Description

Technical Field

[0001] This utility model belongs to the field of AOI testing technology, and in particular relates to an automatic cyclic feeding and storage AOI testing device. Background Technology

[0002] AOI inspection equipment, short for Automated Optical Inspection Equipment, is an automated device that uses optical principles and image processing technology to automatically inspect, identify, and judge products or workpieces. Simply put, it is like a highly specialized "machine eye" that can automatically check whether a product has defects or errors. The electronics manufacturing industry is the most widespread application of AOI, mainly used to detect defects in electronic components such as PCBs (Printed Circuit Boards), such as mis-assembly, missing components, incorrect polarity, solder joint defects, open circuits / short circuits, etc.

[0003] In practical use, in order to more comprehensively discover different types of defects in products (such as misalignment, incorrect components, insufficient solder, excessive solder, etc.), AOI inspection equipment is usually equipped with multiple light sources to perform multiple imaging and inspection analyses on the same area or component using different combinations of light sources, so as to obtain richer information and improve the accuracy of inspection.

[0004] However, multiple inspections by AOI inspection equipment means that the camera or worktable needs to be moved multiple times, which takes more time to complete the inspection of the entire product, thereby reducing the operating speed of the production line. Moreover, after each movement, the camera or worktable needs to be accurately positioned to the next area. If there is a slight error in positioning, it will lead to errors in the inspection results. Therefore, an automatic cyclic feeding and storage AOI inspection equipment is needed to solve the above problems. Utility Model Content

The storage bin is installed at the end of the feeding conveyor belt away from the hexagonal turntable. A pair of detection surfaces are respectively aligned with two adjacent placement slots. The feeding conveyor belt is tractably mounted on the worktable.

[0010] A feeding mechanism is installed on the worktable.

[0011] In a further technical solution, the hexagonal turntable has a movable groove on the inner wall of the placement groove, and the feeding mechanism further includes an abutment plate and a return spring. Multiple abutment plates and return springs are provided. One end face of each abutment plate is slidably placed in each movable groove. The return spring is placed in the movable groove, and both ends of the return spring are respectively connected to the abutment plate and the inner wall of the movable groove. The abutment plate is placed between a pair of clamping plates.

The feeding pusher plate is disposed at one end of the feeding telescopic column. The output shaft of the cylinder is connected to the feeding telescopic column. The feeding pusher plate is aligned with the abutment plate disposed in the moving groove at the bottom of the hexagonal turntable.

[0013] A further technical solution is that the feeding pusher includes a push rod, a rotating rod, a mounting frame, a feeding motor, and rotating columns. The rotating rod is rotatably mounted on the mounting frame and inserted into the middle position of the push rod. The feeding motor is mounted on the mounting frame, and the output shaft of the feeding motor is connected to the rotating rod.

[0017] This invention features a feeding mechanism comprising a feeding conveyor belt, a hexagonal turntable, a clamping plate, a telescopic column, a return spring, and a feeding pusher. The hexagonal turntable has placement slots, and the clamping plate is positioned within these slots. One end of the feeding conveyor belt aligns with the uppermost placement slot of the hexagonal turntable, and a pair of detection surfaces align with adjacent placement slots. Products in the storage bin move sequentially toward the hexagonal turntable. Once a product reaches a position close to the feeding pusher, it is sequentially transferred from the feeding conveyor belt to each placement slot of the hexagonal turntable.

The feeding pusher plate is positioned at one end of the feeding telescopic column, aligned with the abutment plate. After different inspection surfaces of the product are sequentially inspected, the hexagonal turntable rotates the inspected product to directly above the feeding conveyor belt. Subsequently, the activated cylinder drives the feeding telescopic column to extend, thereby moving the feeding pusher plate closer to the abutment plate. The feeding pusher plate pushes the abutment plate and the product abutting against the abutment plate along a moving groove, so that the inspected product is pushed from between a pair of clamps onto the feeding conveyor belt. This eliminates the need for manual operation by workers, demonstrating the high degree of automation of the equipment.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 4 As shown, this utility model embodiment provides an automatic circulating feeding and storage AOI inspection device, including:

[0028] The main body of the equipment 1 includes a workbench 11, a storage bin 12, and a testing component 13. The storage bin 12 and the testing component 13 are both installed on the workbench 11. The testing component 13 has a pair of different testing surfaces 131.

[0029] The feeding mechanism 2 includes a feeding conveyor belt 21, a hexagonal turntable 22, clamping plates 23, telescopic columns 24, return springs 25, and a feeding pusher 26. The cross-section of the hexagonal turntable 22 is a regular hexagon, and each side of the hexagonal turntable 22 is provided with a placement slot 221. Multiple pairs of clamping plates 23 are provided, and each pair of clamping plates 23 is positioned opposite each placement slot 221. Multiple sets of telescopic columns 24 and return springs 25 are provided, with at least two telescopic columns 24 and at least two return springs 25 in each set. The ends of the telescopic columns 24 and return springs 25 are... All components are connected to the inner wall of the clamping plate 23 and the placement groove 221. The return spring 25 is sleeved on the telescopic column 24. The hexagonal turntable 22 is rotatably mounted on the worktable 11. The feeding pusher 26 is rotatably mounted at a predetermined distance above the feeding conveyor belt 21. One end of the feeding conveyor belt 21 is aligned with the uppermost placement groove 221 of the hexagonal turntable 22. The storage bin 12 is installed at the end of the feeding conveyor belt 21 away from the hexagonal turntable 22. A pair of detection surfaces 131 are respectively aligned with two adjacent placement grooves 221. The feeding conveyor belt 21 is tractably mounted on the worktable 11.

[0030] The feeding mechanism 3 is installed on the workbench 11;

[0031] In this embodiment, firstly, workers use robotic arms or suction cups to sequentially transfer the products in the storage bin 12 to one end of the feeding conveyor belt 21 away from the hexagonal turntable 22. The products move towards the hexagonal turntable 22 under the conveyor belt 21. When the products move to a position close to the feeding pusher 26, they are sequentially transferred from the feeding conveyor belt 21 to each placement slot 221 of the hexagonal turntable 22 by the feeding pusher 26. At this time, the telescopic column 24 and the return spring 25 are compressed. The hexagonal turntable 22 rotates intermittently, thereby causing the products in the placement slots 221 to rotate until they are aligned with a pair of detection surfaces 131 on the detection piece 13. In this way, the pair of detection surfaces 131 sequentially perform secondary imaging and detection analysis on each product, which not only reflects the degree of automation of the equipment, but also eliminates the need to move or reposition the detection piece 13, improves the operating speed of the production line, and ensures the accuracy of the detection results.

[0032] Specifically, the hexagonal turntable 22 has a movable groove 222 on the inner wall of the placement groove 221. The feeding mechanism 2 also includes an abutment plate 27 and a return spring 28. Multiple abutment plates 27 and return springs 28 are provided. One end face of each abutment plate 27 is slidably placed in each movable groove 222. The return spring 28 is placed in the movable groove 222, and both ends of the return spring 28 are respectively connected to the abutment plate 27 and the inner wall of the movable groove 222. The abutment plate 27 is placed between a pair of clamping plates 23.

[0033] In this embodiment, the end of the push rod 261 on which the rotating column 265 is mounted pushes the product between a pair of clamping plates 23 until one end face of the product abuts against the abutting plate 27 between the pair of clamping plates 23.

[0034] Specifically, the unloading mechanism 3 includes an unloading conveyor belt 31, an unloading push plate 32, a cylinder 33, and an unloading telescopic column 34. The unloading conveyor belt 31 is tractably disposed at a predetermined distance below the loading conveyor belt 21, and one end of the unloading conveyor belt 31 is disposed at a predetermined distance below the placement groove 221 at the bottom of the hexagonal turntable 22. The unloading push plate 32 is disposed at one end of the unloading telescopic column 34. The output shaft of the cylinder 33 is connected to the unloading telescopic column 34. The unloading push plate 32 is aligned with the abutment plate 27 disposed in the moving groove 222 at the bottom of the hexagonal turntable 22.

[0035] In this embodiment, after the different inspection surfaces 131 of the product being inspected 13 are inspected in sequence, the hexagonal turntable 22 continues to rotate, thereby driving the inspected product to rotate directly above the unloading conveyor belt 31; then, the activated cylinder 33 drives the unloading telescopic column 34 to extend, thereby driving the unloading push plate 32 at the other end of the unloading telescopic column 34 to move towards the abutment plate 27; the unloading push plate 32 pushes the abutment plate 27 and the product abutting against the abutment plate 27 to move along the moving groove 222, so that the inspected product is pushed from between a pair of clamping plates 23 onto the unloading conveyor belt 31, without the need for manual operation by workers, demonstrating the degree of automation of the equipment;

[0036] Specifically, the feeding pusher 26 includes a push rod 261, a rotating rod 262, a mounting frame 263, a feeding motor 264, and a rotating column 265. The rotating rod 262 is rotatably mounted on the mounting frame 263 and inserted into the middle position of the push rod 261. The feeding motor 264 is mounted on the mounting frame 263, and the output shaft of the feeding motor 264 is connected to the rotating rod 262. A pair of rotating columns 265 are provided, and the pair of rotating columns 265 are rotatably disposed at both ends of the push rod 261.

[0037] In this embodiment, once the product moves to a position close to the feeding pusher 26, the feeding motor 264, after being started, drives the rotating rod 262 to rotate, thereby causing the push rod 261 and the rotating columns 265 at both ends of the push rod 261 to rotate axially around the rotating rod 262; the end of the push rod 261 on which the rotating columns 265 are mounted pushes the product between a pair of clamping plates 23;

[0038] Specifically, the main body 1 of the equipment also includes a pole 14, which is fixedly installed on the workbench 11, a hexagonal turntable 22 is rotatably set on the pole 14, and a cylinder 33 is installed on the pole 14;

[0039] Specifically, the two ends of the clamp 23 are set to be inclined, and both inclined ends of the clamp 23 are set to be open.

[0040] The working principle of this utility model is as follows:

[0041] In the initial state, the product to be tested is placed in the storage bin 12, and the push rod 261 is rotated to a position parallel to the conveying direction of the feeding conveyor belt 21;

[0042] First, workers use robotic arms or suction cups to sequentially transfer products from storage bin 12 to the end of the feeding conveyor belt 21 away from the hexagonal turntable 22. The products move towards the hexagonal turntable 22 under the conveyor belt 21. When the products move to a position close to the feeding pusher 26, the feeding motor 264, after starting, drives the rotating rod 262 to rotate, which in turn drives the push rod 261 and the rotating columns 265 at both ends of the push rod 261 to rotate axially around the rotating rod 262. The end of the push rod 261 with the rotating columns 265 pushes the products between a pair of clamping plates 23 until one end of the product abuts against the abutment plate 27 between the pair of clamping plates 23. In this way, the products are sequentially transferred from the feeding conveyor belt 21 to each placement slot 221 of the hexagonal turntable 22. At this time, the telescopic column 24 and the return spring 25 are compressed.

[0043] At the same time, the hexagonal turntable 22 rotates intermittently, thereby driving the product in the placement slot 221 to rotate and align with a pair of detection surfaces 131 on the detection piece 13; in this way, the pair of detection surfaces 131 sequentially perform secondary imaging and detection analysis on each product, which not only reflects the degree of automation of the equipment, but also eliminates the need to move or reposition the detection piece 13, improves the operating speed of the production line, and ensures the accuracy of the detection results.

[0044] After the different inspection surfaces 131 of the product being inspected are inspected in sequence, the hexagonal turntable 22 continues to rotate, thereby driving the inspected product to rotate directly above the unloading conveyor belt 31. Subsequently, the activated cylinder 33 drives the unloading telescopic column 34 to extend, thereby driving the unloading push plate 32 at the other end of the unloading telescopic column 34 to move towards the abutment plate 27. The unloading push plate 32 pushes the abutment plate 27 and the product abutting against the abutment plate 27 to move along the moving groove 222, so that the inspected product is pushed from between a pair of clamping plates 23 onto the unloading conveyor belt 31 without manual operation by workers, demonstrating the degree of automation of the equipment.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
