises a second inverted L-shaped frame 71 arranged above the machine table and having its upper part facing the first indexing disc, and a second vision detection camera 72 arranged on the upper bottom side of the second inverted L-shaped frame. When the carrier reaches the profile detection mechanism, the second vision detection camera will take a photo of the product on the carrier for detection. Similarly, the specific detection means is performed according to the system designed by the computer (this part is not the protection object of the present application, and will not be described in detail here).

[0040] ReferenceFigure 7 As shown, the riveting mechanism of the present application comprises a third inverted L-shaped frame 81 arranged on the machine table, a hydraulic cylinder 82 arranged above the upper portion of the third inverted L-shaped frame, a riveting die frame 83 connected with the piston rod of the hydraulic cylinder at the bottom of the third inverted L-shaped frame. When the carrier reaches the position of the riveting mechanism, the hydraulic cylinder drives the riveting die frame to descend, and then the riveting die frame rivets the product and the two screws together.

[0041] In one of the specific embodiments, the second screw detection mechanism of the present application has the same structure as the first screw detection mechanism. The working principle of the second screw detection mechanism of the present application is referred to the working principle of the first screw detection mechanism, which will not be described in detail herein.

[0042] Reference Figure 8 As shown, the product unloading mechanism of the present application comprises a qualified product unloading assembly line 1001 arranged side by side on the machine table, an unqualified product recycling box 1102, a third truss 101 arranged on the machine table beside the qualified product unloading assembly line and extending towards the direction of the second indexing disc, a third servo lead screw module 102 arranged on the side of the cross beam of the third truss facing the unqualified product recycling box, a third sliding plate 103 connected with the third servo lead screw module, a fifth lifting plate 104 slidingly connected with the third sliding plate through a fourth guide rail (not shown in the present application), a fifth cylinder 105 arranged above the fifth lifting plate and having its piston rod connected with the fourth lifting plate, a sixth transverse plate 106 vertically arranged on the fifth lifting plate, a pneumatic sliding table 107 arranged at the bottom of the sixth transverse plate, a seventh transverse plate 108 connected with the bottom of the pneumatic sliding table through a third connecting column (not labeled in the present application), and two second pneumatic suction heads 109 arranged at the bottom of the seventh transverse plate. When the carrier reaches the position of the unloading mechanism, the third servo lead screw module drives the third sliding plate to be directly above the carrier, the fifth cylinder drives the fifth lifting plate to descend, and after being positioned, the several second pneumatic suction heads suck the product on the carrier (at this time, the fifth cylinder drives the fifth lifting plate to reset). After that, the third servo lead screw module drives the third sliding plate to be directly above the unqualified product recycling box. If the product is unqualified, the fifth cylinder drives the fifth lifting plate to descend, and after being positioned, the two second pneumatic suction heads stop sucking the product, at which time the product is dropped into the unqualified product recycling box. If the product is qualified, the pneumatic sliding table drives the seventh transverse plate to extend above the qualified product unloading assembly line, the fifth cylinder drives the fifth lifting plate to descend, and after being positioned, the two second pneumatic suction heads stop sucking the product, at which time the product is dropped onto the qualified product unloading assembly line, and the qualified product unloading assembly line carries away the qualified product.
