[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example

[0039] The present invention will now be further described with reference to the accompanying drawings.

[0040] like Figures 1 to 5 As shown, this embodiment provides a fully automatic assembly machine, including a frame 10, and also including an assembly table 11, a vibratory feeder 12, a screw assembly assembly 13 and a machine vision assembly 14 located on the frame 10. The assembly table 11 is located below the screw assembly assembly 13. A conveyor belt assembly 15 for conveying products is also installed on the assembly table 11. Centered stop block assemblies 33 are symmetrically distributed on the assembly table 11 with the conveyor belt assembly 15 as the center.

[0041] The working principle and beneficial effects of the above technical solution are as follows:

[0042] This utility model discloses a fully automatic assembly machine. Screws are placed into a vibratory feeder 12, and the product is placed on a conveyor belt assembly 15. The conveyor belt assembly 15 moves the product closer to the centering block assembly 33. Due to the symmetrical distribution of the two sets of centering block assemblies 33, the conveyor belt assembly 15 causes the product to abut against the two sets of centering block assemblies 33. While the centering block assemblies 33 prevent the product from continuing to move, they also center the product, allowing the machine vision assembly 14 to accurately collect position information. Then, the machine vision assembly 14 works, collecting image information of the product's upper surface and precisely locating the screw hole. Finally, the screw assembly assembly 13 works, screwing the screw into the screw hole. This utility model provides a fully automatic assembly machine that can complete product correction and alignment without manual intervention, improving product placement efficiency.

[0043] In one embodiment, the screw assembly 13 includes a transverse unit 16, a linear module, a rear rotating cylinder 17, and a front suction cup 18. The transverse unit 16 is located on the assembly table 11, the linear module is mounted on the actuating end of the transverse unit 16, the rear rotating cylinder 17 is mounted on the actuating end of the linear module, and the front suction cup 18 is mounted on the actuating end of the rear rotating cylinder 17.

[0044] The working principle of the above technical solution is as follows:

[0045] When the lateral movement unit 16 operates, the front suction cup 18 moves closer to the vibratory feeder 12. The linear module drives the front suction cup 18 to fall, picking up the assembled screws delivered one by one by the vibratory feeder 12. Then, the lateral movement unit 16 reverses its operation, and the front suction cup 18 moves closer to the assembly table 11. The linear module operates, causing the front suction cup 18 to precisely land at each screw hole position captured by the machine vision component 14. Next, the rear rotary cylinder 17 operates, thereby screwing the assembled screws into the screw holes. The rear rotary cylinder 17 and the front suction cup 18 stop operating simultaneously. Machine vision is a mature technology and will not be elaborated further here.

[0046] In one embodiment, the lateral movement unit 16 includes:

[0047] Lower fixing seat 21, two sets of lower fixing seats 21 are symmetrically distributed on the assembly table 11 with the conveyor belt assembly 15 as the center;

[0048] A transverse sliding screw 22 is mounted on a lower fixed base 21. A transverse sliding seat 1 is sleeved on the transverse sliding screw 22 and is slidably connected to the lower fixed base 21.

[0049] The fixed crossbeam 23 is located above the assembly platform 11. Both ends of the fixed crossbeam 23 are connected to the horizontal sliding seat 1 through the vertical mounting bracket 24. The linear module is installed on the fixed crossbeam 23.

[0050] A transverse motor 25 is mounted on a lower fixed base 21, and one end of a transverse screw 22 is mounted on the actuating end of the transverse motor 25.

[0051] The working principle and beneficial effects of the above technical solution are as follows:

[0052] When the transverse motor 25 operates, it drives the transverse screw 22 installed at its actuating end to rotate on the lower fixed seat 21, thereby driving the transverse seat 1 sleeved on the transverse screw 22 and the fixed crossbeam 23 connected to the transverse seat 1 through the vertical mounting bracket 24 to move laterally. In this way, the linear module installed on the fixed crossbeam 23 can switch positions between the vibratory plate 12 and the assembly table 11.

[0053] In one embodiment, the linear module consists of a longitudinal linear module 19 and a lifting linear module 20. The longitudinal linear module 19 is mounted on a fixed crossbeam 23, and the lifting linear module 20 is mounted on the actuating end of the longitudinal linear module 19.

[0054] The working principle of the above technical solution is as follows:

[0055] With the cooperation of the longitudinal linear module 19 and the lifting linear module 20, the lifting and longitudinal position changes of the front suction cup 18 are realized.

[0056] In one embodiment, the machine vision component 14 includes:

[0057] Side mounting base 26, which is mounted on the side end of the frame 10;

[0058] A transverse screw 27 is mounted on a side mounting base 26. A transverse seat 2 is sleeved on the transverse screw 27 and is slidably connected to the side end of the frame 10.

[0059] A second transverse motor 28 is mounted on a side mounting base 26, and one end of a second transverse screw 27 is mounted on the actuating end of the second transverse motor 28.

[0060] Side mounting bracket 29 is set with a right-angle bend. The vertical section of the side mounting bracket 29 is mounted on the transverse sliding seat 2, and the horizontal section of the side mounting bracket 29 extends towards the assembly table 11.

[0061] Industrial camera 30 is mounted on the horizontal section of side mounting bracket 29.

[0062] The working principle and beneficial effects of the above technical solution are as follows:

[0063] The transverse motor 28 operates, thereby driving the transverse screw 27 mounted on its actuating end to rotate on the side mounting base 26, which in turn drives the transverse seat 2, which is sleeved on the transverse screw 27, and the industrial camera 30 connected to the transverse seat 2 via the side mounting bracket 29 to move laterally. The industrial camera 30 collects image information of the upper surface of the product located on the assembly table 11 to accurately locate the screw hole position.

[0064] In one embodiment, the discharge end of the vibratory feeder 12 is provided with a linear feeding track 32 for conveying screws one by one.

[0065] The beneficial effects of the above technical solution are as follows:

[0066] The linear feeding track 32 facilitates the feeding of screws one by one.

[0067] In one embodiment, the conveyor belt assembly 15 includes a conveyor roller group and a conveyor belt sleeved on the conveyor roller group, and the conveyor belt is provided with correction ribs 34 at equal intervals, the correction ribs 34 being distributed along the width direction of the conveyor belt.

[0068] The working principle and beneficial effects of the above technical solution are as follows:

[0069] The conveyor roller assembly rotates, thereby driving the conveyor belt fitted on it to rotate cyclically. After the product is placed on the conveyor belt, the product is positioned between adjacent correcting ribs 34. As the conveyor belt moves the product, it abuts against one of the centering block assemblies 33. The centering block assembly 33 slows down the product's movement speed while simultaneously centering the product. Because the centering block assembly 33 blocks the product, it cannot move forward, and the bottom of the product rests against the correcting rib 34. Thus, when the centering block assembly 33 centeres the product, it can only slide along the correcting rib 34, thereby preventing the product from tilting.

[0070] In one embodiment, the centering block assembly 33 includes:

[0071] Lower fixing plate 42 is detachably installed on frame 10 by fixing screws;

[0072] The wedge-shaped stop 35 is slidably installed on the top of the lower fixed plate 42. The wedge-shaped stop 35 is a hollow structure, and the inclined end of the wedge-shaped stop 35 is set close to the conveyor belt assembly 15.

[0073] Adjusting screw 36 is rotatably mounted on vertical mounting plate 37, which is fixedly mounted on lower mounting plate 42;

[0074] Side limiting plate 38 is vertically installed on the lower fixed plate 42 and passes through the wedge-shaped stop 35;

[0075] Screw block 39 is fixedly installed on wedge-shaped stop block 35 and is sleeved on adjusting screw 36.

[0076] The working principle and beneficial effects of the above technical solution are as follows:

[0077] According to the different sizes and specifications of the products, after manually adjusting the adjusting screw 36, the screw block 39 installed on the adjusting screw 36 and the lower wedge-shaped stop block 35 connected to the screw block 39 slide along the side limiting plate 38 on the lower fixed plate 42. After the position is properly adjusted, the conveyor belt drives the product to move. One side of the product abuts against the inclined end of one of the wedge-shaped stops 35. The wedge-shaped stops 35 slow down the product's walking speed and correct the product's centering. The bottom end of the product abuts against the correction rib 34. In this way, when the centering stop block assembly 33 corrects the product's centering, the product can only slide along the correction rib 34, thereby preventing the product from tilting. After the product abuts against the inclined ends of the two sets of wedge-shaped stops 35, the conveyor roller assembly stops rotating. The product stops at the preset position in the center so that the machine vision component 14 can collect image information of the product's upper surface.

[0078] Preferably, the adjusting screw 36 is mounted on the vertical mounting plate 37 via a bearing, and an adjusting block 40 is installed on the end of the adjusting screw 36 near the vertical mounting plate 37. The lower fixed plate 42 is marked with a scale line 41 for measuring the moving distance of the wedge-shaped stop 35.

[0079] The working principle and beneficial effects of the above technical solution are as follows:

[0080] The setting of the adjustment block 40 makes it easy to rotate the adjustment screw 36 using tools, while the setting of the scale line 41 makes it easy to see the adjustment distance intuitively.

[0081] In one embodiment, a support leg 31 is mounted on the bottom end of the frame 10.

[0082] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
