Description

Technical Field

[0001] This utility model relates to the field of positioning structure technology, specifically to an auxiliary positioning structure for an automated visual defect detection device. Background Technology

[0002] With the rapid development of computer vision technology, automated visual inspection devices are now able to accurately inspect the appearance of products. Some electronic chips or precision metals need to undergo surface defect inspection before leaving the factory.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216747455U, which discloses a visual inspection device for motherboard defects. The device includes an image acquisition device, an image processing device, a rejection device, a controller, and an alarm. The device places the electronic chip to be tested on a conveyor belt and transports it to the image acquisition device for image acquisition. The image processor reads the image of the electronic chip to be tested from the image acquisition chip and compares the image of the electronic chip to be tested with a standard image model of the electronic chip to be tested.

[0004] The position of the imaging end of the above detection structure is fixed. Therefore, if the position of the chip is deviated when it is placed, it may lead to insufficient imaging and thus insufficient detection. Therefore, an auxiliary positioning structure for an automated visual defect detection device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary positioning structure for an automated visual defect detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning structure for an automated visual defect detection device, comprising a conveyor belt and a push plate, wherein the push plate is located at the top of the conveyor belt, a positioning component is installed at the top of the conveyor belt, the positioning component includes an extension column fixedly connected to the top of one side of the outer wall of the push plate, an electric telescopic rod fixedly installed at one end of the top outer wall of the conveyor belt, the output end of the electric telescopic rod being fixedly connected to the extension column, an extension plate fixedly connected to each of the two outer walls of the push plate, and a clamping plate rotatably connected to the bottom outer wall of each of the two extension plates.

[0007] As a further preferred embodiment of this technical solution, a connecting rod is rotatably connected to the top outer wall of each of the two extension plates. The two connecting rods are coaxially fixed to one end of the rotation shaft of each of the two clamping plates, and a gear is coaxially fixed to one end of the top of each of the two connecting rods.

[0008] As a further preferred embodiment of this technical solution, two fixing components are installed on the top of the conveyor belt, and the two fixing components are respectively located on both sides of the push plate.

[0009] As a further preferred embodiment of this technical solution, the fixing component includes a mounting rod fixedly connected to the top outer wall of the conveyor belt, a horizontally arranged rack slidably inserted at the top position of the mounting rod, the rack meshing with one of the gears, a baffle fixedly connected to one end of the rack, and the baffle and the mounting rod being fixedly connected to the same spring, the spring being sleeved on the outside of the rack.

[0010] It can move the object to be inspected directly below the external camera, ensuring that its end face can be fully captured, which is beneficial to improving the inspection effect and can adapt to the positioning of chips of different sizes. When the chip moves to the corresponding position of the push plate, the electric telescopic rod at the top of the conveyor belt is activated. The movable end of the electric telescopic rod can drive the push plate closer to the camera through the extension column. When the chip contacts the push plate, it will be gradually corrected to a flush state. The push plate drives the connecting rod to move synchronously through the extension plate. The gear at the top of the connecting rod is engaged during the movement and then flips and moves closer to the chip. With the cooperation of the two clamping plates, the chip will be gradually pushed to the middle position of the push plate, so that the chip is facing the external camera. If the chip is not facing the camera after being clamped by the clamping plate, the push plate will continue to move. Since the baffle is connected to the mounting rod through the spring, the rack can move as long as it overcomes the tension of the spring. Since the clamping plate cannot continue to flip due to the obstruction of the chip, the push plate can drive the rack to move outward along the mounting rod through the extension plate, connecting rod and gear, ensuring that the positioning work can be carried out smoothly.

[0011] As a further preferred embodiment of this technical solution, a rubber sleeve is fitted onto the ends of the two clamps that are far apart from each other.

[0012] As a further preferred embodiment of this technical solution, the push plate is arranged in a Z-shape.

[0013] This utility model provides an auxiliary positioning structure for an automated visual defect detection device, which has the following beneficial effects:

[0014] This invention, by setting up positioning and fixing components, can move the object to be detected directly below the external camera, ensuring that its end face can be completely captured, which improves the detection effect and can adapt to the positioning of chips of different sizes. When the chip moves to the corresponding position on the push plate, the electric telescopic rod at the top of the conveyor belt is activated. The movable end of the electric telescopic rod, through the extension column, drives the push plate closer to the camera. When the chip contacts the push plate, it will be gradually corrected to a flush state. The push plate drives the connecting rod to move synchronously through the extension plate. When the gear at the top of the connecting rod moves, Driven by gear meshing, the chip rotates and approaches towards it. With the cooperation of two clamping plates, the chip is gradually pushed to the middle position of the push plate, so that the chip can face the external camera. If the chip cannot face the camera after being clamped by the clamping plates, the push plate will continue to move. Since the baffle is connected to the mounting rod by a spring, the rack can move as long as it overcomes the tension of the spring. Since the clamping plates cannot continue to rotate due to the obstruction of the chip, the push plate can drive the rack to move outward along the mounting rod through the extension plate, connecting rod and gears, ensuring that the positioning work can be carried out smoothly.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 2 , Figure 3 and Figure 4As shown in this embodiment, an auxiliary positioning structure for an automated visual defect detection device includes a conveyor belt 1 and a pusher plate 301. The pusher plate 301 is located at the top of the conveyor belt 1. A positioning component 3 is installed on the top of the conveyor belt 1. The positioning component 3 includes an extension column 305 fixedly connected to the top of one side of the outer wall of the pusher plate 301. An electric telescopic rod 304 is fixedly installed at one end of the top outer wall of the conveyor belt 1. The output end of the electric telescopic rod 304 is fixedly connected to the extension column 305. An extension plate 302 is fixedly connected to both sides of the outer wall of the pusher plate 301. A clamping plate 303 is rotatably connected to the bottom outer wall of both extension plates 302.

[0022] Each of the two extension plates 302 has a connecting rod 306 rotatably connected to its top outer wall. The two connecting rods 306 are coaxially fixed to one end of the rotating shaft of each of the two clamping plates 303. A gear 307 is coaxially fixed to one end of the top of each of the two connecting rods 306.

[0023] Two fixing components 4 are installed on the top of the conveyor belt 1, and the two fixing components 4 are located on both sides of the push plate 301.

[0024] The fixed component 4 includes a mounting rod 403 fixedly connected to the top outer wall of the conveyor belt 1. A horizontally arranged rack 308 is slidably inserted into the top position of the mounting rod 403. The rack 308 meshes with one of the gears 307. A baffle 401 is fixedly connected to one end of the rack 308. The baffle 401 and the mounting rod 403 are fixedly connected to the same spring 402. The spring 402 is sleeved on the outside of the rack 308.

[0025] When the chip moves to the corresponding position on the pusher plate 301, the electric telescopic rod 304 at the top of the conveyor belt 1 is activated. The movable end of the electric telescopic rod 304, through the extension column 305, can drive the pusher plate 301 closer to the camera. When the chip contacts the pusher plate 301, it will be gradually corrected to a flush state. The pusher plate 301 drives the connecting rod 306 to move synchronously through the extension plate 302. The gear 307 at the top of the connecting rod 306 is engaged during the movement, and then flips and moves closer to the chip. With the cooperation of the two clamping plates 303, the chip will be gradually pushed to the middle position of the pusher plate 301. The chip is positioned so that it can face the external camera. If the chip is large, and it cannot face the camera after being clamped by the clamping plate 303, the push plate 301 will continue to move. Since the baffle 401 is connected to the mounting rod 403 through the spring 402, the rack 308 can move as long as it overcomes the tension of the spring 402. Since the clamping plate 303 cannot continue to rotate due to the obstruction of the chip, the push plate 301 can drive the rack 308 to move outward along the mounting rod 403 through the extension plate 302, the connecting rod 306 and the gear 307, ensuring that the positioning work can be carried out smoothly.

[0026] like Figure 1 and Figure 2As shown, a rubber sleeve 2 is fitted on the ends of the two clamping plates 303 that are far apart from each other. This helps to increase the friction between the clamping plates 303 and the chip, resulting in a better fixing effect and preventing the chip from shifting position.

[0027] like Figure 3 As shown, the pusher plate 301 is arranged in a Z-shape, which ensures that it can push the chip while not obstructing the imaging of the chip's edge.

[0028] This utility model provides an auxiliary positioning structure for an automated visual defect detection device, the specific working principle of which is as follows:

[0029] When the device is working, when the chip moves to the corresponding position on the pusher plate 301, the electric telescopic rod 304 at the top of the conveyor belt 1 is activated. The movable end of the electric telescopic rod 304, through the extension column 305, can drive the pusher plate 301 closer to the camera. When the chip contacts the pusher plate 301, it will be gradually corrected to a flush state. The pusher plate 301 drives the connecting rod 306 to move synchronously through the extension plate 302. The gear 307 at the top of the connecting rod 306 is engaged during the movement, and then flips and moves closer to the chip. With the cooperation of the two clamping plates 303, the chip will be gradually pushed onto the pusher plate. At the middle position of 301, the chip can face the external camera. If the chip is clamped by the clamping plate 303 but still cannot face the camera, the push plate 301 will continue to move. Since the baffle 401 is connected to the mounting rod 403 through the spring 402, the rack 308 can move as long as it overcomes the tension of the spring 402. Since the clamping plate 303 cannot continue to rotate due to the obstruction of the chip, the push plate 301 can drive the rack 308 to move outward along the mounting rod 403 through the extension plate 302, the connecting rod 306 and the gear 307, ensuring that the positioning work can be carried out smoothly.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
